What accessories do car air conditioners need to work
Automobile air conditioners need accessories composed of compressors, condensers, evaporators, expansion valves, receiver dryers, pipes, systems, etc. to work.
compressor:
The compressor is the "heart" of the air-conditioning refrigeration system, and it is a power source that makes the refrigerant circulating in the system. Its function is to inhale the low temperature
The compressed gaseous refrigerant is compressed into a high-temperature and high-pressure refrigerant, which is the transformation process of the refrigerant from a gaseous state to a liquid state.
Condenser:
The role of the condenser is to cool the high-temperature, high-pressure refrigerant vapor discharged from the compressor, condense it into a high-pressure refrigerant liquid, and then send it to
People reservoir dryer. There are three main types of condensers, namely tube-fin type, tube-band type, and fin type.
Reservoir dryer:
The liquid storage dryer can be seen literally, it has the function of storing liquid and drying. Its function is to provide extra space for leaking refrigerant
Replenish the refrigerant at the same time, and at the same time play the role of filtering, filtering out the impurities and moisture in the refrigerant.
Expansion valve:
Expansion valve, also called throttle valve, is the main component of automobile air-conditioning refrigeration system, and it is the boundary between high pressure and low pressure of automobile air-conditioning refrigeration system.
point. Its function is to throttle and reduce the pressure of the high-pressure liquid refrigerant from the receiver dryer, regulate and control the liquid refrigerant entering the evaporator
It can adapt to the change of refrigeration load, and at the same time can prevent the compressor from liquid hammer phenomenon (that is, the unevaporated liquid refrigerant is
Compression can easily cause damage to the compressor valve plate) and abnormal overheating of the evaporator outlet steam.
Evaporator:
The low-temperature and low-pressure liquid refrigerant is boiled and vaporized by absorbing the heat of the surrounding air through the evaporator, so that the surface of the evaporator and the temperature of the air are reduced,
Then it is cooled by the evaporator and turned into cold air sent to the car to cool down.
pipeline:
Since a certain pressure of refrigerant must be injected, metal pipes must be used. Especially from the compressor to the condenser to the refrigerant bottle to the expansion valve
Since this section is the high-pressure section of the system, it has higher high-pressure resistance requirements than other pipelines.
