How Can You Determine What Is Wrong with an Air Conditioner That Is Not Cooling?

I assume you have central air in your house so I'll answer under that assumption. The cause could be many things. A refrigerant leak would cause no cooling. Most a/c units have refrigerant that uses high (or medium) pressure so any leak could cause you to lose most of or all of the refrigerant charge. A lack of proper airflow across the evaporator coil (the coil inside of your indoor unit) could cause a lack of cooling. This could simply be a really dirty air filter. Other things to check for would be a broken belt on the supply fan, a bad condenser fan motor, a bad compressor, a blown fuse. It could really be a number of things. You can narrow it down by eliminating some items. For example if your ac unit is blowing air out of the diffusers but it's just not cold air, it likely means the air filter is ok and the indoor fan is still working properly. Is the outside compressor running? Is the outside condenser fan running?Is the thermostat set to cooling (seems silly but I've seen that be the cause)?Do you see condensation draining out of your condensate drain line? A plugged drain pan could cause the condensate pan to fill up with water and there's a safety switch to shut the unit off to prevent it from overflowing the pan and leaking water into your house. If your not comfortable visually checking some of these things on your own your best bet is to call an HVAC repairman to come inspect the unit. He or she will likely put their set of refrigerant / pressure gauges on it and can tell fairly quickly what the problem is for you. Hope this helps!How can you determine what is wrong with an air conditioner that is not cooling?.

1. what kind of cooling systems are there?

Its not hard at all to add a fan. Check out the link below to look for fans. If you look at the back of your computer there should be a bunch of holes, you can buy a 120mm fan and put it there to cool it down a lot

2. what is the best heating and cooling unit?

The BEST and most expensive would be the Carrier Infinity system. While there are several other "brands" to choose from like anything you pay for the name. Other considerations would be (no particular order) Trane, Bryant, American standard, payne, goodman, ICP just to rattle off a few. Just brace yourself for the price when they give it to you.

3. cooling wines quickly....?

If you are in a bind Use an ice bucket (water is must) and salt! It superchills the wine. Otherwise 5 degrees every1/2 hour.

4. Central Air Not Cooling Well?

Also, the air coming out of the vents is from your air handler INSIDE the house. Outside is just the compressor, etc. If you've got too little air coming out of your vents and you had more before it must be something going on your air handler. Probably not something you can fix easily yourself.

5. Cooling down room with just a water

Firstly it has to be understood that, given enough time, both water and air will end up at the same temperature, call it $T_e$.Now assuming there are no heat losses to the rest of the universe, with the air initially at $T_air$ and the water initially at $T_water$ then the air 'loses' heat energy according to:$$Delta Q=m_airc_air(T_air-T_e)$$and the water 'gains' heat energy according to: $$Delta Q=m_waterc_water(T_e-T_water)$$where the $c$ are specific heat capacities.So we have:$$boxedm_airc_air(T_air-T_e)=m_waterc_water(T_e-T_water)$$from which the unknown $T_e$ can be extricated easily. If $T_e$ is known then another unknown can be calculated.

What Is the Difference Between Small Program and Official Account and APP?
The official account and the applet are all based on WeChat platform, and WeChat's own more than ten billion traffic is also directed to the small program and the official account. What is the difference between a small program and a official account? What's the difference between and app?What is Wx applet?It is an application that can be used without downloading and installing. It realizes the dream of "within reach" of the application. Users can open the application by scanning or searching.What is the WX official account?WX official account is an application account applied by developers or businesses on the WX public platform. The account is interconnected with QQ accounts. Through official account, merchants can realize the all-round communication and interaction with specific groups of texts, pictures, voice and videos on the WX platform. A mainstream online and offline Wx interactive marketing mode has been formed.What is app?App mainly refers to the software installed on smart phones, which improves the shortcomings and personalization of the original system. It is the main means to improve the functions of mobile phones and provide users with richer use experience. The operation of mobile phone software requires corresponding mobile phone systems. As of June 1, 2017, the main mobile phone systems are Apple's IOS, Google's Android (Android) system, Symbian platform and Microsoft platform.The difference between the small and the official account is:The official account is mainly used for information transmission to realize the connection between people and information. With H5, simple interaction can be maintained. The key is marketing promotion and information transmission, which are mainly supplemented by simple service items. The official account is developed and designed and operated according to the traditional H5. The traditional H5 running environment is browser. You can understand that the official account is a website.The actual operation of small program sequence is very simple. You can enter it by directly scanning the QR code or clicking open. The Wx applet is developed and designed according to the language of the mobile phone Wx itself. The front-end framework and styles are stored in the Wx cloud, but the data is enabled for back-end development. Therefore, it can be opened quickly and provide a smooth experience like an app.Differences between small process sequence and app:App for all smartphone users, about 2.3 billion; The small program is oriented to Wx users, about 800 million users. In terms of function realization, app can realize complete functions and strong flexibility; The applet is limited to the interface functions provided by Wx. Small range sequence low frequency, non rigid demand, lightweight, single function, high frequency rigid demand still depends on app.The advantage of small procedure sequence is that it is backed by Wx and the drainage method is easy to use. However, Wx has many restrictions on the small process sequence, especially at the level of traffic acquisition. Many applied marketing strategies are strictly prohibited by Tengxun in Wx small process sequence, such as three-level distribution. Tengxun is seriously banned and has no prior warning, so there is no way to appeal; The internal functions and contents of the app are fully controlled by the operator.

