A heat engine operates between thermal energy stores at 800 ° C and 20 ° C. Half of the power generated by the heat engine drives the Carnot heat pump, which is used to heat a house. While the interior temperature of the house is 22 ° C, the outside temperature is 2 ° C, the heat loss of the house is 62000 kJ / h. In these conditions, calculate the minimum heat that should be given to the heat machine per unit time as kW.
