What is the reason for the air conditioner to blow hot air? What happens when the air from the air c

1. The air conditioner is not working, because the temperature of your room is already high, and the wind blowing out of the external unit is no different from the electric fan, and many people will mistakenly think that it is hot air.

2. If the air conditioner is a cold and warm type of external unit, the four-way valve should be channeled, or the mainboard of the internal unit is mistakenly powered to the four-way valve coil, which will cause the internal unit to blow hot air.

Air conditioner is the abbreviation of air conditioner, air conditioner is the equipment that processes the temperature, humidity, purity and airflow speed of the air to meet the needs of people's production and life. Hanging air conditioner is one of the types of air conditioner, which is used to provide a unit to deal with air temperature changes in a space area that saves space (usually closed).

Its function is to adjust the parameters such as temperature, humidity, cleanliness and air flow rate of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process, but the size of the air conditioner should be selected according to the size of the space.

There are many types of household air conditioners, including wall-mounted air conditioners, cabinet air conditioners, window air conditioners and ceiling air conditioners, but these products have their own characteristics, and they are also different, so they should be selected according to their own needs.

Summer is coming, what should I do if the air conditioner always blows hot air? @玩车女神 @抖音汽车 Know how to drive.

There are several possibilities that the air blown out of the air conditioner is hot air: the first is that you can adjust the mode of the remote control to the heating mode, and change it back to solve the problem. The second possibility is that the four-way directional valve is broken and cannot be reset.

If there is a lot of noise in the pipeline during the process of heating to cooling, it means that the four-way directional valve is working normally. It may be that the air conditioner leaks fluorine, and the pipes are not connected properly when moving the machine, resulting in fluorine leakage and poor refrigeration effect. You can check if the pipes are ruptured.

The third possibility is that the motherboard of the internal unit mistakenly supplies power to the four-way valve coil, causing the air conditioner to blow hot air.

If the air conditioner blows hot air, there are several possibilities, one is that the refrigeration mode is not turned on, the compressor is not working, and the other is that the compressor is not working due to problems with the refrigeration system, and the main reason is that the compressor is not working.

There are several possibilities for the air conditioner to blow hot air:

The first is that it is possible to adjust the mode of the remote control incorrectly, and change it to the heating mode, and change it back to solve the problem.

The second possibility is that the four-way reversing valve is broken, can not be reset, if there is a big noise in the pipe during the heating conversion refrigeration, it means that the four-way reversing valve is working normally, it may be that the air conditioner is leaking fluorine, the pipeline is not connected well when moving, resulting in fluorine leakage, the refrigeration effect is not good, you can check whether the pipe is broken.

The third possibility is that the motherboard of the internal unit is mispowered to the four-way valve coil, causing the air conditioner to blow hot air.

Problems with the electronic control system, confusion in hot and cold modes.

The temperature sensor fails, and the protection against overcooling and overheating is ineffective.

There is a problem with electric heating.

The quality of the product itself.

Air conditioner open refrigeration hot air solution:

1) There are many reasons that cause the air conditioning compressor to stop running, such as refrigerant leakage, outdoor fan capacitor aging, compressor capacitance aging, outdoor fan motor failure, compressor failure, indoor fan motor or capacitor failure, air conditioning main control electrical component failure, outdoor unit heat exchanger is too dirty, ventilation around the outdoor unit is not smooth, etc., these possible reasons will lead to the air conditioning compressor can not operate normally. When this phenomenon occurs, you can observe the operation status of the air conditioner for a long time, such as whether it is intermittent or continuous, etc., and then report to the maintenance company for repair, and send maintenance personnel to come to the site for maintenance.

2) There is a problem with the capillary or check valve of the air conditioner, and replacing the capillary or check valve can solve the problem that the air conditioner does not heat.

3) Replace the operation in order to deal with it effectively and properly, and the specific implementation details can be referred to by relevant personnel.

If the discharge is not the heating mode, either there is no fluorine and no refrigeration, or there is a problem with the compressor. Continuous air conditioner after-sales maintenance bar, general air conditioner warranty for five or six years.

