HOT GAS VALVE
(also known as Automatic Discharge Relief valve)
The HX-100 uses a vertical-flow type hot gas valve, located
near the water tank wall. The HX-150 uses a base-mount type
hot gas valve, mounted near the center of the base of the unit.
OPERATION
This valve is closed during the cool cycle. When the unit
switches to heat cycle, the solenoid valve in the liquid line
closes, and the resulting decrease in suction pressure opens
the hot gas valve. This provides a path for refrigerant gas to
enter the evaporator directly without going through a liquid
phase, providing a heating effect.
