(2) Refrigerant compressor (3) Stator vane (4) Rotor (5) Dust cover (6) Hub (7) Bearing (8) Magnetic clutch (9) Shaft (10) Coil (11) PulleyThe flow of refrigerant in the air conditioning system begins at the compressor.Compressor (2) receives driving force from the engine through magnetic clutch (8) via the V-belt.The compressor provides the following three functions in the refrigerant circuit: Suction, Pumping and Compression.Suction (Suction Side)
Suction lowers the refrigerant pressure in evaporator (13). Metered restriction is provided by expansion valve (28). Metered restriction allows high pressure liquid to be reduced to a vapor of low pressure. This helps with the evaporation of refrigerant, which leads to continuous cooling.Pumping
Pumping circulates the refrigerant in the air conditioning system. This also leads to continuous cooling.Compression (Discharge Side)
Compressing the refrigerant changes the refrigerant from a gas to a liquid. Condenser (4) assists in this process. When pressure increases, the temperature of saturation increases. Compressor (2) changes the refrigerant from a low pressure to a high pressure. This change must take place so that latent heat of condensation is given up when the refrigerant is sent through condenser (4) .
