The required refrigeration capacity of a vapour compression refrigeration system (with R-22 as refrigerant) is 100 kW at –30 C evaporator temperature. Initially the system was single-stage with a single compressor compressing the refrigerant vapour from evaporator to a condenser operating at 1500 kPa pressure. Later the system was modified to a two-stage system operating on the cycle shown below.At the intermediate pressure of 600 kPa there is intercooling but no removal of flash gas. Find:a) Power requirement of the original single-stage system;b) Total power requirement of the two compressors in the revised two-stage system.Assume that the state of refrigerant at the exit of evaporator, condenser and intercooler is saturated, and the compression processes are isentropic.

The required refrigeration capacity of a vapour compression refrigeration system (with R-22 as refrigerant) is 100 kW at –30 C evaporator temperature. Initially the system was single-stage with a single compressor compressing the refrigerant vapour from evaporator to a condenser operating at 1500 kPa pressure. Later the system was modified to a two-stage system operating on the cycle shown below.At the intermediate pressure of 600 kPa there is intercooling but no removal of flash gas. Find:
a) Power requirement of the original single-stage system;
b) Total power requirement of the two compressors in the revised two-stage system.Assume that the state of refrigerant at the exit of evaporator, condenser and intercooler is saturated, and the compression processes are isentropic.
