2. Description of the Related Art In a cooling system for a house, a building, etc., cold water or ice stored in a heat storage tank is used to store cold heat generated by using nighttime power in order to shift the power use time from the peak power demand to the peak off time. A heat storage system is used. These systems use nighttime electricity to generate cold heat, store this cold heat as ice in the heat storage tank, and extract the cold heat energy when it is necessary for cold heat in the daytime and use it for demand such as cooling. Moreover, the time lag between the generation of cold heat and the demand is made to correspond to the unbalance between the power demand day and night. As the ice heat storage tank, an ice heat storage tank that uses the heat of heat that has a small capacity of 1/80 of the sensible heat and has stable temperature characteristics is widely used.

[0003]

However, the use range of the ice heat storage tank is limited during the summer or cooling, and not only is it a useless space during non-cooling and winter, but the installation cost of the ice storage tank is high. Therefore, it has difficulty in cost performance, and it is hard to say that it is still popular enough. The present invention, in view of such technical problems,
The ice storage tank is not limited to summer or cooling, but can be effectively used even during non-cooling and in winter, thereby eliminating wasteful space and providing a multi-purpose building usage method that can improve cost performance. To aim.

[0004]

The present invention is applied to a building in which an ice heat storage tank is arranged at a predetermined position of the building. Buildings in this case refer to various structures such as buildings, domes, sports centers, gymnasiums, wedding halls, etc., and predetermined positions are the rooftops of basements, basements, dome, sports centers, gymnasiums, large commercial buildings, etc. Refers to the underground, indoors, or rooftop of the facility.
And a feature of the present invention is that the heat storage tank is formed in the recessed space, a floor is formed on the recessed space by using a removable partition wall and a removable floor, and the space below the floor is formed. It is characterized in that it serves as a ventilation passage for cooling the floor while making thermal contact with the cold energy stored in the heat storage tank.

In order to form the ventilation passage, for example, one or both of the upstream side wall and the downstream side wall of the recessed space formed by the partition wall and the downstream side wall are provided with a closable opening. It is preferable that a ventilation drive source is provided in either one of the openings. The partition wall is used to form a wind passage so that the wind flows over the entire lower side of the floor surface, but the partition wall is not limited to this and has a meaning of reinforcing the floor surface. In addition, a freezing refrigerant or brine pipe is laid in the heat storage tank, ice heat is stored by using nighttime electric power in the summer or cooling season, and a skating rink is formed using the pipe in the winter or non-cooling season. It is also possible to use it as a hot water pool by operating the heat pump using the pipe. The ventilation drive source is generally a blower connected to the opening of the upstream side wall, but is not limited to this. For example, the suction of a refrigerator installed in another building installed on the downstream side of the side wall. It may be on the side.

[0006]

According to the above technical means, the floor and the partition wall are removed in the winter season or the non-cooling season, and the skating rink is formed by using the refrigerant for freezing or the brine pipe laid in the heat storage tank, or on the pipe. It is also possible to lay a bottom plate for the pool on the outside, use the outside air heat source as an evaporator, and use the heat storage tank as a condenser for heat pump operation, and use it as a hot water pool. Then, in the summer or the cooling season, after installing the partition wall and the floor, ice heat is stored in the ice heat storage tank by using nighttime electric power, and the space below the floor is used as cold energy stored in the heat storage tank. It is possible to perform floor cooling while making heat contact. In this case, by the partition wall,
Uniform cooling of the floor is possible because the cooling air is formed to flow over the entire area below the floor. Further, since the floor surfaces are arranged at predetermined intervals, no matter how wide the floor surface is, the floor surface does not drop or wobble, and the floor surface can be sufficiently reinforced.

According to the invention, the heat storage tank formation area can be used as a commercial facility such as a skating rink and a hot water pool even in the non-cooling period when the ice heat storage tank is not used. It can be used and the cost performance with respect to the installation cost is greatly improved. In particular, both the heat storage tank and the pipes and chillers laid in the heat storage tank are used as commercial skating rinks and hot water pools, and the ice heat storage tank simply uses these installations during non-business periods. Therefore, the independent investment cost for ice heat storage becomes unnecessary, it contributes greatly to the reduction of running cost, and the profit base becomes very good. Therefore, the present invention provides a facility for installing a skate center or a hot water pool, a floor on the heat storage tank in the summer, a beer hall or a sports center with a strong seasonal color, mountaineering equipment or beachside clothing such as beaches or forest areas. It can be used for seasonal commercial facilities, as well as summer sports training camps, forest school facilities, etc., and can be used not only in resort areas but also in seasonal large commercial facilities in the suburbs and on the rooftops of buildings in central Tokyo. . In any case, the present invention is extremely preferable in developing a new business, because the ineffective space of the ice storage tank can be used for different purposes in different seasons in summer and winter. Further, the ice heat storage tank can be used for cooling of another building or another floor by utilizing the freezing refrigerant or brine piping, and as a result, double effect cooling can be performed.
