The direct cooling block ice machine adopts direct evaporation refrigeration technology, which circulates the refrigerant in the evaporator and directly absorbs the heat of water to achieve rapid freezing. The process can be divided into:
Refrigerant compression: The compressor compresses the gas refrigerant into a high temperature and high pressure state
Condensation heat release: High pressure refrigerant releases heat in the condenser and converts it into liquid state
Evaporation heat absorption: Liquid refrigerant enters the evaporator and directly contacts the mold, causing a sudden drop in water temperature and forming high-density ice blocks
Demoulding storage: After the ice cubes are formed, they are automatically demolded and enter the low-temperature storage compartment
Compared with traditional saltwater ice making, its refrigeration efficiency is increased by more than 30% and energy consumption is reduced by 40%
