An air-conditioning unit 10 and air outlets 40, 41, 42 are connected by air-conditioning air duct A 30 and 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 the building 2. Air-conditioning air at a difference of no more than 5K during cooling and no more than 10K 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 spaces. 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. As a result of the above, the present invention provides an air-conditioning and ventilation system that does not require maintenance such as cleaning of the air-conditioning air ducts, since harmful substances such as dust, mold and odors do not attach to, accumulate in, or condense within the air-conditioning air ducts, even if 24-hour operation is continued for long periods.

[Problem] The purpose of the present invention is to provide a duct-type air conditioning ventilation system in which dust, mold, odors, 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] Air drawn in from a suction part 44 through a circulation path is cleaned by a filter part A. A portion of the air drawn in is air-conditioned and cleaned by an air conditioning unit 16 and a filter part B. Blown air blown out from the air conditioning unit 16 and the remainder from the portion of the air drawn in are mixed in a mixing unit 85 by a plurality of blower units 13. Air-conditioned air within 5 K during cooling and 10 K during heating relative to the temperature of air around air conditioning ducts 30-34 is blown into the air conditioning ducts 30-34 toward blowout ports while being further cleaned by the plurality of blower units 13 and a filter part C, whereby rooms 20, 21 and a heat insulation space are air-conditioned and air-cleaned. 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 in the circulation path and/or a portion of air staying in a building 2 to the outside.
