WHOLE BUILDING AIR CONDITIONING SYSTEM

To provide a whole building air conditioning system having an air conditioning function and a ventilation function, and capable of being easily constructed and dispensing with maintenance of a duct.SOLUTION: A whole building air conditioning system 101 includes air conditioners 1a, 1b, a ventilation device 2, and a plurality of blow-out openings 5, 6 for blowing out the conditioned air supplied from the air conditioners 1a, 1b toward living rooms 3, 4 of a first floor and a second floor as air-conditioned object areas in a building 11. The air conditioners 1a, 1b are respectively disposed in attic spaces 7, 8 of the building 11, the attic space 7 is applied as an air supply passage for guiding the conditioned air supplied from the air conditioner 1b to the blow-out opening 5, and the attic space 8 is applied as an air supply passage for guiding the conditioned air supplied from the air conditioner 1b to the blow-out opening 6. Further a ventilation passage 9 for supplying the outside air sucked by the ventilation device 2 to the air conditioners 1a, 1b, and suction ports 10a, 10b for return air, and air return passages 20a, 20b are disposed to suck the air in the living rooms 3, 4.SELECTED DRAWING: Figure 1 【課題】空調機能と換気機能を兼備し、施工が容易で、ダクトのメンテナンスが不要な全館空調システムを提供する。【解決手段】全館空調システム１０１は、空調機１ａ，１ｂと、換気装置２と、空調機１ａ，１ｂから供給される調和空気を建物１１内の空調対象領域である一階並びに二階の居室３，４内に向かって吹き出す複数の吹出口５，６と、を備えている。空調機１ａ，１ｂはそれぞれ建物１１の内部の天井裏空間７，８に配置され、天井裏空間７を、空調機１ａから供給される調和空気を吹出口５に導く給気経路とし、天井裏空間８を、空調機１ｂから供給される調和空気を吹出口６に導く給気経路としている。また、換気装置２で吸い込んだ外気を空調機１ａ，１ｂに供給する通気経路９と、居室３，４内の空気を吸い込む還気用の吸込口１０ａ，１０ｂ及び還気経路２０ａ，２０ｂが設けられている。【選択図】図１
