An irreversible heat pump heats a home on a cold winter’s day. The home loses heat to the outdoors at a rate of Q̇ = B (Tin − Tout), where B is a constant equal to 0.5 [kW/K]. The coefficient of performance (COP) of irreversible heat pump is 50% of that for a reversible heat pump (i.e., β ′ = 0.5 β ′ rev ). If the indoor temperature is to be maintained at 20 °C and the power input to the heat pump is 5 kW: a) Determine the outdoor temperature, Tout. [5 marks] b) Determine the coefficient of performance of the heat pump, β′. [5 marks]

You are installing a heat pump whose COP is half the COP of a reversible heat pump. You plan to use the pump on chilly winter nights to increase the air temperature in your bedroom. Your bedroom's dimensions are 5.35 m ? 3.6 m ? 2.7 m. The air temperature should increase from 63° F to 68° F. The outside temperature is 35° F, and the temperature at the air handler in the room is 112° F. If the pump's...

Consider a residential heat pump that uses lake water as the heat source in the winter and as heat sink inthe summer. The house is to maintained at a winter temperature of T= 18 degrees C and a summer temperature of T= 25 degrees C. To do this efficiently, it is found that the indoor coil should be at T= 50 degrees C in the winter and T= 5 degrees C in the summer. The outdoor coil temperature can be...
