The freezer is actually a cabinet with refrigerating, island freezer and refreshing functions, while the refrigerated display cabinet has the function of a display freezer, and the door is transparent glass.
So how does the supermarket freezer cool and refrigerate food? First, the high-temperature and high-pressure gas generated by compressor compression is dissipated by the external fan through the fan, and becomes liquid at room temperature. The coolant after expansion by the high-temperature and high-pressure gas is used to heat the expansion valve and the pressure relief valve into the evaporator inside the machine. The internal circulation delivers air to the designated location, and the low pressure gas evaporates before returning to the compressor for compression, so it circulates.
Next is the refrigerated display case, the general freezer and freezer in the -2 ° C to + 8 ° C freezer to store fruits, vegetables, drinks, and - 16 ° C to 22 ° C - frozen meat, ice cream storage cabinets and so on. There is also a double warm freezer, freezer, with refrigeration and freezing functions. It can also be used in a variety of places, fruit cabinets, beverage cabinets, vegetable cabinets, meat cabinets, etc. can be used.
