Compression Refrigeration Systems A two-stage compression refrigeration system with a flash chamber. Refrigeration Cycle In a vapor compression refrigeration system a gas (refrigerant) is alternatively compressed and expanded and goes from the liquid to the vapor state. Refrigerant (R22) vapour enters a positive displacement compressor at a slightly superheated state (1) and is then compressed to state 2. As an example, a three-stage refrigeration systems can provide a temperature of the evaporator out-100VC. It reduces leakage of refrigerant 4. Basic vapour compression refrigeration cycle consists of four major thermal processes; evaporation, compression, condensation and expansion .According to the requirement, vapour compression system is further modified for better performance and control.

Vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. 0000001763 00000 n 5.2 VAPOUR COMPRESSION SYSTEMS The challenge in refrigeration and air conditioning is to remove heat from a low temperature source and dump it at a higher temperature sink. When the fluid used throughout the cascade refrigeration system is the same, the heat exchanger between the stages can be replaced by a mixing chamber (called a flash chamber) since it has better heat transfer characteristics.