Air-cooled engines do not require coolant service, and do not suffer damage from freezing, two commonly cited advantages for air-cooled engines. However, coolant based on propylene glycol is liquid to −55 °C, colder than is encountered by many engines; shrinks slightly when it crystallizes, thus avoiding damage; and has a service life over 10,000 hours, essentially the lifetime of many engines.— — — — — —Planetary coolingA body of icy or rocky material in outer space may, if it can build and retain sufficient heat, develop a differentiated interior and alter its surface through volcanic or tectonic activity. The length of time through which a planetary body can maintain surface-altering activity depends on how well it retains heat, and this is governed by its surface area-to-volume ratio. For Vesta (r=263 km), the ratio is so high that astronomers were surprised to find that it did differentiate and have brief volcanic activity. The moon, Mercury and Mars have radii in the low thousands of kilometers; all three retained heat well enough to be thoroughly differentiated although after a billion years or so they became too cool to show anything more than very localized and infrequent volcanic activity. As of April 2019, however, NASA has announced the detection of a "marsquake" measured on April 6, 2019 by NASA's InSight lander. Venus and Earth (r>6,000 km) have sufficiently low surface area-to-volume ratios (roughly half that of Mars and much lower than all other known rocky bodies) so that their heat loss is minimal. .— — — — — —Passive coolingPassive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural cooling). Natural cooling utilizes on-site energy, available from the natural environment, combined with the architectural design of building components (e. g. building envelope), rather than mechanical systems to dissipate heat. Therefore, natural cooling depends not only on the architectural design of the building but on how the site's natural resources are used as heat sinks (i.e. everything that absorbs or dissipates heat). Examples of on-site heat sinks are the upper atmosphere (night sky), the outdoor air (wind), and the earth/soil— — — — — —CoolingCooling of the astronaut with an SAS is generally achieved with evaporation from body perspiration which is emitted from the suit in all directions.

Antifreeze itself is usually ethylene glycol or propylene glycol (with a small amount of corrosion inhibitor). • a series of galleries cast into the engine block and cylinder head, surrounding the combustion chambers with circulating liquid to carry away heat; • a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine; • a water pump, usually of the centrifugal type, to circulate the coolant through the system; • a thermostat to control temperature by varying the amount of coolant going to the radiator; • a fan to draw cool air through the radiator.

