To provide a duct-type air conditioning ventilation system in which dust, mold, bad smells, and other harmful substances do not adhere to or accumulate in an air conditioning duct and maintenance such as duct replacement and cleaning is not required even if 24-hour operation is continued for a long period of time.SOLUTION: Blowout ports are provided for rooms and heat insulation spaces in a highly airtight, highly heat-insulating building 2. An air conditioning unit 10 and the blowout ports are connected through air conditioning ducts, which pass through the heat insulation spaces. From the air conditioning unit 10 toward the blowout ports, air-conditioned air within 5 K during cooling and within 10 K during heating relative to the temperature of air around the air conditioning ducts is blown into the air conditioning ducts, so that the rooms and the heat insulation spaces are air-conditioned, and a filter part is provided in the air conditioning unit 10 to clean air inside the building 2. An outdoor air introduction path is provided with an introduction fan and a filter to clean outdoor air to be introduced. An indoor air discharge path is provided with an exhaust fan to discharge a portion of air that has passed through the air conditioning ducts and a portion of air staying in the building 2 to the outside.SELECTED DRAWING: Figure 1 【課題】２４時間運転を長期間継続しても、空調ダクト内に埃やカビや悪臭など有害物質が付着、堆積せず、ダクトの交換や清掃などのメンテナンスが不要なダクト式空調換気システムを提供することを目的としている。【解決手段】高気密高断熱な建物２内の部屋及び断熱空間に吹出口を設け、空調ユニット１０と吹出口を空調ダクトで繋ぎ、断熱空間に空調ダクトを通し、空調ユニット１０から、吹出口に向けて、空調ダクトの周囲の空気の温度に対し、冷房時は５Ｋ以内、暖房時は１０Ｋ以内の空調空気を空調ダクト内に送風することにより、部屋及び断熱空間を空調し、空調ユニット１０内に、フィルタ部を設けて、建物２内の空気を清浄し、室外空気導入路に導入ファンとフィルタを設けて、導入する室外空気を清浄し、室内空気排出路に排気ファンを設けて、空調ダクトを通過した空気の一部と建物２内に滞留する空気の一部を室外に排出する。【選択図】 図１
