Controller
During the icemaking stage, the hot gas solenoid valve is closed. The hot refrigerant gas is
pumped out of the compressor to the condenser. The hot gas is cooled by fanforced air to cool the
liquid refrigerant after passing through the condenser. The drier and filter reduce possible dirt and
moisture in the refrigerant. The refrigerant expands in the evaporator cooling it so ice will form
while in the presence of water. Low pressure refrigerant gas returns to the compressor from the
evaporator where the cycle continues.
During the ice harvest stage, the solenoid valve is open. The hot refrigerant gas is pumped out of
the compressor to the evaporator through the hot gas valve. As the hot gas is not cooled by the
condenser, the refrigerant warms the evaporator. Ice in contact with the evaporator begins to melt
on the back side. The ice gradually ice slides off of the evaporator and drops to the storage bin.
