Compressor operation in the heart of the refrigeration system in 2020

Compressor operation in the heart of the refrigeration system in 2020 A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby achieving compression-condensation (heat release) )-Expansion-evaporation (heat absorption) refrigeration cycle.

Detailed product knowledge about Danfoss expansion valves

The thermal expansion valve is used to adjust the supply amount of liquid refrigerant in the evaporator. The supply amount is controlled by the superheat of the refrigerant. Therefore, this valve is particularly suitable for the supply of refrigerant liquid in the dry evaporator. Because the refrigerant superheat at the outlet of the dry evaporator is proportional to the load of the evaporator.
