3. From evaporator 8. Heat sensitizing tube
4. To compressor 9. Muffler
5. Pressure spring 10. Remote bulb
DUAL PRESSURE SWITCH
A control switch to stop further rotation of the compressor by turn-
ing OFF the electric circuits of the magnetic clutch and condenser
cooling fan when the cycling refrigerant is abnormally dropped or
risen in pressure.
EXPANSION VALVE
A device to eject the receiver/dryer-passed liquid refrigerant from
fine holes for sudden expansion to produce atomized refrigerant of
low temperature and low pressure.
EVAPORATOR
Passes therethrough the cold atomized refrigerant to lower the am-
bient temperature. The refrigerant, now changed into hot gas, is
sent to the compressor. Functionally, the evaporator acts just in-
versely to the condenser.
(The refrigerant takes a state of liquid when entering the evapora-
tor and a state of gas when leaving therefrom.)
