What are the main aspects of automobile air conditioning?

The air conditioning of Pacific Auto Network automobile air conditioning mainly includes refrigeration device, heating device and ventilation device. The main function of air conditioning is to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, to provide a comfortable riding environment for passengers, to reduce travel fatigue and to create good working conditions for drivers, which plays an important role in ensuring safe driving.

The air conditioning in the car is the air conditioning system of the car. The air conditioning system can adjust the air temperature inside the car and filter some dirty things in the air outside the car.

In-car air conditioning is the standard configuration of all cars. The air conditioning system can adjust the temperature, humidity, wind speed and ventilation. The air conditioner in the car has the function of external circulation, which can achieve the function of ventilation. Moreover, the air conditioning filter element can filter some dust, pollen, pm2.5 and so on in the outside air.

Air conditioners can blow cold air or hot air. The hot air of air conditioner uses the temperature of engine coolant. When the heating function is turned on, the coolant of the car will be introduced into the heating water tank, and then there is a fan behind the heating water tank, which can blow out hot air.

Automobile refrigeration depends on compressor. After pressing the ac key, the compressor clutch is engaged, and the engine drives the compressor to rotate, so that the compressor compresses the refrigerant, and then the compressed refrigerant finally reaches the expansion valve to expand, and then enters the evaporation box. Automobile air conditioner relies on the volume expansion and heat absorption of refrigerant to refrigerate. At present, most refrigeration media use r 134a.

The condenser of the air conditioner is located in front of the car water tank. After the refrigeration function of the air conditioner is turned on, the electronic fan will also rotate to cool the air conditioner condenser.

The filtering function of air conditioner depends on the filter element of air conditioner. The air conditioning filter element is generally located behind the glove box of the co-pilot.
