A building in a location is equipped with a heat pump system that is used for space heating in winter and cooling in summer. The seasonal COPs of the heat pump in winter and summer are estimated to be 2.2 and 2.8, respectively. The design heating load of the house is calculated to be 750,000 kJ/h for an indoor temperature of 25°C. The unit cost of electricity is $0.09/kWh. The annual heating degree-days in this location is 2400°C-days and the 97.5% winter design temperature is −9°C. The cooling degree-days are 1100°C-days. Determine the annual electricity consumption and its cost for heating and cooling of this house. Assume the same overall heat loss coefficient for winter and summer.

There are four thermostatically-controlled electric space heating loads of 1 p.u. power each. It is found that under certain weather conditions and for 1 p.u. voltage, they are on for four minutes and off for four minutes. The on-off cycle of the four heaters are initially symmetrically distributed so that two heaters are on at any point of time. The voltage suddenly drops to 0.894 p.u. Calculate the new on and off times for constant energy.
