When electrical appliances such as an air conditioner are used in a conventional wooden house, etc., the heating / cooling heat quantity obtained indoors easily escapes to the outside of the room. It was necessary to further increase the capacity of air conditioners, etc., and thereby increase the power generation capacity of solar cells.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a power facility inside a house by using night power, which has a low power cost, and power obtained from a solar cell in combination. It is an object of the present invention to provide a power supply system in a highly airtight heat-insulated house in which the cost of power equipment can be reduced and a comfortable living space can be obtained by being used.

[0008]

A power supply system for a highly airtight insulated house according to the present invention is a house in which the airtightness is enhanced by a floor panel, a wall panel and a roof panel in which a heat insulating material is densely filled. The openings such as windows that are constructed and formed on the walls are constructed with increased airtightness,

Moreover, after the temperature and humidity of each room 5 are sensed by the sensitive sensor 31 and the environmental information thereof is sent to the AI control device 32, the air conditioner 11 operates so as to obtain a comfortable room temperature and humidity.

In the hot water supply equipment 18, the heated hot water is stored in the heat storage tank T having a small heat radiation amount, and the hot water supply equipment of the kitchen 19 is supplied from the heat storage tank T through the piping equipment provided inside the house. Since it is designed to be supplied to 20 baths and baths, the hot water supply capacity in the house 1 can be sufficiently maintained by operating the heat pump system with low power consumption.

As can be easily understood from the above description, according to this embodiment, the floor panel 2, the wall panel 3 and the roof panel 4 which are densely filled with the heat insulating material are used.
Moreover, since the house 1 is constructed in a state where the airtightness is enhanced and the window opening method and the like are also enhanced in the airtightness, the heat quantity obtained in the room 5 is released to the outdoor 6. The structure is such that the heat loss that would otherwise occur is suppressed as much as possible, whereby the power consumption of the air conditioner 11 and the hot water supply device 18 operating in the house 1 can be significantly reduced.

Further, since the equipment scales such as the air conditioner 11 and the hot water supply device 18 are reduced, the cost can be reduced.

In addition, the air conditioner 11 and the water heater 1 are provided by the storage battery 24 charged by the solar cell plate 22 and the midnight power 23.
Since 8 operates, the efficiency of power consumption in the house 1 can be improved.

Further, since the solar battery plate 22 and the night electric power 23 can cover the daytime power consumption of the house,
When the amount of electric power supply reaches a peak in the electric power company, such as on a hot summer day, the house does not have to consume the electric power of the electric power company, and the peak value of the electric power supply can be lowered. Therefore, because it is difficult to store power,
