What is Refrigeration Cycle? The Refrigeration Cycle Explained

The refrigeration cycle is a cyclic process in which heat is transferred from a low-temperature object (or environment) to a high-temperature object (or environment) through a refrigerant, thereby cooling the object to a temperature lower than the environment and maintaining this low temperature.

Air compressor installation rules

1.Installation The selection of the installation site is most ignored by the staff. Often after the compressor is purchased, it is randomly located and used immediately after piping. There is no prior planning at all. Little did they know that such a sloppy result would cause future compressor failure and maintenance difficulties and poor compressed air quality.

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.
