Assume you live in apartment which is 3m high 15m wide and 20m long. The indoor temperature of 24C is maintained by a heat pump with COP of 3.1. The ventilation system of the house replaces the entire indoor air with fresh outdoor air at 5C and density of 1.25 kg/m, once per hour. Your roommate has gone for a month, and you prefer to maintain the indoor temperature at 18C instead of 24C. How much money can you save on a monthly bill if the electricity unit cost is $0.13 /kWh? Take Cp of air 1.005 kJ/kg C. Neglect the operating cost of duct fan. Round off your answer to the nearest integer. Hint: Total_mass-Mass_of_air_per_hour*24*30 Energy (Total_mass Cp Temperature_difference)/COP Cost-(Energy/3600) electricity_unit_cost .
