Is the commercial freezer in Xue Cun fresh or frozen?

Refrigerator is another name for refrigerator and freezer. All evaporation tubes of high-quality refrigerators are made of high-quality copper coils and processed into wide-sided special shapes. Stainless steel plate has smooth surface and uniform thickness. The adoption of appropriate thickness not only ensures a long service life, but also makes the appearance of the freezer flat and firm. Copper pipe has better cooling transfer effect and corrosion resistance than aluminum pipe or composite pipe. High-quality copper coil has the advantages of high cleanliness and few pipe joints, which can effectively prevent leakage or blockage of refrigeration system. The circular tube is processed into a rectangle, which makes the contact between the evaporation tube and the cooling liner change from point contact to surface contact, thus expanding the transmission area and accelerating the cooling speed.
