1. (31- 31-30 points) A heat pump is to be used to heat a building during the winter. The building is to be maintained at 21°C at all times. The

building is estimated to be losing heat at a rate of135,135,000 kJ/h when the outside temperature drops to -5°C. Determine the minimum power required to drive the heat pump unit for this outside temperature? Complete the diagram.
