Refrigerant 134a is the working fluid in a vapor compression heat pump that provides 35 kW to heat a dwelling on a day when the outside temperature is below freezing. Saturated vapor enters the compressor at 1.6 bar, and saturated liquid exits the condenser, which operates at 8 bar. Determine, for isentropic compression the: a) refrigerant mass flow rate, in kg/s. b) compressor power, in kW. c) coefficient of performance.
