A refrigeration unit is a set of chillers, referred to as a refrigeration unit. It is one of the most important components of compression refrigeration equipment. Based on structural and operational differences, similar to air compressors, refrigeration units can also be divided into several different types such as piston, screw, and centrifugal. A refrigeration unit uses a compressor to change the pressure of refrigerant gas to achieve low-temperature cooling. The compressors used in refrigeration units differ from general air compressors due to their specific operating conditions and compressed working media. A refrigeration unit is an efficient cooling device. Related thematic articles: Use of chilled water units.
