To provide an air-conditioning and ventilation system that does not require maintenance such as cleaning of air-conditioning air ducts, since harmful substances such as dust, mold and malodor do not attach to, accumulate in, or condense within the air-conditioning air ducts, even if 24-hour operation is continued for a long period.SOLUTION: An air-conditioning unit 10 and air outlets 40, 41, 42 are connected by an air-conditioning air duct A 30 and an air-conditioning air duct B 31. Each of the air-conditioning air ducts is surrounded by at least any one of a room, a space and an insulating material between the air-conditioning air duct and the external skin of a building 2. Air-conditioning air at a difference of 5K or less during cooling and 10K or less during heating relative to the air around the air-conditioning air ducts is blown within the air-conditioning air ducts from the air-conditioning unit 10 towards the air outlets, thereby air-conditioning the room and space. Filter units A, B, C are provided inside the air-conditioning unit 10 and clean the air inside the building 2. An introduction fan and a filter 69 are provided in an external air introduction duct and clean external air being introduced. An exhaust fan is provided in an indoor air discharge duct to discharge, to the outside, some of the air that has passed through the air-conditioning air ducts and some of the air that has accumulated inside the building 2.SELECTED DRAWING: Figure 1 【課題】２４時間運転を長期間継続しても、空調送風路内に埃やカビや悪臭など有害物質が付着、堆積、結露しないので、空調送風路の清掃などのメンテナンスが不要な空調換気システムを提供する。【解決手段】空調ユニット１０と吹出口４０、４１、４２を空調送風路Ａ３０、空調送風路Ｂ３１で繋ぎ、空調送風路の周囲で、建物２の外皮との間に、それぞれ部屋、空間又は断熱材の少なくともいずれか一つを設け、空調ユニット１０から、吹出口に向けて、空調送風路の周囲の空気に対し、冷房時は５Ｋ以内、暖房時は１０Ｋ以内の空調空気を空調送風路内に送風して部屋及び空間を空調し、空調ユニット１０内にフィルタ部A、B、C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６９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送風路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