The Key Factors Restricting the Development of High-power Charging in China Are That the Power Batte
The Key Factors Restricting the Development of High-power Charging in China Are That the Power Batte
If you can run 200 kilometers after charging for 5 minutes, the endurance anxiety of electric vehicle owners will be completely solved. In this cold winter, people who bought "electric dad" may be more eager to look forward to this day than anyone else. Fortunately, people in the industry have been working hard.European and North American automobile manufacturers have been cooperating to develop and launch a faster automobile charging network, such as the 350 kW fast charging demonstrated by ABB in Switzerland in April this year, which claims an 8-minute battery life of 200 kilometers. However, Porsche has been better. Now, in cooperation with BMW, it has set up a set of fast charging piles with a prototype power of 450KW in its German automotive research institute, which is more than three times the power of Tesla super charging pile. It is officially declared that it can charge 100 kilometers in 3 minutes and 80% in 15 minutes.China has also been calling for high-power fast charging. At present, some enterprises have carried out research and development of high-power fast charging technology, such as star charging and Wanma new energy, and developed fast charging products of 360kw and higher power. But at the same time, there is also a phenomenon that Chinese car enterprises are not as active and aggressive as those in Europe and the United States. What is the reason behind it?High power fast charging is an inevitable trend. Europe and the United States have raised the flag of 350 kW or even 450 kW. Can China keep up with them? What is the stage of high-power charging in China? What are the constraints of its development?The cost has doubled, the power battery can't keep up, and the cooling system is at riskWhether it is necessary for China to keep up with the high-power charging of more than 350 kW depends on the development process of electric vehicles and the demand of the market. Yu Hongxi, manager of Beijing Bodian electric vehicle test department, told first electric that at present, the cost increase brought by the voltage platform rise of the whole vehicle and the voltage level rise of the power battery and the improvement of safety performance requirements are the key factors restricting the development and application of high-power charging.First of all, for car users, of course, the shorter the charging time, the better, but at the same time, it means that the cost will increase exponentially. The charging power is actually the value obtained by multiplying the voltage and current. If the current is increased, the charging cable will become very thick. Therefore, generally speaking, the means to increase the power is to increase the voltage. Increasing the voltage will increase the voltage level of the parts and electrical parts of the whole vehicle, and the cost of the vehicle will double. In addition, all the corresponding requirements around the R & D, design, assembly and maintenance of power batteries should also be greatly improved in order to meet the needs of high-power charging. The voltage level of the existing power battery is about 400 V. if it is increased to 1000 V, the cost will actually increase several times.The high cost will eventually be reflected in the price. You know, the price of Porsche 350kW charging car is very high, more than 10 million yuan. Yu Hongxi said frankly, "this is a real cost, not to say, this is a very realistic thing. You may technically be able to achieve a charging voltage of 1200 V or even 1500 V when you make a car, but who will buy your car if it sells for seven or eight million or even more than ten million?"Secondly, if the voltage of the power battery is increased, the current output will increase accordingly, and the heating capacity of the charging cable will also increase. If the heating capacity is large, cooling measures should be taken. At present, the liquid cooling system is mainly used, that is, a cooling liquid circuit is laid on the charging cable, which is similar to the compressor of air conditioner. The compressor is installed in the charging cabinet, and then the liquid circuit is installed in the charging power supply. However, this brings a very prominent problem: once the cooling system fails, it will put users in an extremely dangerous situation. Yu Hongxi revealed that around April this year, a Porsche caught fire when charging in a 4S store in Europe because the cooling system failed.Another point to consider is the interface and charging protocol between the charging system and the vehicle. When the charging power reaches more than 350 kW, the specification of its interface and charging protocol is another system, which takes time in terms of technical implementation.Therefore, on the whole, the doubling of the cost and the security of the cooling system are the key factors restricting the development of high-power charging.Five year commercial possibility is basically zero?Although there are many constraints, the industry generally believes that high-power charging must be a trend in the future. Liu Yongdong, deputy director of the standardization center of China electricity Union, said that the high-power charging technology is a supplement to the existing charging technology route of version 2015. For a long time in the future, the high-power charging technology is the application demand under certain scenarios, will coexist with the existing charging technology route for a long time, and will not replace the existing charging technology.So, if the technical difficulties are overcome, what is the possibility of commercial use?Yu Hongxi pointed out that when the technology level of mass products such as automobiles is improved, the cost is reduced to a reasonable level, and the safety is guaranteed, this is the time point when they can really be put on the market for commercial use. He judged, "I personally think that raising the charging voltage or the charging voltage of power battery to such a high level is a medium and long-term development process, and the possibility of commercial use within five years is basically zero."In this regard, Zhu Jianzhong, general manager of Xingxing charging Beijing company, said that the high-power equipment has actually met the requirements. The high-power charging equipment of Xingxing charging and Porsche supporting liquid cooling system has been offline, so the key is to see whether the power battery at the car end can reach the corresponding level. "In fact, the battery in Ningde era already has a 4C charging rate. It is used in a number of taxis for high-power charging, but we heard that the current is still limited due to domestic safety considerations. Therefore, it can be done from a technical point of view. As for whether it is commercial for five years or three years, in fact, we mainly reserve technology and knowledge first, which is equivalent to being in a dilemma In a wait-and-see state, we are also waiting for the two watersheds of 2020 and 2025. "Liu Yongdong believes that high-power charging technology, as a systematic project, takes 2-3 years from the technology proposal to the completion of standard formulation. In order to apply the development plan of automobiles around 2020, it is necessary to pay close attention to the research, engineering practice and standard pre research of high-power charging technology.Xingxing charging 500kW liquid cooling high power charging equipmentStandard setting car companies are not active, and State Grid and charging facility operators cannot entertain themselvesFor the development stage of high-power charging, there have been undisclosed commercial applications abroad, such as high-power charging will be used in the maintenance and sample vehicle display in 4S stores, but it is still in the preliminary exploration stage in China. Although some charging facility operators have been able to achieve equipment of 350 kW and above, China has not issued specific standards, and the vehicle terminal has not been equipped with vehicle related systems. Why is that? Because there is a fundamental difference between China and foreign countries in the research and development of high-power technology and the formulation of standards.In Europe and the United States, charging facilities are dominated by car enterprises in R & D, construction and operation. Most of the major shareholders behind some commercial charging facility operators are also car enterprises. For example, lonity charging network is jointly established by four automobile giants such as BMW, Mercedes, Ford and Volkswagen, and Tesla in the United States is also establishing charging facilities. Therefore, high-power charging is actually promoted by car enterprises, and the car and electric system are doing it together.In China, at present, car companies do not have particularly high enthusiasm for the R & D and standard formulation of charging facilities, mainly because the State Grid and equipment manufacturers dominate, and the standard system of charging facilities is currently led by China Power Council. An industry insider told first electric that it seems that they are "entertaining themselves". No matter what your car needs, do it yourself. "For example, many charging facility operators in China are pushing 60kW and 120kw, but most cars in the market do not need such high charging power; In contrast, this situation does not exist in Europe and the United States, because car companies dominate.On August 28, 2018, China Power Council signed a technical and standards cooperation agreement with Japan electric vehicle fast charger Association (chademo), which plans to jointly promote high-power charging technology, interaction technology between electric vehicles and power grid and international standards. Yu Hongxi revealed that at present, the charging interface mentioned earlier in China has basically existed, that is, the national standard from Japan, which is a plug-in and split interface design, and other work is still in progress. The original plan was to release the interface standard at the end of this year or early next year, but now it must be postponed. Because it is necessary to upgrade and match the whole vehicle system to raise the vehicle to the charging level of 350 kW, and there is no plan to make such a sample vehicle for a joint venture or independent brand in China, so the actual operation cannot be carried out in the test stage, and the test can only be carried out in a simulated experimental environment. Without actual combat, of course, there is no official declaration.High power charging is not just a charging system, but should mainly serve the car. Only when there is demand for cars can the charging system have market space. If there is no demand for cars, R & D may be easy, but it will lose its original meaning. There is no effective communication and cooperation between car enterprises and charging equipment manufacturers, which has always been a problem in the industry. In this case, it is not easy to realize the idea of trying to keep up with foreign countries in promoting high-power charging. Yu Hongxi also called on car companies in the industry and companies in the charging facilities related industrial chain to work together to do a good job in the industry, so as to better comply with the development trend of high-power charging in the future.

