Table 3.1 Compressor types. The working principles of displace ment compressors and dynamic compressors differ significantly. In positive displacement compressors, a certain volume of gas is trapped in a space that is continuously reduced by the compressing device (piston, scroll, screw or similar) inside the compressor.
Traditional two stage refrigeration systems require two compressors, motors, and oil separators. They also require auxiliary equipment like an inter-cooler and all the interconnecting piping and valves required to connect to all the components. The MYCOM C-series Compressor Package only uses one increased space requirement.
Commercial refrigeration systems typically have three manual stem service valves.A suction service valve and a dis- charge service valve are located on the compressor.
