As more and more refrigerated cabinets are used, the chest freezer factory has made more and more modifications to the refrigerated cabinets for the convenience of people. However, no matter how the change is made, the control range of the freezer temperature has not changed, so when do we need to adjust the temperature, don't you know?
As we all know, the temperature distribution of refrigerators is uneven. The temperature in the refrigerator is a temperature step from top to bottom. The highest temperature is the lowest, about 3°C, while the lower fruit and vegetable box is the highest, about 6-10°C.
All evaporating tubes of high-quality refrigerators are made of high-quality copper coils and processed into wide-faced special shapes. The surface of the stainless steel plate is smooth and clean, and the thickness of the whole plate is uniform. Using an appropriate thickness can not only ensure a long service life, but also make the appearance of the refrigerator flat and strong. Copper tube has better cooling effect and better corrosion resistance than aluminum tube or composite tube. High-quality copper coils have the advantages of high pipeline cleanliness and fewer pipe joints, which can effectively prevent leakage or blockage of the refrigeration system. The round tube is processed into a rectangle so that the contact between the evaporation tube and the cold transfer sleeve changes from point contact to surface contact, which enlarges the transfer area and speeds up the cooling rate.
The storage principle of china freezer is the same as that of refrigerators. The temperature is absolutely different in summer and winter. When it is required to maintain the freshness of stored items, we need to adjust different temperatures in different seasons. It is the same temperature. We have four seasons a year, and the temperature in each season is different. Not everyone lives in an area like spring all year round.
