4hw.com.cn: one of the most common problems of air conditioning is that it doesn't cool. In the hot summer, if the air conditioner just rumbles and does not cool, do you feel very upset? Today, China warranty network talks about the reason why the air conditioner does not cool from the user's point of view. There are many reasons why the air conditioner doesn't cool. As a fan of home appliances and a user of air conditioner, I have seen and heard all kinds of reasons why the air conditioner doesn't cool. Now I'll list some of the most common cases of air conditioner doesn't cool from the perspective of use, for the reference of users who have such unpleasant experiences. Maybe you can find them here Air conditioning does not cool the real reason and solve!

Of course, before analyzing the reasons why the air conditioner does not cool, I think it is necessary for us to have a simple understanding of the principle of air conditioning cooling. Here is a simple and popular description of the principle of air conditioning cooling The principle of air conditioning system --- the compressor compresses a kind of low-pressure vapor state refrigerant and turns into high-pressure and high-temperature vapor body. After cooling through the condenser heat pipe of outdoor unit, it turns into high-pressure and low-temperature liquid. Then it flows to the indoor evaporator with stable pressure and flow through the control of certain devices. When the high-pressure and low-temperature liquid refrigerant meets the low-pressure environment in the evaporator, it will be cooled Evaporation is the vapor body, and this evaporation process will absorb a lot of heat energy (commonly known as refrigeration), and the low-pressure vapor refrigerant will flow into the outdoor compressor, so as to cycle for refrigeration. In fact, this is what we described in the book: the principle of air-conditioning refrigeration is that the compressor makes the physical change between the refrigerants and leads the indoor hot air out of the room, so as to reduce the indoor temperature.

One of the reasons why the air conditioner doesn't cool: insufficient Freon (commonly known as insufficient snow)
The second reason why the air conditioner doesn't cool: the voltage of the power supply is not enough
The third reason why the air conditioner doesn't cool: the power of the air conditioner is not enough, so it doesn't cool
The fourth reason of air conditioning not cooling: the external environment temperature is too high to cause the air conditioning not cooling
The fifth reason for the air conditioner not cooling: the air conditioner does not clean and maintain for a long time
The sixth reason of air conditioning not cooling: the copper pipe between outdoor unit and indoor unit is too long
The following describes the various details of the common causes of air conditioning uncooling: one of the causes of air conditioning uncooling: insufficient Freon (commonly known as insufficient snow)

Solution: adding snow seeds can solve the problem of air conditioning without refrigeration
This kind of uncooling is mostly caused by the air conditioner that has been used for three or four years. Most of it is also a normal phenomenon. It belongs to the normal consumption of air conditioner refrigerant (i.e. Freon or snow) due to long-term use. However, it only shows that the air conditioner does not have enough refrigeration compared with the previous normal situation, and it will not completely uncooled, because the pressure is not enough, and it will not be compared with the normal situation The constant value correlation is too far away. At this time, you just need to find a regular maintenance network to supplement it. Of course, some of them are due to the installation or the machine itself. This is a common and relatively easy to find reason, and it is relatively easy to deal with this kind of problem. Check the pressure with a pressure gauge. If it is not enough, add it.

The second reason why the air conditioner doesn't cool: the voltage of power supply is not enough
Solution: maintain the normal supply voltage.
I have met a user who always said that the air conditioner was not cool enough at home, but once they went to check it again, they found it was normal, and after checking it several times, they found no problem. Later, during an inspection, it was finally found that the power supply voltage there was unstable and often could not reach the normal voltage, especially during the peak power consumption. The performance of this problem is: when the voltage is normal, the space-time modulation cooling is also normal. When the voltage is unstable, it will affect that sometimes the air conditioner does not cool. Of course, this problem is obviously not a skilled air conditioning maintenance master can solve, we must start from providing a stable voltage to solve the problem.
