The main function of the air conditioner is cooling. She is the only one provided only by this type of technology. It is possible to heat, dry and filter the air using other units. But to what temperature does the air conditioner cool?
How the air conditioner cools
Refrigerant enters the compressor from the evaporator in the form of gas under reduced pressure (from 3 to 5 atmospheres) and temperature from 10 to 20 degrees. Here it is compressed to 20 - 25 atmospheres, which leads to an increase in the temperature of the refrigerant to 75 - 90 degrees. And in this form it is fed to the capacitor.
Here, with the help of a fan, the temperature of the refrigerant is lowered, it becomes liquid and gives off heat to the surrounding air. Freon pressure rises, the temperature too (15 - 20 degrees more than the air temperature around). Hot freon is fed to the thermostatic valve, where it is cooled.
In the valve (copper tube in the form of a spiral), the gaseous and liquid phases of the refrigerant are combined and fed to the evaporator. The refrigerant now takes heat from the air, becomes gaseous, and is fed back to the compressor. This cycle repeats over and over. The cooling temperature of the air conditioner and the temperature of the air leaving the case differ significantly.
To what temperature does the air conditioner cool
The manufacturers have set the minimum cooling temperature for the air conditioner. Usually it is + 16 - 18 degrees. It is unlikely that anyone is pleased to be in a room at a lower temperature. Such extremals are welcome to the refrigerator.
By the way, the temperature of the air leaving the device fluctuates in different models and under different temperature conditions from +4 to +16 degrees. The hotter it is in the room, the higher the temperature will be when leaving the enclosure. When the air conditioner starts up, it cools the air weaker, and when it accelerates, it cools more.
In simpler and cheaper models, the temperature can be higher, more expensive air conditioners reach the minimum cooling temperature faster.
Being a fairly economical technique, air conditioners produce 3.5 to 5 kilowatts of cold air for every kilowatt of electricity consumed.
The higher the energy efficiency class of the device, the greater the difference between the amount of energy consumed and the temperature to which the air conditioner cools.
Hello. To what temperature should the air conditioner cool? I set it to 16-18 and the room temperature does not drop below 23-24 degrees. Although cold air is blowing from the air conditioner. What is the reason and is it necessary to call specialists?
Katya, the air conditioner may not be able to cope, it is designed for a smaller room area, the filters may be clogged, there may be little refrigerant
The same nonsense. I close one room and put it at 16 degrees. Lowers to a maximum of 23. And that's all. Room 4 by 3
I forgot to say, my air conditioner Samsung SH05ZZ8 AND SH05ZZ8X from +28 below +25 does not cool. This is normal?
no, it needs to be refueled
