Car air conditioning function: create a suitable environment for the human body by artificial means, that is, adjust the temperature, humidity, airflow speed in the car, and have the function of purifying the air. Automobile air conditioning components: refrigeration system, heating system, ventilation system, control and control system, air purification system Refrigeration system: the use of vapor compression refrigeration, the air in the car to cool. As a cold source of the evaporator, the temperature of the air dew point temperature, therefore, the refrigeration system also has the effect of dehumidification and purification of the air.
Heating system: By introducing the cooling water of the engine into the heater, the air is heated by the blower, and the front windshield defrosting ventilation system can also be used: including the blower, air duct, damper and outlet, etc., the damper introduces the fresh air outside the car into the car, and the dirty air inside the car is discharged out of the car through the exhaust outlet. Control system: the general electrical system, vacuum system and control device composition, the refrigeration system and heating system control at the same time, the air temperature, air volume, flow in the car to ensure the normal operation of the air conditioning system.
