The refrigeration principle of air-cooled refrigerators mainly relies on the air

The refrigeration principle of air-cooled refrigerators mainly relies on the air circulation of the refrigerator's refrigeration and freezing compartments. Generally, the refrigeration evaporator pipeline of this type of refrigerator is located in the freezing/refrigerating compartment, and the fan motor is also installed in the freezing/refrigerating compartment. At the upper part of the evaporator, when the compressor is working, the fan motor is powered on simultaneously, and the cold air is transmitted to the freezing and storage compartments through forced convection by the fan. Therefore, the refrigeration is relatively uniform, and the overall greenhouse temperature is very uniform. However, due to the forced convection effect of the fan, moisture evaporates quickly. (It is recommended to seal the ingredients with plastic wrap when placing them)

The evaporator used in air-cooled refrigerators is a finned evaporator, which is prone to frost formation on the fins. Therefore, a heater is generally installed on the evaporator. The structure of the heater varies depending on the design, installation method, and structure, but its main function is to melt the frost on the evaporator. The thickness of frost on the evaporator of a refrigerator can affect its cooling effect, so it is usually defrosted regularly. The defrosting cycle is achieved by switching between the heating system and the cooling system through a defrosting timer installed in the compressor room.

Snow brand commercial air-cooled equipment is equipped with a defrosting system, intelligent timed defrosting, relieving the trouble of manual defrosting, improving energy efficiency, increasing storage space, maintaining refrigeration effect, reducing maintenance work, and extending the service life of the refrigerator!
