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.

The heart of the compressor's refrigeration system

The heart of the compressor's refrigeration system If a person does not have a heart, it is equivalent to a dead person! The "heart" of a car is the engine. If there is no engine, the car is equivalent to scrap iron. The "heart" of the refrigeration system is the compressor. Now that summer is here, all kinds of air-conditioning, cold storage, chemical refrigeration processes, etc.

Quick look Small chillers summer maintenance tips

Quick look! Small chillers summer maintenance tips The high-temperature summer is a frequent season of safety production accidents, which affects the cooling effect of small chillers to a certain extent. Therefore, in order to reduce the equipment failure time and the losses it brings, we must always pay attention to the impact of high temperature on the small chiller equipment, and do a good job in the summer maintenance of the small chiller.
