2. Overview of the various types of refrigeration compressors

2.1 Positive displacement compressors

The successive operations of sucking in steam at low pressure p _F , compressing this steam from p _F to p _C , and then discharging it into the condenser are achieved by variations in the volume of the compressor's internal capacities, connected first to the low-pressure space and then, after these volumes have been reduced, to the high-pressure space. Compression ratios, p _...