It's that the air conditioner is not refrigerated, and it needs to be overhauled, so you can match it with whatever material you want, and it's good to repair it.

First of all, you have to make sure that the outdoor unit is operating properly, and whether the temperature in your room is too low? Because the temperature difference between the air conditioner and the return air is about 10 degrees, if the room temperature is too low, the air outlet temperature will not be high.

It should not have been adjusted to refrigeration or cold coal.

First, first check to see if your air conditioner is in cooling mode. If not, just turn on the cooling mode and the air conditioner will cool down. If yes, check it out further.

Second, confirm whether the air conditioner is a heating or cooling unit. If so, see if there is a problem with the four-way valve. Whether it is engaged in refrigeration.

Third, if the air conditioner is a single chiller, it is impossible to produce hot air. The worst is the wind that blows out of room temperature. At this time, it is necessary to see if there is any snow species. If you don't have one, add it.

Fourth, there is another situation that is more dangerous, that is, the heating pipe in the refrigeration and heater also works in the refrigeration situation, if this situation occurs, it should be eliminated as soon as possible, otherwise it is very dangerous.

According to the above situation, step by step, you will know what the cause of the hot air blown by your air conditioner cooling is, and make corresponding solutions.

In the summer, I believe that every parent's favorite thing is nothing more than two things, one is the refrigerator, and the other is the air conditioner. Especially the latter, in summer, I can't wait to stay in an air-conditioned room all day, eat sweet fruits, and watch charming TV series. There is nothing more comfortable than this.

But there are always unsatisfactory times, once the air conditioner is not cooling, blowing hot air is like the sky falling, irritable. So how can you prevent this from happening? What should I do if it happens?

1): Not enough freon (also known as "refrigerant" is not enough).

This is a normal situation, generally appears in the use of three to four years of old air conditioners, air conditioning is not completely not refrigerated, but the effect of refrigeration is not good enough, this is because the old air conditioners are used as freon refrigerant, long-term use will volatilize, in addition to improper installation caused by freon leakage and the machine itself problems.

Solution: Replenishing refrigerant can solve the problem of air conditioning not cooling.

2): The voltage of the power supply is not enough.

The power supply voltage is unstable, and it often fails to reach the normal voltage, especially during the peak of electricity consumption. Of course, this kind of problem is obviously not something that a skilled air conditioner maintenance master can solve, and we must start from the aspect of providing a stable voltage to solve the problem.

Solution: Maintain a normal supply voltage.

3): The power of the air conditioner is not enough to not refrigerate.

This is also one of the common reasons for not refrigerating, but there are many reasons for this kind of non-refrigeration, such as: small power air conditioning pipes in a large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed (such as doors and windows are wide open, etc.), or there is a heat source in the room (such as a lot of computers) of course, the glass room is also one of the heat sources, and so on.

Solution: Make the power of the air conditioner and the refrigeration capacity required by the space want to match; change the conditions of the environment in which it will be used; Increase the airtightness of the use environment; Reduce the heating source in the environment where the air conditioner is used to solve the problem of non-cooling.

4): The air conditioner is not refrigerated due to the high ambient temperature.

This kind of non-refrigeration situation is common in our outdoor unit installed in a relatively closed space or the temperature around the outdoor unit is too high, so it is extremely easy to cause the heat emitted by the radiator to flow away due to the lack of air circulation in the small space where the outdoor unit is located, so that the air conditioner is not refrigerated; There is also a common saying that when the outdoor temperature exceeds 43 degrees, most air conditioners are difficult to transfer indoor heat to the outside through the radiator of the outdoor unit, which will also cause the air conditioner to not refrigerate.

Solution: Change the use environment of the outdoor unit (move away from the high temperature environment or make the surrounding air of the outdoor unit more easily circulated).

There are several possibilities for the air conditioner to blow hot air: 1. Your remote control mode is wrong, just switch back from the new 2. The air conditioner is not working, because the temperature in your room is high, the outside unit is not working, and the wind blown out by the internal unit is no different from the electric fan, and many people will mistakenly think that it is hot air 3. If the air conditioner is a cold and warm type of external unit, the four-way valve should be channeled, or the main board of the internal unit is mistakenly powered to the four-way valve coil, which will cause the internal unit to blow hot air. Take the phenomenon you illustrate:

I have repaired a lot of the four-way valve blow-by air caused by the internal unit blowing hot air, which is rarely caused by the mispower supply of the motherboard of the internal machine.

