46 Evaporator (Ice Mold)
During the ice-making stage, the hot gas solenoid valve is closed. The hot refrigerant gas is
pumped out off compressor to condenser. The hot gas is cooled by fan forced air to warm liquid
refrigerant after passing through the condenser. The drier & filter reduces the possible dirty and
humidity in the refrigerant. The evaporator is cooled by the refrigerant. So ice can formed on the
evaporator during water is sprayed to the evaporator. Low pressure refrigerant gas may go back
compressor from the evaporator.
During the ice harvest stage, the solenoid valve is open. The hot refrigerant gas is pumped out off
compressor to evaporator through hot gas valve. As the hot gas is not cooled by the condenser, the
refrigerant makes the evaporator (ice mold) warm. So some ice touching the evaporator is thawed.
All of ice can slide down to the ice storage bin.
Water System
When the water supply pipe is connected with the main water supply, water will fill the water
trough through the floater valve till enough water inside water trough makes floater valve close.
During ice-making stage, water is pumped from the water trough to the water distribution tube. The
distributed water flow the surface of evaporator. Most parts of water go back water trough. Some
water is frozen on the evaporator step by step. The floater valve will open and fresh water is
recruited at any moment.
