PRESSURE HEAT EXCHANGE VENTILATION TYPE BUILDING
To provide a pressure heat exchange ventilation type building, which maintains positive pressure inside the building where radiant heat stays so as to prevent the intrusion of contaminated outside air, purifies the outside air with an outside air purification filter and a microporous adsorbent, controls heat exchange and ventilation based on temperature difference between the outside air temperature and indoor air temperature so as to maintain airtightness even in the summer for preventing intrusion of outside air, and suppresses the power consumption of heating and cooling.SOLUTION: An outside air purification chamber 12 is formed in the space under the floor of the airtight building 1, and a large number of microporous adsorbents and a heat exchange ventilation device 17 are arranged. An outside air suction pipe 18 having an outside air purification filter 19 and a discharge pipe 20 are connected to the heat exchange ventilation device 17. An air supply gallery 15 that connects the outdoor exhaust pipe 21 that opens to the room 11 to the heat exchange ventilation device 17 and communicates the outside air purification room 12 to the room 11 is provided on the floor. The heat exchange ventilation device 17 is set to outside air supply amount>outdoor exhaust amount so that the inside of the building 1 is constantly maintained at a positive pressure higher than the outside air pressure to suppress the intrusion of outside air.SELECTED DRAWING: Figure 1
【課題】輻射熱が滞留する建屋本体内を正圧に維持して汚染外気の侵入を阻止し、外気は外気浄化フィルターと微多孔吸着体により浄化し、外気温及び屋内外の温度差に応じて熱交換と換気を制御することで夏季にも気密性を維持して外気の侵入を防止し、また暖冷房の電力消費量を抑える加圧型熱交換換気式建屋を提供する。【解決手段】気密性を有する建屋本体１の床部下空間に外気浄化室１２を形成し、多数の微多孔吸着体と熱交換換気装置１７が配置してある。外気浄化フィルター１９を有する外気吸込み管１８と放出管２０が熱交換換気装置１７に接続してある。部屋１１に開口する屋外排気管２１を熱交換換気装置１７に接続し、外気浄化室１２を部屋１１に連通する給気ガラリ１５が床部に設けてある。熱交換換気装置１７は、外気給気量＞屋外排気量に設定して建屋本体１内は外気圧より高い正圧に常時維持して外気の侵入を抑制する。【選択図】図１