The best way is to find an air conditioner maintenance master in time to check and carry out a repair, but you can also check whether the operation is in the hot air gear, if not, it is often the refrigerant leakage or the compressor is not working.

The reason why the air conditioner blows hot air is likely to be that there is no refrigerant, so you can ask the maintenance master to add refrigerant and check whether there are other problems with the air conditioner.

Of course, it's adjusted, but it's not that it can't be adjusted, you just adjust to this cold air and the temperature you can accept.

First of all, you need to see if you have chosen the right mold, not the heating mode. If you have the wrong model, ask a professional maintenance person to check the specific cause to see if there is a lack of refrigerant or a problem.

If the air conditioner is indeed adjusted to refrigeration, and there is still hot air, it means that there is a problem with the air conditioner, which is generally a lack of freon and needs to be re-added.

Or maybe there's something wrong with the refrigeration part.

The air conditioner blows hot air, which is adjusted to the heating function, and when he is adjusted to the refrigeration function, the air conditioner blows cold air.

The biggest possibility is that the freon has leaked, and the refrigeration effect cannot be achieved, so it would be good to add a little, especially the old machine, which is not working.

The situation of non-refrigeration is common when our outdoor unit is installed in a relatively closed space or the temperature around the outdoor unit is too high, so it is extremely easy to cause the heat dissipated by the radiator to not flow away due to the lack of air circulation in the small space where the outdoor unit is located, so that the air conditioner is not refrigerated; There is also a common saying that when the outdoor temperature exceeds 43 degrees, most air conditioners are difficult to transfer indoor heat to the outside through the radiator of the outdoor unit, which will also cause the air conditioner to not refrigerate.

Check whether the external unit is running, if not, first replace the starting capacitor, if not, consider the compressor damage.

You don't adjust to refrigeration, or you see if there is no refrigeration, and there is no refrigeration.

The following answers this question for you, in fact, the reason why the air conditioner does not cool the hot air is very simple, mainly because the operation is wrong, or the air conditioner lacks fluorine, so it is not refrigerated.

If it is not a mistake, then it is necessary to call someone to overhaul the air conditioner.

The air conditioner always blows hot air: first check whether it is set to heating mode; If not, it could be caused by a refrigerant leak.

The answer may be that there is a leak or insufficient refrigerant in the air conditioner, which can be solved by adding freon. The reason may be that the compressor capacitor of the air conditioner is damaged, which can be solved by replacing the compressor capacitor. The reason may be that the four-way valve of the air conditioner is broken, which can be solved by replacing the four-way valve.

The reason may be that the computer board of the air conditioner is broken, which can be solved by replacing the computer version. The reason may be that the air conditioner is set to heating mode, which can be solved by changing to cooling mode.

This should be considered whether the air conditioner in your home is broken or the heating function is turned on.

Reason: Due to the abnormal situation of the air conditioning system, the compressor stops running, only the outdoor fan and motor of the air conditioner are working, and the air conditioner at this time is like an ordinary fan. Workaround:

Contact a professional to visit your air conditioning system.

Air conditioning maintenance: remove debris from the vent to ensure normal ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the air vents unobstructed.

Indoor and outdoor heat exchanger surface cleaning to improve the efficiency of the heat exchanger. When cleaning the indoor heat exchanger, you should carefully remove the panel, scrub it with a soft rag, and use a small brush to gently scrub the heat exchanger of the internal machine, so as to achieve the purpose of removing dust and harmful accumulation of multiplying germs.

Clean the dust on the filter screen. When cleaning the filter, first cut off the power supply, and then open the air inlet grille; Take out the filter, wash the filter with water or a vacuum cleaner, the water temperature should not exceed 40 degrees, wash it with a hot damp cloth or neutral detergent, and then wipe it with a dry cloth, and do not wash the filter with insecticides or other chemical detergents.
