A two-stage compression refrigeration system with an adiabatic liquid-vapor separation unit like that in the figure uses refrigerant-134a as the working fluid. The system operates the evaporator at 100 psia the condenser at 300 psia, and the separator at 200 psia. The compressors use 29 kW of power. Determine the rate of cooling provided by the evaporator and the COP of this cycle. The refrigerant is a saturated liquid at the inlet of each expansion valve and a saturated vapor at the inlet of each compressor, and the compressors are isentropic. (Take the required values from saturated refrigerant-134a tables.) Compressor Compressor m6 m₂ Condenser Separator Evaporator The rate of cooling provided by the evaporator is ↓ Btu/h, and the COP of the refrigerator is
