A vapor-compression heat pump system uses R-134a as the working fluid. The refrigerant enters the compressor at 0.24 Mpa, 0 degrees Celsius, with a volumetric flow rate of 0.6m^3/min. The compression process is adiabatic to 0.9 MPa, 60 degrees Celsius, and saturated liquid exits the condenser at 0.9 MPa.
Find the following: a.) The power input to the compressor, in kW.
b.) The heating capacity of the system in kW (Qout)
c.) The coefficient of performance
d.) The compressor's isentropic efficiency.
