熱交換システム及びこれを備える応用機器

Abstract

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
