Refrigeration Cycle Animation - Vapor Compression Cycle Explained

2a- Compressor (Vapor Compression Cycle): In this Refrigeration cycle system the refrigerant vapor from the evaporator is sucked in by a compressor which then compresses the vapor to a higher pressure. Hence the system is called a vapor compression cycle. The vapor is raised to a pressure such that its corresponding boiling (condensing) point ...