Motorcycles are no exception to this rule and the cooling system on them is very important. Knowing how the cooling system works can prevent a rider from overheating their engine which can prevent costly fixes. If you are going to own a motorcycle, make this one of your priorities to understand before you start riding down the road. So, how does a motorcycle cooling system work? A motorcycle cooling system works in two different ways: first is air cooling in which natural wind passes through fins that are on the cylinder and cylinder heads. The second is through water cooling in which coolant passes through thin plates on a radiator that is cooled through natural wind and recirculated into the engine. The cooling system on a motorcycle is a pretty simple process but can have terrible consequences when it does not work right. This article can explain in detail exactly how the cooling system works on a motorcycle as well as other information you will want to know as a rider. Air cooling is the most common way for a motorcycle to cool itself down. Most motorcycles will have this. It's efficient in a sense that it requires less parts to complete the cooling down of an engine. You will notice how a lot of motorcycle will have ridges, or fins, on the engine. These are not simply for looks, they actually serve a vital purpose in the functionality of the motorcycle (though they do look pretty cool!). The combustion process inside an engine is extremely hot and it needs to be in order for the engine to move those pistons up and down to make the motorcycle move. But the engine can not get too hot because that will mean the structure of the metal components will begin to change and in turn can ruin the engine entirely. You may have heard the term "a seized engine." This means the pistons inside have somehow fused to the cylinder walls; this is usually because those parts got way to hot and essentially melted together. The engine is basically totaled when this happens. It's possible to get it fixed but it's probably more economic to simply get a new engine entirely. This is where those fins come into play. Most of the parts on a motorcycle are exposed anyway, so placing fins on the cylinder and cylinder head is a perfect way to cool down the engine. These fins are generally made from aluminum because it's light weight and has a higher heat transfer efficiency. While riding a motorcycle down the road, wind will naturally pass through these fins and will essentially cool down the engine. The engine would not be able to cool itself down as efficiently without the fins; the structure of the fins can catch air much better than the engine block itself. The way a water cooling system works on a motorcycle has the same principle as air cooling but is performed differently. You will notice that a water cooled motorcycle engine looks a little different than others. This is because these types of bikes usually do not have fins, instead they have what is called a radiator likely placed at the front of the engine block. This is a more complex system but can withstand more extreme temperatures. Instead of fins on the outside, there are trails called water jackets that are inside the engine and around the cylinders. Attached to these trails is a radiator as well as a reservoir. A pump (known as the water pump) circulates and pushes a water/antifreeze solution from the water jackets inside the engine to the radiator then back into the engine. This coolant is passed through small plates during radiator circulation which essentially cools it down due to the wind passing through it. Then the cooled down substance is then recirculated throughout the engine to cool it down. The thermostat plays a vital role because it senses the temperature of the engine and regulates how much coolant passes through the engine as needed. An extra fan is placed by the radiator and is turned on as a backup in case the coolant is not cooling down the engine fast enough. A reservoir also plays a vital role as extra coolant is placed there through pressure in the case the radiator needs it. Though this method is commonly referred to as "water cooled," it's not just water that circulates throughout the engine. A 50/50 mixture of antifreeze and water is needed for optimal temperature control; the antifreeze has a higher tolerance for both freezing and extremely hot temperatures so you do not have to worry much about riding your motorcycle in either condition. Plain water in a system like this gives it less tolerance and can overheat your engine. Which One Is Better? One common question you will hear in the motorcycle world is "Which cooling system is better?" There really is no right answer for this, it's all just based on the rider and their preference. I can go through a pros and cons list of each and let you decide which motorcycle cooling system works for you. First we will discuss air cooling. One of the biggest advantages of a system like this is it's simplicity. Really the only parts that go along with this is the fins and that's basically it. That means no coolant leaks and there's less parts to maintain which means it's cheaper, too. Because of the simplicity of this system, your engine will warm up much faster when you are trying to go for a ride. You do not have to wait for the coolant to circulate and do it's thing before reaching optimal operating temperature. The biggest disadvantage of having an air cooling system is that it's less efficient compared to a water cooling system. This, in turn, means you will have a higher risk of overheating the engine which could mean costly repairs later on. Though the system is much less complex, the fins on the engine can be a complicated fix if enough of them are broken. A chip here or there is not much of a worry, but a hard impact or drop with several fins broken could mean you need a new cylinder head or cylinder covers altogether. How about the advantages of water cooling? Water cooling is essentially much more efficient with how it regulates temperature of a motorcycle engine. The regular heat transfer it's constantly performing can assure a rider that their motorcycle is much less likely to overheat, especially if they are riding a sports bike or using it for commuting. Unlike air cooled, water cooled engines do have a lot of parts that you will have to take care of and maintain. This system is obviously much more complex than an air cooled system, so there could be several culprits as to why an engine overheats if you find yourself on the side of the road with one. You will also need to stay on top of coolant levels; forgetting to top it off or letting it dissipate through constant cycling could also mean an overheated engine. Not to mention the possible coolant leaks you could encounter that can be sometimes difficult to pinpoint as to where they are coming from. I have owned both water cooled and air cooled motorcycles. Air cooled is much easier to come by since most motorcycles are built this way and it's what I personally prefer because of the simple maintenance. It's really up to you and what you are okay dealing with on your motorcycle. What Causes A Cooling System To Malfunction? Part of knowing how a cooling system works on a motorcycle is understanding what can go wrong with it and what causes it to do so. If you find yourself with a motorcycle that's constantly overheating, here's what the problems may be. We've touched up on the fact that several broken fins on an air cooled engine can cause it to overheat. We've also covered that not staying on top of coolant levels of a water cooled engine can also cause the engine to overheat. But there are several other ways an engine can get way too hot no matter what type of engine you have. A lot of people do not realize that oil has a lot to do with the cooling system. You could have all the coolant or wind you need to cool down the engine, but if there's not enough oil the engine can still overheat and seize. The lubricating properties oil has helps the cooling system keep the engine at a lower temperature. Be sure to stay on top of oil changes because that has a lot to do with engine health, too. High revs or a high idle can also cause the engine to overheat. Conditions like these means the engine is working overtime. You can compare this to the way you exercise; the more cardio you perform, the hotter and more sweaty you get. An engine works in a similar manner. It's okay to rev your engine, but if you are constantly revving it you risk getting into that overheating stage (see my other article here to learn more about revving your motorcycle engine). If you notice your motorcycle is idling high unintentionally, you may need to adjust the idle screw on the carburetor. A normal idle should be between 700-1,000 RPM's; anything above 1,500 RPM's is excessive. Click here to see my other article to learn more about why your motorcycle may be idling high. Having an overheated motorcycle engine can be frustrating and expensive. But it happens to most of us riders and sometimes can not be prevented because of some other underlying issues. To learn more about how to prevent your motorcycle from overheating, see my other article by clicking here.
