In this case, not only is the energy wasted because it is locally heated, but there is also the danger that the heat shock associated with the movement between the rooms may impair health. In addition, there is a drawback that dew condensation occurs on the window glass, the ceiling, etc., which promotes the generation of mites and molds, which adversely affects the body, inner wall, outer wall, furniture, electric appliances and the like. Furthermore, the method of utilizing solar heat is limited to either hot water supply or heating, and the effective utilization of the collected solar heat was not sufficient.

[0004]

In order to eliminate such drawbacks, the present invention has at least an attic space, a living space, and an underfloor space, and a wall between the attic space and the underfloor space is an inner wall and an outer wall. For a house that is connected to the inner space, a heat insulating layer is formed between the roof, the outer wall, and the soil that surrounds the space, and either the space behind the hut, the space under the floor, the space over the roof, or the space inside the wall. At least one of the heat medium of the solar heat collector or exhaust, and a heat exchanger for exchanging heat with the sucked outside air are arranged, and the underfloor space is communicated with the outside through the heat exchanger, and A heat storage layer is laid on the heat insulation layer of the underfloor space, a pipe is embedded in the heat storage layer, the pipe is on the roof,
Contamination in the living space by forming a house in which a liquid or gas that serves as a heat medium circulates inside by connecting to a solar heat collector that is placed on either the outer wall or the outdoors and a heating auxiliary device that is installed indoors or outdoors The generated air and the air in the attic space are exhausted to the outside to improve the comfort of living, and in addition to prolonging the structure of the house and the articles in the house, it is possible to suppress the occurrence of mites and molds. Utilizing the solar heat collected by the solar heat collector extremely effectively,
By uniformly heating the entire house, we propose a house that is excellent in habitability, effective in saving energy, and environmentally friendly.
