Evaporator
The mist form liquid refrigerant transforms to gas by evaporation by the air conveyed from blower
motor. The air is cooled by the heat by evaporation.
Condenser
Cools refrigerant discharged from compressor, and transforms it to liquid refrigerant.
Compressor
Intakes, compresses, and discharges refrigerant, to circulate refrigerant inside the refrigerant cycle.
Refrigerant pressure sensor
HAC-19, "Refrigerant Pressure Sensor"
(AUTOMATIC AIR CONDITIONING SYSTEM) or
HAC-150, "Refrigerant Pressure Sensor"
(MANUAL AIR CINDITIONING SYSTEM).
Liquid tank
Eliminates foreign matter in refrigerant, and stores temporarily liquid refrigerant.
Expansion valve
Transforms high-pressure liquid refrigerant to mist form low-pressure liquid refrigerant by drawing
function.