Why Is My Car Overheating with New Cooling System?
Why Is My Car Overheating with New Cooling System?
check your coolant amount, most times after a repair like this, the coolant amount, is off, because of time-lapse continuity, every morning for the next few days, check your coolant level, if anything else then do what the other dude says''1. Is a laptop supposed to smell after you replace the cooling system?Does the cooling fan run ? That is the only cooling for a laptop is the fan. Are the cooling vents clear of dust and lint ? No a new cooling fan should not have any smell especially like burning plastic. If a new laptop does not smell like it is burning then one after replacing a fan should not smell like it is burning.2. Having some trouble witht liquid cooling system for computer (funny noises??)?I would try filling your bathtub with water and have a helper hold your head under until the bubbles stop3. how do you get air out of cooling system of ford contur 1999 4 cylinder eng.?Disconect the top Radiator hose and crank Eng.Kill eng when water comes out; I worked on a S-10 that had a rad leak this p.u. had been filled so many times ;It had an Air Lock-The solution above was what I did.4. How many gallons of distilled water does it take to completely drain all the coolant out of the cooling system?if you keep puting it in it will keep comeing out5. Radiator cap pressure and how it impacts stress on cooling-system and engine?First, you should not put a higher pressure cap on your cooling system than what it's designed for, that way there will be no issue in the first place.That said, yes, there will be slightly more stress on the components. The part which will most likely take the brunt are the rubber parts because they are the most flexible. As long as they can take it, there wo not be an issue (if all we are talking about is a couple pounds of pressure). There is something you really are not taking into account, though, and this has to do with heat. Remember, it is not the coolant which dictates the heat, the thermostat does. It will be unaffected by more pressure in the system. It will still open when the temperature gets to a certain level and close when it comes back down. More pressure does not necessarily equate to more heat. The other thing is, under lower pressure, pockets of steam can still form in certain hot spots. With a higher pressure, these pockets will be less likely to form or the pockets will be smaller. This means more coolant is touching more of the block/heads, which means the coolant can do a better job of cooling.6. Back again with my 94 fullsize Chevy Blazer "Tonite for one nite only 'The Cooling System'!!!!"I am sure there's a question in there somewhere...??7. How do you bleed the air out of the cooling system on a 2002 Pontiac Sunfire?Recharging the AC device is not annoying yet whilst that save can not locate the leak then you definately could desire to have it regarded at someplace else. If the dye can not be stumbled on leaking decrease than the hood then there is only another place it is leaking thats in the sprint. it could have a leak in the evaporator center. Take it to a save that knows what they are doing or save spending greater undesirable money8. What's wrong with my car's cooling system?Experience the same with a Neon. Turned out to be a hairline crack between the head coolant port to the valve chamber on cylinder #2. On another occasion, the coolant cap seal was broken, allowing coolant to seep out and when the motor would cool down, the level remain the same in the reservoir. maintenance for 25 years9. what causes preasure in the cooling system?Nope -- high pressure signals warm weather, low pressure brings cold weather. Think of it this way: if the pressure is low, it means cold air (which is denser, thicker than warm air) has to flow in to even things out. When the pressure is high, it means the cold air is pushed away. And cold air is thicker because any gas is compressed at lower temperatures. In a room or car, for example, the colder air falls to the bottom and the hot air rises to the ceiling. same thing goes for steam on your coffee.
Why Don't I Have Heat in My Car?
Why Don't I Have Heat in My Car?
Why don't I have heat in my car?Have you made sure the coolant return tank is filled to the proper level? It helps get the air out of the cooling system. Did you get the right pressure cap? Make sure you put in a 195 degree thermostat. You might have also gotten a defective thermostat. Did you get suckered into buying a safety stat thermostat? I've found that those things generally open once and never close and can cause the same thing you are describing. Some of today's newer engines have bleeders in the cooling system to help get the air out of the system. Also check the heater control valve to make sure it is opening all the way.— — — — — —Can someone help me with this question ????A reactor creates energy by heating up water into steam and driving a turbine. Therefore, its job is to produce heat. However, too much heat will melt and destroy the reactor. So, the first part of the cooling system would be the water (steam) that generates the electricity. More cooling water would be used if the reaction gets too energetic and the standard amount of water is not enough to cool the reactor down (may happen at night when demand for power is lower, but the reactor always produces heat). The reactor heating this extra water would be wasted energy, as it is only being used to cool the reactor and not generate power. Finally, control rods made of lead and other dense materials are lowered between radioactive materials to shield them from each other, thus slowing the nuclear chain reaction and cooling down the entire system.— — — — — —My 03 Jetta is overheating even though the antifreeze container is full?First of all, if the container is not low, you do not have a leak. But never put in pure water, because all the aluminum parts will quickly corrode. Second is that you need to decide if the cooling system is not working right, or if something major is making it get way too hot. First you need to decide if the thermostat is opening or not. Start a cold engine, and feel both main hoses to the radiator. The top one should slowly get warm, while the bottom one should stay cold until the engine gauge gets to normal, and then it should instantly open and get as hot as the other. If it does not open, then the thermostat is bad and need replacement. Second thing to check is that if you let it idle long enough, the electric fan should come on. It it does not, it could be a fuse, relay, temperature sensor in the radiator, or the fan motor itself. Relays are the most common problem. Pump up the pressure and see if it holds. They start the engine, rev it, and watch for oscillations in pressure.— — — — — —Is it normal for my car to do this?This temperature gauge fluctuation is a common symptom of a blown head gasket.Get a compression or cylinder leak down test performed. ADDITIONAL: a malfunctioning or "sticking" thermostat will not produce a fluctuating gauge,usually a bad thermostat will either be stuck open or closed,in which case will manifest a cold condition with the system not reaching operating temperature or an over heating system,but not both.The fluctuation in the case of a blown head gasket is caused by exhaust gasses entering the cooling system and pressurising the system rapidly causing the thermostat to open and close repeatedly.Trust me I have seen this many times before.— — — — — —no heat in my 1994 transport van when idling?flush the cooling system. Check for a kinked heater hose. Back flush heatercore— — — — — —I have a 2002 Chevy Malibu, coolant light is still on after fixing, What else could be wrong with it?did the bleed the air out of the cooling system ? with air in the system it can,t circulate !— — — — — —Can You Help Me Please?If it's a standard gas furnace with an attached split (coil inside, evaporator/compressor outside) system, you should be able to simply shut off the gas valve and use the cooling system. These systems are attached to a gas furnace so you can use the air handler (fan) and attached ducts for both heating and cooling. If you want to use the heating system in the winter you will have to turn the gas back on and make sure the furnace works properly.
