R-134a is used in a vapor-compression heat pump cycle in which the refrigerant enters the adiabatic compressor at 2.4 bar, and 0 °C, with a volumetric flow rate of 0.8 m³/min, and leaves at 10 bar, 55°C. Liquid leaves the condenser at 34 °C. Determine:

A. The power input to the compressor (in kW)

B. Heating capacity of the system (in kW)

C. The coefficient of performance

D. The isentropic compressor efficiency.
