To obtain excellent heat exchange efficiency for a long time by preventing corrosion of a heat exchanger and also accelerating drainage from the heat exchanger with relatively little workload even if moisture adheres to the surface of the heat exchanger.SOLUTION: A heat exchange system includes: a heat exchanger for exchanging heat between air and a heating medium circulating inside to cool the air; and a supply member for holding an additive that reduces a contact angle of moisture in the air, adhering to a surface of the heat exchanger, relative to the surface. The additive includes a nonionic surfactant. The additive is supplied to the surface from the supply member. The concentration of the nonionic surfactant in a mixture liquid of the moisture adhering to the surface and the additive supplied to the surface has a value equal to or higher than that of a critical micelle concentration at 25°C.SELECTED DRAWING: Figure 1 【課題】熱交換システムにおいて、熱交換器の表面に水分が付着しても、比較的少ない作業負担で、熱交換器の腐食を防止すると共に熱交換器からの排水を促進することにより、優れた熱交換効率が長期間得られるようにする。【解決手段】熱交換システムは、空気と、内部を流通する熱媒体とを熱交換して空気を冷却する熱交換器と、熱交換器の表面に付着した空気中の水分の前記表面に対する接触角を減少させる添加剤を保持する供給部材とを備える。添加剤は、ノニオン系界面活性剤を含む。供給部材から前記表面に対し、添加剤が供給される。前記表面に付着した水分と、前記表面に供給された添加剤との混合液中のノニオン系界面活性剤の濃度が、２５℃における臨界ミセル濃度以上の値である。【選択図】図１
