The chest freezer is a low -temperature refrigerated freezing equipment that achieves deep freezing effects. It is usually called a cold cabinet, freezer, etc. There are many uses of freezing cabinets, which can be used in the food industry to the medical industry. According to different use environments and effect requirements, the refrigeration temperature of the frozen cabinet is from -45 ° C to 0 ° C, each with its own interval.
Frozen cabinets can be divided into home chest freezers and commercial cold cabinets. Household refrigerators generally refer to cold cabinets that use small capacity, more energy saving, and meet the needs of family life. Commercial cold cabinets are a relatively large capacity, focus on practicality, and can use industrial electricity cold cabinets.
The working principle of the frozen cabinet is the same as the use of the air conditioner. The cold cabinet uses the compressor to compress the fluid of the atmosphere into a high-temperature and high-pressure gaseous fluorine, and then sends it to the condenser to heat the heat. Hot wind. As Freon suddenly increases the space after reaching the evaporator from the capillary tube, and the pressure decreases, the fluid fluorine will vaporize and become a low -temperature fluorine, which absorbs a large amount of heat, and the evaporator will become cold. To cool down the room . It is worth noting that the part must be cleaned and disinfected regularly.
