Working Principle Of Ice Maker

Through the water replenishment valve, water automatically enters a water storage tank, and then through the flow control valve, the water is pumped to the diverter head, where the water is evenly sprayed on the surface of the ice maker and flows through the wall of the ice maker like a water curtain. The water is cooled to the freezing point, and the water that is not evaporated and frozen will flow into the water storage tank through the porous groove and restart the circulation.
When the ice reaches the required thickness (the thickness can be selected by the operator/user), the hot air discharged by the compressor is re-introduced into the ice maker wall to replace the low-temperature liquid refrigerant. In this way, a thin film of water is formed between the ice and the evaporation tube wall. This water film will play a lubricating role when the ice falls freely into the tank below by gravity. The water generated during the ice harvesting cycle will return to the water storage tank through the porous groove, which also prevents wet ice from being discharged by the machine.
1. The chilled water in the water storage tank is continuously circulated through the plate-type or grid evaporator by a water pump;
2. After the compressor is running, it goes through suction-compression-exhaust-condensation (liquefaction)-throttling-and then evaporates in the evaporator at a low temperature of -10 to -18 degrees to absorb heat. The chilled water condenses into an ice layer on the surface of the evaporator at a lower temperature at a water temperature of 0 degrees. When the ice layer condenses to a certain thickness, the evaporation temperature of the refrigerant reaches the set temperature of the temperature control, and the defrost solenoid valve is turned on to defrost, often using a heat pump, and then the next cycle is realized.
