WebThe refrigeration cycle is a thermodynamic cycle that is used to remove heat from a specific area you want to cool. The refrigeration cycle is also known as a heat pump cycle. This cycle is designed for refrigeration systems, air conditioning systems, and heat pumps. WebFeb 2, 2011 · The working fluid is the refrigerant, such as freon or ammonia, which goes through a thermodynamic cycle (see also Refrigeration ). The thermodynamic cycle is shown schematically in Figure 2 [Althouse et. al. (1982)]. Four important processes take place during the cycle.
