WebFig.5-5: A 2-stage cascade refrigeration cycle. Cascade cycle is used where a very wide range of temperature between TL and TH is required. As shown in Fig. 5-5, the condenser for the low temperature refrigerator is used as the evaporator for the high temperature refrigerator. Cascading improves the COP of a refrigeration cycle. WebThe commonly used mechanical vapor compression cycle to produce refrigeration consists of four stages: evaporation, compression, condensation, and expansion (see Figure 2.4) (Green, 2008). The cycle that is used for single-stage vapor compression involves two pressures, high and low, to enable a continuous process to produce a cooling effect.
