Temp High Pressure Liquid Refrigerant from the condenser expands rapidly as the refrigerant is sprayed out through the fixed orifice in the capillary tube As a result the temperature and state of the refrigerant becomes low and mist like and therefore evaporates easily Evaporator The evaporator is a heat exchanger covered with slit fins Heat is removed from the air being pulled across the evaporator by the centrifugal fan The resulting cool air is expelled through the cooling air ducts Accumulator The accumulator is mounted on the suction gas pip ing between the evaporator and the compressor The accumulator separates the liquid refrigerant from the gas refrigerant allowing only the gas refrigerant to enter the compressor In the accumulator suction gas isled into a cylindrical vessel where the speed of the gas is decreased This process separates the refrigerant contained in From Evaporator j To Compressor lt the gas by the force of gravity causing the refrigerant to accumulate at the bottom of the vessel As a result the compressor is protected from possible damage caused by liquid refrigerant intake 12 page 700881 ELECTRICAL SYSTEM Circuit Diagram IDEALA Service Manual T S POWER CP i COM COMP co Comp COM Over Load H L FAN COM Motor TH1 OUT TEMP SEN1 SENSOR TH2 IN TEMP SEN2 SENSOR TH3 ICE TEMP SEN3 SENSOR PS PRESSURE COM
