Description

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

Refer to 

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.
