The function of the condenser of the automobile air conditioner is to dissipate heat and cool down the high-temperature and high-pressure refrigerant vapor discharged from the compressor, so that it condenses into a liquid high-pressure refrigerant.
It can cool and liquefy the high-pressure, high-temperature refrigerant (gaseous refrigerant) sent from the compressor. The following is an introduction to the working principle of the car
air conditioner condenser:
1. When the refrigerant enters the evaporator, the pressure is reduced, from high-pressure gas to low-pressure gas. This process needs to absorb heat, so the surface temperature of the evaporator is very low, and then the cold air can be blown out through the fan. Condenser It is the high pressure, high temperature refrigerant from the compressor, which is cooled to high pressure and low temperature. Then go through capillary gasification and evaporate in the evaporator.
2. The
condenser and evaporator in automobile air conditioners are collectively referred to as heat exchangers. The performance of the heat exchanger directly affects the refrigeration performance of the automotive air conditioner. Its metal material consumption is large, its volume is large, and its mass accounts for 50% to 70% of the total mass of the entire automobile air conditioning device. The space it occupies directly affects the effective volume of the automobile, and it is difficult to arrange. Therefore, the use of high-efficiency heat exchangers is extremely important. The condenser and evaporator in the automobile air conditioner should be matched with the compressor, and should also be compatible with the throttling and expansion mechanism. The working state of the condenser and evaporator directly affects the capacity (refrigeration capacity) of the refrigeration system, the power consumption of the compressor and the economy of the entire air conditioning device.
