Through the supplementary water valve, the water automatically enters a water storage tank, and then the water is pumped through the flow control valve to the diverter head, where the water is evenly sprayed onto the surface of the ice maker and flows through the ice maker like a water curtain On the wall, the water is cooled to the freezing point, and the water that has not been frozen by evaporation will flow into the water storage tank through the porous tank and restart the circulation work.
When the ice reaches the required thickness (the thickness can be arbitrarily selected by the operator/user), the hot gas discharged from the compressor is reintroduced back into the wall of the ice maker to replace the low-temperature liquid refrigerant. In this way, a film of water is formed between the ice and the wall of the evaporation tube. This film of water will play a role of lubrication when the ice falls freely into the groove below by gravity. The water generated during the ice mining cycle will return to the water storage tank through the porous tank, which also prevents wet ice from being discharged by the machine.
1. The chilled water pump of the storage tank continuously circulates through the plate or grid evaporator;
2. After the compressor is in operation, it is vaporized by suction-compression-exhaust-condensation (liquefaction)-throttling-in the evaporator at a low temperature of -10 to -18 degrees. The frozen water continuously condenses into ice on the surface of the lower temperature evaporator at a water temperature of 0 degrees. When the ice layer is condensed to a certain thickness, the refrigerant evaporation temperature reaches the temperature-controlled set temperature, that is, the defrost solenoid valve is turned on and the heat pump is often used to de-ice, and then the next cycle is realized.
