Consider a residential heat pump that uses lake water as a heat source in the winter and a heat sink in the summer. The house is to be maintained at a winter temperature of 18oC and a summer temperature of 25oC. To do this efficiently, it is found that the indoor coil temperature should be 50oC in the winter, and 5oC in the summer. The outdoor coil temperature can be assumed to be 5oC during the winter months and 35oC during the summer. Compute for the COPs during (a) winter and (b) summer if it operates as a Carnot cycle heat pum

Consider a residential heat pump that uses lake water as a heat source in the winter and a heat sink in the summer. The house is to be maintained at a winter temperature of 18oC and a summer temperature of 25oC. To do this efficiently, it is found that the indoor coil temperature should be 50oC in the winter, and 5oC in the summer. The outdoor coil temperature can be assumed to be 5oC during the winter months and 35oC during the summer. Compute for the COPs during

(a) winter and

(b) summer if it operates as a Carnot cycle heat pump.
