Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 50C at a rate of 35 L/min and leaves at 750
Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 50C at a rate of 35 L/min and leaves at 750 kPa subcooled by 3C. The refrigerant enters the compressor at 200 kPa superheated by 3C. Neglecting changes in kinetic and potential energy and any stray heat transfer, please answer the following. a. Create a schematic of the cycle, use the same numbers used in your textbook for the inlet and exit states of each device, and include the energy exchanges between the cycle devices and the surroundings. b. Sketch the cycle processes on a T-s diagram. c. Determine the isentropic efficiency of the compressor d Compute the rate of heat supplied to the heated room. e. Determine the COP of the heat pump.