I Have a 99 Pontiac Sunfire and the Cooling Fan Quit Working and the Fuses Are All Fine,?
I Have a 99 Pontiac Sunfire and the Cooling Fan Quit Working and the Fuses Are All Fine,?
A new fan motor is in the neighborhood of $50. With simple tools just about anyone can fix it. Buy a Chilton's Car repair manual for your Sunfire. It's about a quarter the cost of one hour of labor at the dealer's service department. The book will walk you through every minor and major repair job on the car. Anyhow, before you run out and buy a new fan, there may be what is called a fuseable link somewhere in the actual fan circuit that has blown. Check the electrical connection at the fan itself. Good luck!1. Does anyone know of a good CPU cooling fan?arctic freezer 7 pro , im using it on my Q6600 clocked at 3.4 gig and its perfect , it also comes with good heat sink paste but if you want to be really picky get yourself some arctic silver 52. 1998 Honda Civic EX Cooling fan not coming on?Use the 87 octane...the guy that mentioned he gets extra suitable gas mileage by ability of utilising top classification is not telling the fact. top classification gas has no experts whilst used in a automobile that throughout the time of basic terms desires 87. it is likewise a minimum of 20 cents extra consistent with gallon. ...which equals approximately $2. 50-$3 consistent with top off. ...That provides up in hurry in case you utilize plenty gas3. Best Air cooling fan for my cpu?You have to choose the type that fits your CPU. You can not choose any types you want4. if your cooling fan runs all the time and you drive your vehicle with the headlights on?Depends on the output rating and condition of your alternator and the reserve capacity ampere/hour rating of your battery, but should not be a problem especially with engine running at its highway speed RPM range (2-3K)5. why do laptops get hot even though they got a cooling fan?BECAUSE UR ON IT AND THEY ARE RUNNING and it makes it hot like how we sweeaat and we drik water but we still sweat after so thats y6. what happen if PC is switched on without cooling fan placed on the CPU? Will it burst or just goes OFF?IF your PC is of good quality it will simply shut down when it heats up. However if it is not it will over heat your mother board and processor rendering them useless. Fans are very cheap so I would recommend replacing it.7. USB Cooling Fan Won't Turn Off When Laptop Sleeps?It just means the 5 Volt rail in the netbook is still live. Nothing you can do about that. USB fans connect to the USB socket simply to get the 5Volt supply, there is no other control via that socket so if the 5Volt rail does not close down then the fan will still run.8. where is the relay for a 99 ford escort cooling fan located?Under the plastic strip above the radiator, it is a relay control box that controls many components, kinda spendy but buy new as they fail often9. cooling fan stays on after engine is shut off?It's safe to drive but you should check the wiring going to the coolant temperature sensor. Sounds like the sensor is unplugged. Is your check engine light or service engine soon light on? If so I would bet you have a code for the coolant temperature sensor. Hope that helps! Jim10. How to deliberately activate cooling fan of laptop?I would look at the sys devices directory. For example, in Sony Vaio laptops, you can turn on the fan to max speed with this command:In your laptop, try doing a:or manually inspect the directory using tree, looking for something that refers to fan speed:11. How long CPU Cooling Fan is suposed to last ?CPU fans will last as long as their hardware lasts. That could be 3-5 years or even more. When they start making noise and do not spin as fast or if your CPU gets too hot and the PC shuts down, you may want to replace the CPU fan. I've built computers for many years and replacing CPU fans usually is not an issue. Even the cheaper ones last a long time. Worst case scenario-CPU fan fails, CPU heats up, computer shuts down automatically so it wo not burn up.
Disassembly of Surface Laptop: the Best Way to Repair Surface Laptop Is to Replace It
Disassembly of Surface Laptop: the Best Way to Repair Surface Laptop Is to Replace It
Last month, Microsoft's unusual use of surface laptop made many people see the dawn of replacing old MacBook Air. However, for those who intend to personally upgrade and replace accessories and extend the service life of surface laptop in the future, this is bad news. Ifixit's disassembly of the notebook shows that a large amount of glue is used, and the shell without any screw holes The hardware welded to the motherboard did not consider any maintenance at all.The disassembly team first turned over the bottom of the notebook to find a breakthrough under the four rubber foot pads, but the exposed piece of metal forced them to find another way.The Alcantara material on the C surface seems to be a good idea, but when trying to remove it, it encountered difficulties, resulting in an art knife. These people feel that they encountered the use of adhesive at the beginning. I'm afraid nothing good will happen next. This notebook will be taken apart and don't want to put it back.Pry open the metal shield of the wrist support of the surface laptop, remove its keyboard, and finally see the interior of the notebook. By the way, take a look at the keyboard. It is as difficult as the fabric on it. To remove it, you have to pry a protective cover on the motherboard to pull out the cable.In contrast, the touch panel on the keyboard is easier to remove. Remove the black tape and screw off the fixing screws with a screwdriver to remove the touch panel from the outside. There are two chips on the internal PCB of the touch board, the master of NXP mk22fn512 MCU and Synaptics s9101b (the same as that on the surface book).Looking back at the internal hardware of the notebook, the disassembly team wanted to remove the battery occupying half the space first, but after looking for a circle, they didn't find the battery cable, so they had to start from the motherboard first. First, remove the speaker, remove the antenna on the right side of the fuselage, and then remove the metal shield attached to the heat sink, and the motherboard will show its real body.However, under the condition that all hardware configurations have long been known, the chips on the motherboard must not look new: in the red box are core i7-7660u, in the orange box are four lpddr3 particles of SK Hynix, in the yellow box are Toshiba thnsnd256gta 256gb SSD, in the green box are Marvell avastar 88w8897 WiFi Bluetooth NFC three in one Wireless SoC Microsoft's display driver IC is in the water blue frame, and Nuvoton TPM chip is in the blue frame. There is also an NXP MCU on the back of the motherboard. All chips are directly welded on the motherboard, and there is no possibility of manual disassembly and replacement.After removing the motherboard, the 45.2wh battery was "disassembled" in a sense. There is also a heat conducting pipe on the back of the motherboard to help heat the core hardware of the notebook. Finally, the audio jack is a modular design, but there are too many destructive operations in the previous disassembly process, so there is no objection to its disassembly and replacement.After removing the hinge connecting the cable to the display, the ifixit team ended the self maintainability evaluation of the surface laptop and gave it a generous 0 point. We can conclude that this notebook is not only broken, but can only be sent for repair and replacement. When you buy it, you must be in place in one step. If you find that it is not enough after buying the beggar version, there will be no regret medicine to eat.

