To provide an underfloor ventilation system capable of performing underfloor ventilation throughout the year with a simple configuration and improving indoor comfort regardless of the season.SOLUTION: An underfloor ventilation system is equipped with a winter ventilation device 20 installed in a floor part 14 of a building 10 and sending internal air of the building 10 to an underfloor 15, and a summer ventilation device 21 (ventilation device) installed in a foundation rising part 11 of the building 10 and sending external air of the building 10 to the underfloor 15. The summer ventilation device 21 and the winter ventilation device 20 vary a ventilation flow passage to the underfloor 15 between summer and winter. This allows indoor air or outdoor air to be introduced into the underfloor 15 according to the season, the underfloor 15 can be ventilated throughout the year with a simple configuration, and the comfort in the room can be improved.SELECTED DRAWING: Figure 1 【課題】簡単な構成で、通年における床下換気を行うことができ、季節にかかわらず、室内の快適性を向上させることのできる床下換気システムを提供する。【解決手段】建物１０の床部１４に配置され、建物１０の内部空気を床下１５に送る冬季用換気装置２０と、建物１０の基礎立上り部１１に配置され、建物１０の外部空気を床下１５に送る夏季用換気装置２１（換気装置）換気装置と、を備え、夏季用換気装置２１および冬季用換気装置２０は、夏季と冬季とで床下１５への換気流路を可変する。これにより、季節に合わせて、室内空気または室外空気を床下１５に導入することができ、簡単な構成で、通年における床下１５の換気を行うことができ、室内の快適性を向上させることができる。【選択図】図１
