Problem 3 A home in a Midwestern city is being heated with a heat pump in a winter day where the outside temperature is 5 C. Due to poor insulation, the home loses 800 KW of heat to the outside surroundings. An space heater inside the room generates 150 KW and another 120 KW of heat is generated by all the appliances and people in the room. The home is desired to be maintained at 25°C The heat pump consumes...
