をくりかえす。The system of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram for explaining the outline of this system. In the heating tower 1, the amount of heat of the outside air 2 moves to the antifreeze liquid 3 that drops from the upper part of the tower. The heating tower may be of any known open type or closed type, and a packed tower is preferable. The collected antifreeze liquid is collected in the heat storage tank 5, again raised by the pump 4 to the upper part of the tower, and sprinkled to repeat the heat collection.

る。The heat storage tank is a storage tank for antifreeze liquid, and the heat storage material 6 is contained in a container which is corrosion resistant to the antifreeze liquid and has good heat conduction.
The heat storage capacity can be increased by dipping
It is preferable to mix one or more heat storage materials having different melting temperatures.
Examples of these heat storage materials include a mixture of water and triethylene glycol (freezing point −24 ° C. to −3 ° C.).
【０００９】本発明のシステムにおいて、この加熱塔

を蒸発させ濃度を復元することができる。When the water in the outside air is taken up by the antifreeze liquid due to long-term operation of the heating tower and the concentration decreases and the freezing point rises, the outside air temperature is lower than the temperature of the antifreeze liquid, for example, by appropriately heating the heating tower at night. By operating, the water in the antifreeze can be evaporated to restore the concentration.

る。The relatively low temperature heat source in the heat storage tank, which is stored in the form of latent heat and sensible heat by the operation of the heating tower, is used as the heat source of the heat pump 7 during the time period when the electric power load is low, and the higher temperature heat source (for example, Warm water) 8 is obtained. The obtained high-temperature heat source has a high power load time zone, for example, during the daytime, by directly or indirectly utilizing it for heating, it is possible to reduce the power load in that time zone, and the heat pump has a low power load time zone. Combined with the use of electric power in, it can be used to eliminate the imbalance of electric power load depending on the time of day.

蓄熱槽に蓄えた。[Example] A heating tower with a cooling capacity of 20 horsepower and an antifreeze liquid (-10 ° C) was operated for about 10 hours in the daytime with an outside air temperature of 0 ° C to 5 ° C to collect heat with an antifreeze temperature of -5 ° C and a total calorie of 500 Mcal. I stored it in the tank.

数（ＣＯＰ）は２．４であった。Then, at night during low power load time, 50 m 3 of hot water having a temperature of 50 ° C. was obtained by using a heat pump with the antifreezing liquid in the heat storage tank as a heat source. The coefficient of performance (COP) of the heat pump was 2.4.

９Ｋｗｈ（７００÷０．８６÷２．４）である。With this hot water having a temperature difference of 10 ° C. and an efficiency of 0.85, the high power load time zone is from 8:00 to 18:00 (10 hours).
In addition, a part of the heating load average of 70 Mcal / h was used for heating. Assuming that the heating uses a heat pump with a coefficient of performance of 2.4, the electricity used for heating could be shared between day and night as follows. 1. Daytime (700-50 × 10 × 0.85) ÷ 0.86 ÷ 2.4≈133Kwh 2. Nighttime (equivalent to 50 m 3 × 10 ° C) 500 ÷ 0.86 ÷ 2.4 ≒ 242Kwh On the other hand, the electric energy during the daytime when the heat storage is not used is 33