You've come to the right place. Portable air conditioners are great for those who do not have a central AC system or want to save on energy bills by only cooling the room in use. A portable AC uses less energy than a central room air conditioner and is more versatile since you can move it from room to room. But the term 'portable AC' can be misleading. Some portable ACs weigh 80 lbs or more and require semi-permanent ventilation - making it next to impossible to move, once installed. But let's be honest: for most homes and most rooms, a small portable air conditioner is all you need. Even better, smaller portable AC units cost a lot less, work in more rooms, and are truly portable. Why Smaller is (Usually) Better The bigger a portable conditioner is, the more powerful it is, meaning it will cool a space faster. But a large portable AC is not always the best choice for cooling a room. If it is too big (in terms of BTUs) for the room you are using it in, it can actually make the environment more uncomfortable. According to the Department of Energy, a too-large AC is inefficient at both cooling and dehumidification. It will leave the room feeling clammy and uncomfortable. A smaller AC unit that's matched to the room size cools and dehumidifies more effectively and operates using less power. In addition to the energy-saving and better cooling performance, a small AC takes up less space and is easier to move from room to room. Choosing the Best Small Portable AC for Your Home Pay attention to the BTUs of the portable AC you plan to buy. Portable air conditioners typically start at 5,500 BTUs. This is ideal for small rooms of up to 150 square feet. Most homes will find an 8,000-BTU portable AC to be the best. It can cool a room of up to 350 sq. Ft. Of course, a small portable AC is not always the best choice. If you have fairly large rooms at home, you do not want to get an underpowered AC. It will waste as much power as an oversized one as it attempts to cool the entire room. So, depending on your room size, you may need to go up to 10,000 BTUs or 14,000 BTUs. For a complete AC sizing guide, see the sizing table below the reviews. The BLACK DECKER BPACT08WT portable AC is rated at 8,000 BTUs, which feels like it should be able to cool a room larger than the 100-150 sq. Ft. The manufacturer recommends. But, perhaps because of some design feature, Black Decker recommends it for small rooms only. The upside of having more BTUs is that it cools the room fast, faster than most other portable ACs. This is especially noticeable on hot days. You will feel the difference in just a few minutes after switching it on. Not only does it cool fast, but it also cools evenly. This is because air moves in a vertical motion as it comes out of the vents. So instead of cooling only one side of the room, it is spread out everywhere. You can select from four fan speed setting. High: Fan spins fastest to distribute more cooling air and lower the room temperature faster. The AC gets somewhat noisy at this setting. Med: Balances between performance and noise level. This setting is ideal for maintaining the room at a certain temperature. Low: The slowest fan speed. Ideal for colder days or at night when you want to reduce the noise level. Auto: The AC will automatically select the best fan speed to achieve the set temperature. For convenience, leave it in this mode. This is a 3-in-1 portable air conditioner: cooling, fan-only, and dehumidification. The built-in dehumidifier reduces moisture in the air though Black Decker does not specify its dehumidification capacity (the amount of moisture it can extract from the air per day). When it extracts excess moisture from the air, it has to take it somewhere. In some portable ACs, you have to set up a drainage system to collect the water. You do not need to do that with the BLACK DECKER BPACT08WT. It has an auto-evaporation feature. It exhausts hot air from the room along with moisture. However, on particularly humid days or if you turn on the dehumidification feature for a prolonged period, the moisture may be too much for the AC to auto-evaporate. You will need to drain the AC occasionally to remove excess condensation. The control panel will alert you when the internal reservoir fills up. But in most cases, the auto-evaporation feature is enough, saving you the trouble of connecting a drain hose or using a bucket. The BLACK DECKER BPACT08WT comes with a complete window kit that includes a hose (max length - 4'11"), inlet and outlet adapters for the hose and an adjustable window bracket. The window kit works with both vertical and horizontal slider windows. You can also install it to vent through a sliding door. The window kit is super easy to install. You do not need to screw anything. Just fit the bracket into the window and close the window. That should hold it tight in place. If you need to use the AC in another room, it's easy to take it down. Cool: This is the cooling mode. You can set a target temperature anywhere between 62F and 86F and select your desired fan speed. Dry: This is the dehumidification mode. You can set your desired humidity level, but you cannot change temperature or fan speed. The unit will operate at a low fan speed until the room has been dehumidified. Fan: If you only want mild cooling, the fan mode is ideal. It turns off AC cooling, leaving only the fan to circulate air in the room gently. Auto mode: In this mode, the unit will select the right mode (between cool and fan) and fan speed based on the target