[Prior art]

 As is well known, a typical building is one in which the inside and outside of the building are separated by walls, floors, ceilings, window glass, etc. By using the fittings we have, it is designed to maintain good ventilation of the building itself and to keep the inside of the building comfortable, and in the current house, it is a highly airtight building material such as an aluminum sash. The structure is designed to keep the inside of the building comfortable by making heavy use of.

By the way, the properties of a highly air-permeable building such as the Japanese house before the above and a highly air-tight building such as the present house are completely different. There is almost no temperature difference between the inside and outside of the building, and conversely, in a highly airtight building, the heat generated by electrical products such as TVs and refrigerators used inside the building is The temperature inside the building was 2-3 ° C higher than the temperature outside the building because it was sunk inside the building due to its height.

Further, looking at the above-mentioned current houses in more detail, since the building itself has high airtightness, the heat inside the building is difficult to escape, so that good warmth can be obtained in the winter season. However, in summer, the temperature inside the building is higher than the temperature outside the building, so the inside of the building feels very hot, and cold air outside the building is introduced, that is, ventilated or ventilated. Or it was necessary to use a fan or air conditioner.

[0005]

[Problems to be Solved by the Invention] According to the above conventional technique, the current house has a high airtightness of the building itself, and the heat inside the building is difficult to escape. Therefore, in order to overcome the heat in the summer, the ventilation is required. Alternatively, it is necessary to adequately ventilate or use a fan or air conditioner, but when performing the above ventilation or ventilation, it is done by opening the window glass etc. and operating the ventilation fan. However, when the window glass is left open, outside air does not enter the building unless there is some wind, and the ventilation fan is installed only in the kitchen or bathroom in most buildings, However, it was not possible to provide sufficient ventilation or ventilation in any case.

In the case of using the fan or the air conditioner, when the fan is used, the cool sensation cannot be obtained unless the wind of the fan is directly applied to the body, and the cool sensation is obtained after the sweat is dried. In addition, it is not desirable for health to keep the wind on the body for a long time, and when air conditioning is used, the airtightness of the building is high. Although the inside of the building is cooled well, the temperature difference from the outside of the building tends to be large and ventilation is likely to be insufficient, so it is not very healthy and it is difficult to maintain health in the summer. Moreover, the use of air conditioners tends to concentrate during the daytime in the summer, which causes social problems such that the power supply becomes insufficient.

[0007]
