PROBLEM TO BE SOLVED: To solve the sick house syndrome, oxygen deficiency, and moisture damage by a ventilation system. SOLUTION: Air is fed from an attic of a thermally insulated and airtight building and exhausted from a toilet, a washroom, a kitchen, and a bathroom at all times. The airflow, or the ventilation can condition the moisture in rooms and wall cavities to improve the durability of the building, exhaust noxious gas in the rooms, and feed fresh air therein to make the rooms into healthy and comfortable spaces for persons. In summer, air is fed from the north or the east where the outside air temperature is low and hot air in the attic is exhausted to the south or the west side from exhaust ports. In winter, the air is fed from a high position in the attic in the south or the west side for using the living waste heat. This method can dispense with heat exchanging ventilation and provide the rooms with a lot of the circulating ventilation air volume and high amenity. |
