Modern air-conditioning system is composed of refrigeration system, heating system, ventilation and air purifying device and control system.
The automobile air conditioner generally mainly by the compressor (Compressor), electronic control clutch, condenser (Condenser), evaporator (Evaporator), Expansion valve (Expansionvalve), liquid storage dryer (Receiverdrier), pipe (Hoses), condensing fan, vacuum solenoid valve (Vacuumsolenoid), idling device and control system, etc. The automobile air conditioner is divided into high pressure line and low pressure pipeline. The high-pressure side includes the output side of the compressor, the high-pressure pipeline, the condenser, the liquid storage dryer and the liquid pipeline, the low pressure side includes the evaporator, the accumulator, the return trachea road, the compressor input side and the compressor oil pool.
Liquid storage Dryer--actually a device for storing refrigerant and absorbing moisture and impurities in refrigerant. On the one hand, it is equivalent to the car's fuel tank, for the leakage of refrigerant extra space to replenish the refrigerant. On the other hand, it filters out the impurities in the refrigerant, like an air filter. Liquid storage Dryer also contains a certain amount of silicone material, to absorb the role of water.
Condensers and Evaporators-they are different, but structurally similar. They are all covered in a row of curved pipe with a metal sheet of heat dissipation, in order to achieve the external air and the pipeline material heat exchange device. Condenser condensation refers to the cooling agent in its pipeline to heat from the gaseous condensed liquid. Its principle is similar to the engine radiator water tank (the difference is only in the tank is always liquid), so it is often installed in the front, and water tanks together to enjoy the breeze from the forward. In short, the condenser is where cool to go, so that its cooling condensation. The evaporator is exactly the opposite of the condenser, which is the place where the refrigerant absorbs heat from the liquid into a gaseous state (i.e. evaporation).
