The chilled water from the ice maker's storage tank is continuously circulated through a plate or grid evaporator using a water pump; After the compressor runs, it undergoes suction compression exhaust condensation (liquefaction) throttling and then vaporizes at a low temperature of -10 to -18 degrees Celsius in the evaporator. Frozen water continuously condenses into an ice layer on the surface of the evaporator at a lower temperature of 0 degrees Celsius. When the ice layer condenses to a certain thickness, and the evaporation temperature of the refrigerant reaches the set temperature of the temperature control, the defrosting solenoid valve is connected, and the heat pump is often used to defrost, and then the next cycle is achieved.

An ice maker is a type of refrigeration mechanical equipment that cools water through an evaporator and generates ice through a refrigeration system refrigerant. It uses a refrigeration system and uses water as a carrier to produce ice through a certain device in an energized state. According to the principle of the evaporator and different production methods, the shape of the generated ice blocks also varies; People generally divide ice machines into particle ice machines, sheet ice machines, plate ice machines, tube ice machines, shell ice machines, and so on based on the shape of ice.
