COOLING/HEATING BUILDING USING COOL AIR STORAGE TANK, AND BUILDING COOLING/HEATING METHOD USING COOL AIR STORAGE TANK
To powerlessly circulate cool air and warm air in a building using a cool air storage tank in natural convection of the cool air and the warm air by gravity ventilation, and dispense with air-conditioning cost, facility cost and control cost by dispensing with installation of a blower fan and a blower duct using a humidity adjustment type natural exhaust port.SOLUTION: Ventilation passages 19 and 20 for communicating from an underfloor space 7 to an attic space 16 of a building 1 having an airtight structure are provided. A cool air storage tank 22 provided with a cooling device 23 is installed in the attic space 16, and a heating device 26 is installed in the underfloor space 7. A roof part 5 is provided with a humidity adjustment type natural exhaust port 25, and an air supply fan 24 for purifying outside air and supplying the purified air to the underfloor space 7 is installed in the building 1. The building stops operation of the heating device 26 during a summer season, flows down the cool air accumulated in the cool air storage tank 22 through the ventilation passage 20 and cools the inside of the building 1, and stops operation of the cooling device 23 during a winter season, operates the humidity adjustment type natural exhaust port 25 according to indoor humidity, and controls an amount of gravity convection.SELECTED DRAWING: Figure 1
【課題】重力換気による冷気・暖気の自然対流に冷気貯留槽を用いることにより、建屋内の冷気と暖気の環流を無動力で行い、湿度調整型自然排気口を用いることで送風ファンと送風ダクトの設置を不要にすることで、空調費、設備費及び管理費を不要にすることを目的とする。【解決手段】気密構造の建屋１の床下空間７から屋根裏空間１６を連通する通気路１９、２０が設けてある。屋根裏空間１６に冷却用機器２３を備えた冷気貯留槽２２を設置し、床下空間７に暖房用機器２６が設置してある。屋根部５に湿度調整型自然排気口２５が設けてあり、床下空間７に外気を浄化して供給する給気ファン２４が建屋１内に設置してある。夏季には暖房用機器２６の稼働を停止し、冷気貯留槽２２に蓄えた冷気を通気路２０を介して自然流下させて建屋１内を冷房し、冬季には冷却用機器２３の稼働を停止し、屋内の湿度に応じて湿度調整型自然排気口２５を作動させて重力換気の量を制御する。【選択図】図１
