Development Course And Composition Structure Of Deep Freezer Cold Room

Introduction of deep freezer cold room

The deep freezer cold room is always an important part of the logistics industry. The deep freezer cold room is mainly used for the constant temperature and humidity storage of semi-finished and finished products such as food, dairy products, meat, aquatic products, poultry, fruits and vegetables, drinks, flowers, green plants, tea, medicine, chemical raw materials, electronic instruments, tobacco, alcoholic beverages, etc. . The deep freezer cold room belongs to a kind of refrigerating equipment, which has much larger refrigerating area than the refrigerator, but they have the same refrigerating principle.

Equipment composition

The Refrigerating Chamber of a deep freezer cold room is usually cooled by a refrigerating machine, and the liquid (ammonia or freon) with very low gasification temperature is used as the coolant to make it evaporate under low pressure and mechanical control to absorb the heat in the storage, in order to cool it down.

Commonly used is the compression type refrigerator, mainly by the compressor, the condenser, the throttle valve and the evaporation pipe and so on constitutes. According to the evaporative tube device can be divided into direct cooling and indirect cooling. The evaporating tube is installed in the deep freezer cold room by direct cooling. When liquid coolant passes through the evaporating tube, it directly absorbs the heat in the cold storage room and reduces the temperature.

The indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower, and the air is heated by the evaporating pipe in the cooling device, and then sent into the warehouse to cool down. The advantages of air cooling are rapid cooling, uniform temperature in the reservoir, and the removal of harmful gases such as carbon dioxide during storage.
