Freezer cabinet, is a low-temperature refrigeration freezing equipment in order to achieve the effect of deep freezing. It is often referred to as a cooler, freezer, etc. Freezers have many uses, from the food industry to the medical industry and so on. According to the different use of the environment and the use of the effect requirements, the freezer cabinet refrigeration space from -45 ℃ to 0 ℃, each has its own zone.
Vaporization absorbs heat, liquefaction exothermic.
And air conditioning use the same principle, the freezer is the use of the compressor will be gaseous Freon compressed into a high temperature and high pressure gaseous Freon, and then sent to the condenser to dissipate the heat to become room temperature and high pressure liquid Freon, so the condenser blowing out is hot air. Then to the capillary tube, into the evaporator, due to Freon from the capillary tube to reach the evaporator after the sudden increase in space, the pressure decreases, the liquid Freon will be vaporized into a gaseous low-temperature Freon, which absorbs a large amount of heat, the evaporator will become cold, the use of refrigeration or air-cooled, to achieve the room (box) to cool down;
