An office building requires a heat transfer rate of 20 kW to maintain the inside temperature at 21 C when the outside temperature is 0 C. A vapor-compression heat pump with Refrigerant 134a as the working fluid is to be used to provide the necessary heating. The compressor operates adiabatically with an isentropic efficiency of 82%. Specify appropriate evaporator and condenser pressures of a cycle for this purpose assuming Delta_Tcond
