Behavior of a heat utilization system using the diurnal range of atmospheric temperature in the summer is characterized by numerical simulation. The system consists of a radiator, a thermal energy storage tank, a fan-coil cooler, and an electric cooler. Conditions for the calculation are assumed from the actual weather and characteristics of appliances. Total consumption of electric power is used for evaluating the system performance. The larger the volume of the storage tank becomes, the smaller the consumption becomes, which relates with quantity of the liquid circulating between the tank and the radiator. The consumption is smaller in case the radiator is operated for a period of some limited hours than in case through the night. To decrease the consumption, there are also the most suitable values in the flow rate of the radiator pump and in the operating temperature of the fan-coil cooler. This system has a possibility to reduce demand for electricity or shift the demand to off-peak hours.
