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. WebbTo produce chilled water, the refrigerant absorbs heat from the water and thus, chilling the water to about 6.7°C (44°F). Afterward, the refrigerant rejects the heat to the condenser water, making the condenser water rise to about 35°C (95°F). Below is the refrigeration cycle that happens inside a water-cooled chiller:
