What is the compressor power input in kw

Reference no: EM13546951

A vapor-compression refrigeration system, using Refrigerant 134a as the working fluid, has evaporator and condenser pressure of 1.4 bar and 12 bar, respectively. The refrigerant passes through each heat exchanger with a negligible pressure drop. At the inlet and exit of the compressor, the temperatures are -10 C and 80 C respectively. Thea heat transfer rate from the working fluid passing through the condenser is 15 kW. The saturated liquid exits the condenser at 12 bar. The compressor operates adiabatically. A) What is the mass flow rate of the refrigerant in kg/s? B) What is the compressor power input in kW?
