WebA 55 kW refrigeration load is to be carried by an air refrigeration system with a discharge pressure of 1370 kPa and a refrigerator pressure of 345 kPa. Compression and expansion processes are polytropic with n-1.37. The pressure at the start of the expansion is 1344 kPa and the temperature is 32°C. WebA refrigeration system is expected to have a high suction pressure when there is leakage of refrigerant through the discharge valve. Further, the compressor is not capable of providing the evaporator coil with the required refrigerant to handle the heat load.
