A heat pump needs to be designed to maintain a house at a constant temperature of 20 °C. Assume that the house loses heat at a rate of 10 kW to the cold exterior, while 5 kW of heat is generated internally (because of the presence of people, cooking, etc). The heat pump is to be run on an ideal refrigeration cycle with R134a as the working fluid. The heat is extracted by the evaporator from the ambient that is at 5°C. The selected values of properties around the cycle are listed in Table P.2 a) Fill out the enthalpy and entropy values in the table b) Draw the T-S diagram of the heat pump system c) Calculate the compressor work. d) Calculate the compressor efficiency. e) Determine the mass flowrate of the refrigerant f) Determine the COP of the refrigeration system.
