REFRIGERATION GASES
REFRIGERATION GASESRefrigerant gases are used in domestic refrigerators, air conditioners, industrial and commercial cooling machines for heat extraction from an enclosed space. In vapor compression refrigeration system, refrigerant enter the compressor as vapor and after adiabatic compression is heated to high temperature. The superheated vapor is cooled in a condenser which removes superheat and condenses the refrigerant to a liquid. The liquid refrigerant flows through as expansion valve where its pressure abruptly decreases through flash evaporation of approximately half the liquid. This results in a mixture of liquid and vapor at a low temperature and pressure. This cold liquid-vapor mixture then travels through the …
