The principle of temperature regulation of "pit father"
If your car has a fixed displacement compressor, it is most cost-effective to adjust the temperature to the lowest when the air conditioner is turned on.
Because this kind of air conditioning system adjusts the temperature of the air outlet by controlling the mixed air volume. If you adjust the temperature to a higher level, the air conditioning system will send part of the cool air to the warm air tank for heating and then mix with the cold air, so that the air outlet temperature will not be so low, which actually wastes part of the cooling power. The variable displacement compressor can adjust the temperature by reducing the operating power of the compressor.
Therefore, for the fixed displacement compressor, the temperature is adjusted to the lowest and the most fuel-efficient. The variable displacement compressor is the higher the temperature adjustment, the more fuel-efficient.

What are the types of automobile air conditioning compressors?
The displacement of the fixed-displacement compressor increases proportionally with the increase of the engine speed. It cannot automatically change the power output according to the demand for refrigeration, and has a relatively large impact on the fuel consumption of the engine. Most of its adjustment is through collecting the temperature signal of the air outlet of the evaporator. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released and the compressor stops working.

The function and working principle of automobile air conditioning compressor
The automobile air-conditioning compressor is the "heart" of the automobile air-conditioning refrigeration system. Its function is to maintain the circulation of the refrigerant in the refrigeration system, suck in the low-temperature and low-pressure refrigerant vapor from the evaporator, and compress the refrigerant vapor to increase its pressure and temperature. The refrigerant vapor is delivered to the condenser.
