What's wrong with the high temperature air conditioner not cooling? Introduce analysis and solution suggestions.

It's hot this summer, and many friends shut themselves in air-conditioned rooms all day. At this time, it can be said that it is very important whether the air conditioner can play a key role in refrigeration, but we find that many times the air conditioner does not seem to be able to effectively reduce the temperature, especially in some unbearable hot weather. Then, let's have a detailed understanding of the cause analysis, solutions and suggestions of high-temperature air conditioners in Bian Xiao, so as to determine a satisfactory maintenance scheme, or we can try our own operation, thus reducing the cost of manual installation and troubleshooting.

First, what is the problem that the high-temperature air conditioner does not cool?

Air conditioning aging

Generally, the service life of large household appliances is about 15 years. Although it is reported that some brands of air conditioners can still work normally after 20 years of use, this is actually rare. There will be many faults when the air conditioner is used over age, and even if it is repaired, it will continue to have problems.

Solution: Buy a new air conditioner.

Fluorine deficiency in air conditioning

A common reason why air conditioners don't cool is lack of fluorine, which is often called lack of snow seeds. If you find that the cooling effect of the air conditioner at home is not as good as before, it is probably because of insufficient or leaking refrigerant. Solution: Most of the reasons for this lack of refrigeration are the normal phenomena of air conditioners that have been used for three or four years. It belongs to the normal consumption of air-conditioning refrigerant (i.e. freon or snow) caused by long-term use, but this is only manifested in the fact that the air-conditioning is not cooled enough than before under normal conditions, and it will not be completely uncooled, because the pressure is not enough, and it will not be too far from the normal value. At this time, you just need to find a regular maintenance network to supplement it. Of course, there are also some snow species missing due to installation reasons or the machine itself, which is a common and easy reason to find, and this kind of problem is also easier to deal with. Check the pressure with a pressure gauge. If it's not enough, just add it.

Solution: fluoride

The power of the air conditioner is not enough

In order to save money, some friends bought an air conditioner with few people and put it in a big room. The air conditioning power with a small number of people is not enough. Although the air conditioning power seems to match the room area, the room is relatively closed, or there is a heat source (many computers) in the room. Of course, the glass room is also one of the heat sources, and so on. This situation is easy for us to ignore. If these reasons are found and handled properly, it will not only make the air conditioner cool, but also save electricity and prolong the service life of the air conditioner.

Solution: Generally speaking, only the number of air conditioners can be increased (to match the actually needed cooling area with the cooling area that can be controlled by air conditioning power); Change the conditions of the use environment; Increase the sealing of the use environment; Reduce the heat source in the air-conditioned environment and so on to solve the problem of no refrigeration.

The external ambient temperature is too high.

This kind of uncooled situation is common when our outdoor unit is installed in a relatively closed space or the temperature around the outdoor unit is too high, which will easily cause the air in the narrow space where the outdoor unit is located not to circulate, so that the heat emitted by the radiator cannot flow away, resulting in the uncooled air conditioner; There is also a common saying that when the outdoor temperature exceeds 43 degrees, it is difficult for most air conditioners to transfer the indoor heat to the outdoor through the radiator of the outdoor machine, which will also cause the air conditioner to be uncooled.

Solution: Change the use environment of the outdoor unit (away from high temperature environment or make the air around the outdoor unit easier to circulate).

Connecting copper tube is too long.

The long copper tube increases the transmission distance, which leads to the decrease of refrigeration effect of air conditioning.

Solution: Try to shorten the length of copper tube between outdoor unit and indoor unit of air conditioner.

Not cleaning and maintaining for a long time.

Because the outdoor unit is installed outdoors, it is easy to be ignored by everyone. After being used outdoors for a long time, a lot of dirt such as dust and dregs will be adsorbed on the radiator, which will make the radiator have poor heat dissipation effect and the air conditioner cannot cool. In addition, long-term use of air conditioners without cleaning and maintenance will lead to unsanitary indoor air, easily lead to air conditioning diseases, increase power consumption and shorten the service life of air conditioners.

Solution: Clean and maintain the air conditioner regularly.

The above examples illustrate the possible reasons why air conditioners can't achieve satisfactory refrigeration effect in high temperature weather and the corresponding solutions. It can be seen that the aging of air conditioners, excessive external temperature and other problems will lead to unsatisfactory advantages and characteristics of products. Further, we should also determine the corresponding reasons according to the actual situation, and if necessary, we can turn to professional maintenance agencies for operation. In addition, in order to reduce the labor cost, or reduce the loss and cost of waiting time, you can also refer to professional materials to try the operation yourself. For example, the above is of great reference significance, and I believe it is of reference significance to everyone.
