Car Dashboard Air Vents

With the development of the automobile industry and the improvement of people's living standards, more and more people begin to use cars, and the comfort of the car has also received more and more attention, and the air quality in the car greatly affects the ride. The importance of automotive air conditioning as a system to improve occupant comfort is becoming more and more prominent. Air Condition (AC) is a system that can adjust the air in the car.

The work of the air-conditioning refrigeration system is the process of continuous gasification and liquefaction of the refrigerant. Taking the center of the compressor and the expansion valve as the boundary, the entire refrigeration cycle can be divided into two parts: high and low pressure. The details can be understood from the above figure. The circulation process of refrigerant in the system can be divided into 4 working processes, as follows:

1. Compression. The low-temperature and low-pressure refrigerant gas processed by the evaporator is sucked by the compressor and compressed into high-temperature and high-pressure gas, which is then input to the condenser.

2. Condensation exothermic. The high-temperature and high-pressure refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid and releases a large amount of heat into the outside atmosphere.

3. Throttling. The refrigerant liquid with high temperature and pressure increases in volume after passing through the expansion device, and the pressure and temperature drop sharply, and it is discharged from the expansion valve in the form of mist (fine droplets). This is the boundary between high and low pressure of refrigerant, and the expansion valve has the function of throttling.

4. Evaporate. The mist refrigerant liquid enters the evaporator, so the boiling point of the refrigerant is much lower than the temperature in the evaporator, so the refrigerant liquid evaporates into a gas. During the evaporation process, a large amount of surrounding heat is absorbed, and then the low-temperature and low-pressure refrigerant vapor enters the compressor.
