What is the working principle of a two stage compressor?
Condense it to the condensing pressure PK and drain into the condenser. In this way, the levels of pressure ratio is moderate, because after intermediate cooling, and can make the compressor power consumption is reduced, the reliability and economy are improved
The low-pressure refrigerant vapor from the evaporator (pressure P0) is advanced into the low-pressure compressor, which is compressed to the intermediate pressure PM, and then cooled into the high pressure compressor,
In the two stage compression refrigeration cycle, the refrigerant compression process is carried out in two stages
