Low temperature freezer

Low temperature freezer is relative to standard freezer, which generally has a temperature control range of 5 ℃ or above and below room temperature There are many production processes that require the provision of chilled water below 5 ℃, even minus 4 or 50 ℃, which requires low-temperature freezers, even ultra-low temperature freezers

According to the operating temperature, chillers with temperatures between 5 ℃ and 25 ℃ are called standard chillers, chillers with temperatures between 5 ℃ and minus 15 ℃ are called medium temperature chillers, chillers with temperatures between minus 15 ℃ and minus 35 ℃ are called low-temperature chillers, and chillers with temperatures below minus 35 ℃ are called ultra-low temperature chillers

working principle:

The working principle of a low-temperature freezer can be simply understood as the refrigerant passing through four processes in the refrigeration system: compression, condensation, throttling, and evaporation. This complete cycle continuously repeats itself, completing the refrigeration process of producing chilled water

During the operation of the chiller unit, the liquid refrigerant absorbs heat from the cooled object in the evaporator, vaporizes into low-temperature and low-pressure steam, is sucked in by the compressor, compressed into high-pressure and high-temperature steam, and discharged into the condenser. It releases heat to the cooling medium (water or air) in the condenser, condenses into high-pressure liquid, and is throttled by the throttle valve to become low-pressure and low-temperature refrigerant. It then enters the evaporator again to absorb heat and vaporize, achieving the purpose of circulating refrigeration

4. All electrical components are made of Schneider products from France;
5. Both the evaporator and condenser use internally threaded copper tubes, which increase the heat transfer area, have a smooth exterior, and enhance hydrophilicity

Low temperature freezer safety device

1. Compressor delayed start and overload protection;
2. Overload and alarm of water pump;
3. Phase and phase sequence protection;
4. High and low voltage protection;
5. High pressure safety valve for refrigerant;
6. Poor heat dissipation protection

The above protection systems are equipped with indicator lights and buzzer alarm devices

Low temperature chillers are also divided into two types: water-cooled chillers and air-cooled chillers. For units operating at temperatures above minus 25 ℃, air-cooled chillers or water-cooled chillers can be selected according to the factory environment. For units operating at temperatures below minus 25 ℃, water-cooled chillers are recommended to ensure sufficient cooling capacity