temperature you've selected. There's no limit to the size of the room you can dehumidify with the hOmeLabs portable AC. It can dehumidify any space from a small home office to an open style loft apartment. According to the manufacturer, it's good for any space up to 5,500 square feet. But remember that that's only for dehumidification. For cooling, the limit is 600 square feet. If you want to dehumidify a large space, make sure you've selected the DRY mode. You also need to connect the drain line to the port at the back. The AC does not have a built-in reservoir. So continuous drainage is a must. The drainage is gravity-fed so ensure you direct the hose somewhere where the water will flow easily on its own. The drain port is located in the middle of the unit at the back. So you can easily direct the water to drain in a pan or bucket on the floor. In dehumidification (Dry) mode, you cannot select temperature or fan speed. But you can select your preferred humidity level. The unit will operate at the lowest fan speed until it achieves the target humidity level. The hOmeLabs AC comes with a complete window kit that is easy to set up. The kit includes window sliders, the exhaust hose, foam seals and adaptors. The two window sliders can be adjusted to fit windows between 26.5" and 48" wide (or high, if you have vertical sliding windows). If your window is smaller than 26.5", you can cut one of the sliders to fit. Unlike most ACs, the hOmeLabs includes foam adhesives that you place around the window frame for an airtight fit. This prevents outdoor air or warm exhaust air from coming into the room. Most customers said it took them less than 10 minutes to have the window kit set up. It's also easy to take it down when you want to use the AC in another room. Note: You do not need to set up the window kit when using the DRY mode. Do I have to vent a portable AC out of the window? A portable AC needs ventilation to release heat outside. The window is the easiest and the most convenient place to vent the AC. But if the room does not have a window or you have a non-compatible window (portable ACs work only with sliding windows), you can set it up to vent through a sliding door, a hole in the wall leading outside or into the garage or through a drop ceiling. These alternatives will require a bit of DIY-ing to work, and you may face some limitations depending on where you live. Are there portable air conditioners without exhaust? Evaporative air conditioners, also called swamp coolers, do not have any exhaust. They work by introducing moisture-cooled air into the room rather than extracting heat. So you do not need to set up any venting. Is a portable AC as good as a window unit? A portable AC uses slightly more energy than a window AC, but it works just as well. Of course, you have to make sure you select the right size (in BTUs) for the room. A portable AC has several advantages over a window unit. It is easier to install (requires no installation really; just ventilation). Besides this, it is easier to move to another room, and operate more quietly than a window AC. It depends on the size of the AC, its efficiency, room size, and temperature. A higher BTU AC will use more energy. An air conditioner cooling a large room or working in hot weather will also use more power since it has to work harder. Generally, it costs about $2.84 a day to run a small compact AC for 8 hours a day. A larger unit will cost anywhere between $3 and $6. To get more accurate figures, check the wattage of the AC. Multiply that by the average number of hours you will be using it per day and then divide the result by 1,000 to get the daily consumption in kilowatt-hours. Multiply that with the unit cost of a kWh your utility charges to see how much the AC costs to run per day. Note: To reduce consumption, look for ACs with energy-saving features such as auto mode and eco mode. Do portable air conditioners need to be drained? If your air conditioner is self-evaporative, you wo not need to drain it during normal use. It will exhaust moisture out of the window together with the hot air. But if there is a lot of humidity, you may need to connect a hose to the drain port to remove the condensate. Some ACs do not have a self-evaporative feature. You have to keep a drain hose connected all the time. Not really, unless you live in an open style loft apartment with no dividing walls. In a normal home, even if you buy a powerful 14,000 BTU air conditioner, the fan can not move the air efficiently to all rooms. If you need constant cooling in different rooms, consider buying two or three smaller portable ACs instead of one big one. Most portable ACs sound like a desktop fan. But the noise level depends on the design and quality of the AC. Some brands are quieter than others. If the AC is too loud, select lower fan speed. It will take longer to cool the room, but it will be quieter. Which is the lightest portable AC in our buying guide? The Honeywell MO08CESWK is the lightest portable AC in our buying guide, weighing 43lbs. The Evapolar evaCHILL is the lightest swamp cooler we've reviewed at just 2.78lbs. At the lower end, small portable ACs designed for small rooms cost between $200 and $350. Larger units that can cool a medium-size room cost between $350 and $500. High-end portable ACs cost around $500 to $700. These units have more cooling power and high dehumidifying capacity. If you are looking for a swamp cooler, you can get a good-sized unit for under $200 and mini personal coolers for less than $100.
