Very Low Temperature Refrigeration System

Main components of very low temperature refrigeration system

The very low temperature refrigeration system is mainly composed of compressor, condenser, filter, evaporator, expansion valve, control valve, electrical control system, etc.

Scope of application of very low temperature refrigeration system

The very low temperature refrigeration system is suitable for applications that require low-temperature cooling in processes such as pharmaceuticals, aerospace, petroleum, chemical industry, light industry, scientific research, gas liquefaction, etc. It is also used as low-temperature cold sources in various laboratories.

Very low temperature refrigeration system working principle

The working principle of the very low temperature refrigeration system is that after the high-pressure liquid refrigerant removes moisture through the dryer, it passes through the expansion valve to reduce the pressure and becomes low-pressure wet vapor, and then enters the evaporator to absorb heat and vaporize into low-pressure gas. The low-pressure gas enters The compressor forms a cycle.

Characteristics of very low temperature refrigeration system

1. Adopting independent refrigeration system design, the multi-head unit is relatively independent, with fewer moving parts and reliable operation;

2. Use high-efficiency economizer type semi-closed or open twin-screw compressors, which have high energy efficiency, reliable operation and long service life;

3. It can realize graded or stepless energy adjustment, flexible and convenient control, energy-saving, efficient and easy to maintain;

4. The compressor is equipped with an exhaust eliminator to ensure the low-noise operation of the unit;

5. An exhaust check valve is installed at the exhaust port to prevent the rotor from reversing during shutdown;

6. The flexible energy adjustment design enables continuous energy adjustment of the unit (stepless energy adjustment), ensuring the full performance of the compressor and helping users effectively save operating costs.
