The main function of the air conditioner is cooling. She is the only one provided only by this type of equipment. You can heat, drain and filter the air using other units. But to what temperature does the air conditioner cool?
How the air conditioner cools
The cooling temperature of the air conditioner depends on the class of equipment and its price. But the cooling scheme is the same for all air conditioners. The cooling circuit of the air conditioner consists of a condenser, a compressor and a copper circuit. In the copper circuit, the refrigerant (freon) and some oil from the compressor are constantly moving in a circle.
From the evaporator, the refrigerant enters the compressor in the form of gas under reduced pressure (from 3 to 5 atmospheres) and a temperature of 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 also (15 - 20 degrees more than the air temperature around). Hot freon is supplied to the thermostatic valve, it is cooled here.
In the valve (a copper tube in the form of a spiral), the gaseous and liquid phases of the refrigerant are combined and fed to the evaporator. Now the refrigerant takes heat from the air, becomes gaseous and is again supplied to the compressor. This cycle repeats over and over. The cooling temperature of the air conditioner and the temperature of the air leaving the enclosure vary widely.
To what temperature does the air conditioner cool
Manufacturers laid the minimum temperature for cooling the air conditioner. Usually it is + 16 - 18 degrees. It is unlikely that anyone is pleased to be indoors at a lower temperature. To such extremals, welcome to the refrigerator.
By the way, the temperature of the air leaving the device varies between different models and under different temperature conditions from +4 to +16 degrees. The hotter the room, the higher will be the temperature at the exit of the housing. At start-up, the air conditioner cools the air weaker, and “accelerates” it 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 from 3.5 to 5 kilowatts of cold air for each kilowatt of electricity spent.
The higher the energy efficiency class of the appliance, the greater the difference between the amount of energy consumed and the temperature to which the air conditioner cools.
