An ideal multi-pressure refrigeration system consists of two Compressors serving one 60 Tons Evaporator at -20°C. The system uses two-stage compression with intercooling and flash Tank. A pressure reducer valve reduces the condenser pressure to intercooler pressure. The condensing temperature is 47•C. The refrigerant is R22. Calculate (a) enthalpy leaving evaporator (b) enthalpy leaving LP compressor (c) enthalpy entering HP compressor
