Peration principle
Refers to two or more compressors in parallel to share a set of refrigeration circuit composed of refrigeration units.
According to the different cooling temperature and cooling capacity, the parallel unit can be in a variety of forms.
That is, the same set of units can be composed of the same type of compressor, or can be composed of different types of compressors. Can be composed of the same type of compressor, can also be composed of different types of compressor; It can be loaded with a single evaporation temperature or several different evaporation temperatures. It can be a single-level system or a two-level system. It can be either a single cycle system or a cascading system.
