Explanation: A schematic diagram of vapour compression refrigeration cycle is shown below Following are the process and changes in refrigerant when they pass through the different equipment of the refrigeration cycle Compressor-Process 1-2 : The refrigerant is compressed isentropically from stage 1 to stage 2. Condenser-Process 2-3: In the condenser, the heat is rejected by the refrigerant at constant pressure Expansion Device-Process 3-4 : The refrigerant is expanded in an irreversible adiabatic manner from stage 3 to stage 4. Evaporator-Process 4-1 : In the evaporator , heat is absorbed by the refrigerant at constant pressure.
