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 tube has better cold transfer effect and better corrosion resistance than aluminum tube or composite tube.

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.

1. The display cabinet should be placed on the flat ground, although the use environment is good. Don't lie on your back. The indoor environment where the refrigerator is decorated should be ventilated and dry. The top of the refrigerator is more than 50cm away from the ceiling, the left and right sides of the refrigerator are more than 20cm away from other objects, and the front of the refrigerator is more than 20cm away from other objects.

2. Newly purchased or transported display cabinets should be left standing for 2 to 6 hours before opening. Power on the cabinet for 2-6 hours before use, and do not start it immediately after shutdown. Wait for more than 5 minutes to avoid burning out the compressor. The thermostat gear of general freezer should be adjusted according to the season, ambient temperature and usage.

3. It is more appropriate to put the thermostat at 5 "or 6" in summer; In spring and autumn, it is more appropriate to set the thermostat at 3 "or 4". When using the freezer, the number of opening doors should be reduced as much as possible to shorten the time of taking food. Hot food should be cooled to room temperature before it can be put into the refrigerator. For indirect air-cooled refrigerators, when storing food, the food should not be too close to the air outlet.
