Problem- A Carnot heat pump is used to heat and maintain a residential building at 75 degrees F. An energy analysis of the house reveals that it loses heat at a rate of 2500 Btu/h per degrees F temperature difference between the indoors and the outdoors. For an outdoor temperature of 35 degrees F.
Part 1- Determine the coefficient of performance.
Part 2- Determine the required power input to the heat pump.
I need help to compute the coefficient of performance.
