A heat pump operates on the ideal vapor-compression refrigeration cycle and uses refrigerant-134a as the working fluid. The condenser operates at 1400 kPa and the evaporator at 140 kPa. Determine this system's COP and the rate of heat supplied to the evaporator when the compressor consumes 7 kW. (Take the required values from saturated refrigerant-134a tables.) The COP of the system is and the rate of heat supplied to the evaporator is kW.
