To provide a ventilation system which can increase the quantity of air supplied to a specific site while reducing costs.SOLUTION: A ventilation system 100 performs ventilation of an indoor space and includes: a ventilation device 10 (an air supply device) which takes air from an outdoor space into the ventilation system 100 and blows the air; multiple air supply ducts 20 which supply the air blown from the ventilation device 10 from multiple air outlets 30 (a first air outlet 31, a second air outlet 32, a third air outlet 33, and a fourth air outlet 34) to the indoor space; and a ventilation device 10 (an exhaust device) which exhausts air in the indoor space to the outdoor space. The multiple air supply ducts 20 include: normal ducts (a first duct 21, a second dust 22, and a third duct 23); and a different diameter duct (a fourth duct 24) having a passage whose cross sectional area is larger than those of the normal ducts.SELECTED DRAWING: Figure 2 【課題】コストの低減を図りつつ、特定の場所に供給される風量の増大を図ることができる換気システムを提供する。【解決手段】室内の換気を行う換気システム１００であって、屋外から空気を取り込み当該空気を送風する換気装置１０（給気装置）と、換気装置１０から送風された空気を複数の吹出口３０（第一吹出口３１、第二吹出口３２、第三吹出口３３、第四吹出口３４）から室内に供給する複数の給気ダクト２０と、室内の空気を屋外に排出する換気装置１０（排気装置）と、を具備し、複数の給気ダクト２０には、通常ダクト（第一ダクト２１、第二ダクト２２及び第三ダクト２３）と、流路の断面積が前記通常ダクトよりも大きい異径ダクト（第四ダクト２４）と、が含まれる。【選択図】図２
