The composition of automobile air conditioning and heating systems

The circulation system of air conditioning is a circulation system composed of major components such as compressor, condenser, expansion valve, and evaporation box. The refrigerant circulates in the circulation system and takes away the heat in the car interior through the principle of heat transfer in the evaporation box to reduce the temperature.

The heating system and the air conditioning system have two different working principles. The heating system uses the temperature of the coolant in the engine cooling system and transfers the heat from the small heating water tank to the room through the blower. It is also due to the heat The transmission principle makes the cab warm. When the heater is turned on, there is no need to turn on the air conditioner, that is, the air conditioner compressor must be turned off. Therefore, turning on the heater will not affect engine power and gasoline consumption.
