Single-stage cycle of a pure refrigerant or an azeotrope
Refrigerating machines theory - Mechanical compression machines. Single-stage cycles

The basic single-stage compression cycle and the ideal temperature profile of the refrigerant and the cold and hot heat transfer fluids in the exchangers of this system are shown in figure 1 .

The simple, highly symmetrical single-stage compression machine comprises the following components.

The evaporator vaporizes the refrigerant, removing heat from the coolant, which cools from q _f1 to q _f2 . The vapor leaving the evaporator is saturated. Evaporation takes place at the vaporization temperature q _F...
