The main component system of automobile air conditioning.

   Modern air conditioning system consists of refrigeration system, heating system, ventilation and air purification unit and control system.

   Automobile air conditioning general mainly by the compressor (compressor), electric clutch, (condenser, evaporator, condenser, evaporator), expansion valve (expansionvalve), liquid dryer (receiverdrier), pipe (hoses), the cooling fan, vacuum electromagnetic valve (vacuumsolenoid), idle speed device and control system, etc. The automobile air conditioning is divided into high pressure pipeline 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 evaporator, accumulator, return air line, compressor input side and compressor oil pool.

   Liquid storage dryer - is actually a storage refrigerant and absorption refrigerant water, impurities device. On the one hand, it is equivalent to the fuel tank of the car, which provides a space supplement refrigerant for the leakage of refrigerant. On the other hand, it filters out impurities in refrigerants like air filters. There is a certain silica gel in the storage dryer, which can absorb water.

  The condenser and the evaporator -- they're called different, but they're similar in structure. They are all in a row of curved pipes full of heat-dissipating metal wafers to achieve heat exchange between the air and the material in the pipeline. Condensers refer to the refrigerants in their pipes that heat from the gaseous state to the liquid state. Its principle and the heat dissipation of the engine water tank close (difference is in the water tank of water has always been a liquid), so it is often installed in the front, with water tank, enjoy blowing cool wind from the frontier. In short, the condenser is where it is cooled so that it cools and condenses. The evaporator is the opposite of the condenser, which is the place where refrigerants absorb heat from the liquid into the gaseous (i.e., evaporation).
