To promote defrosting from a surface of a heat exchanger to obtain excellent heat exchange efficiency for a long period, even when frost adheres to the surface of the heat exchanger, in a heat exchange system comprising a defrosting mechanism.SOLUTION: A heat exchange system comprises: a heat exchanger that is in contact with moisture-containing air and exchanges heat between a refrigerant flowing therein and the air to cool the air; a supply member holding an additive that reduces a contact angle of moisture adhering to the surface of the heat exchanger with respect to the surface of the heat exchanger; and a defrosting mechanism that defrosts frost generated by moisture adhering to the surface of the heat exchanger. During defrosting by the defrosting mechanism, the additive is supplied from the supply member to the surface of the heat exchanger.SELECTED DRAWING: Figure 1 【課題】除霜機構を備える熱交換システムにおいて、熱交換器の表面に霜が付着した場合でも、熱交換器の表面からの除霜を促進し、長期間にわたり優れた熱交換効率が得られるようにする。【解決手段】熱交換システムは、水分を含有する空気と接触し、内部を流通する冷媒と空気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水分の熱交換器の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、熱交換器の表面に付着した水分により生成する霜を除霜する除霜機構とを備える。除霜機構による除霜時において、供給部材から熱交換器の表面に添加剤が供給される。【選択図】図１
