A heat pump is used for warming a house during winter and cooling it over summer. The temperature inside the house is set to 19o C during winter and 24o C during summer. The heat is transferred through the house walls and is estimated to be 2200 kJ/hro C. During winter, the outside temperature is 2o C. What is the maximal power required to operate the pump engine? Using the maximal power obtained for (a) to cool down the house during summer. If the house temperature should be maintained on 24o C, what will be the maximum temperature outside?

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
