A heat pump is used to heat a house. The heat loss of the house at a time when the outside temperature is A ° C is B kJ / h. The interior temperature of the house is C ° C. If the coefficient of action (COPIP) of the heat pump is D under these conditions , a) The power consumed by the heat pump [kW], b) The heat transferred from the cold outside air to the heat pump [kJ / h] c) If the heat pump is considered to work reversibly, calculate the COPIP

Question
A heat pump is used to heat a house. The heat loss of the house at a time when the outside temperature is A ° C is B kJ / h. The interior temperature of the house is C ° C. If the coefficient of action (COPIP) of the heat pump
is D under these conditions ,
a) The power consumed by the heat pump [kW],
b) The heat transferred from the cold outside air to the heat pump [kJ / h]
c) If the heat pump is considered to work reversibly,
calculate the COPIP.
