HFC-134a (R-134a) Service Tool and Equipment

• Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/

or its lubricant.

• Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/

lubricant.

• Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles

refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.

• Never use adapters that convert one size fitting to another: refrigerant/lubricant contamination occurs and

compressor malfunction may result.

Component

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-13, "Refrigerant Pressure Sensor"

.

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.
