Webbvapour is compressed. The refrigerant rejects heat to the atmosphere by condensing into a liquid inside a heat exchanger, the condenser. The refrigerant then goes through an expansion device (usually a valve) and is returned to the evaporator to start the cycle again. Many systems employ more sophisticated cycles, but the basic principles apply. Webb24 sep. 2024 · In early years of refrigeration system ( early 20th century ), vapor absorption cycle using water ( absorbent ) ammonia ( refrigerant ) system was widely used. Later due to low coefficient of performance ( i.e about 1/5 th of vapor compression cycle ) it was later replaced by the more efficient vapor compression cycle.
