  • Publication number: 20200064086
    Abstract: A heat exchanger having a polyamine on at least part of a surface of the heat exchanger. The existence of polyamine on the surface of the heat exchanger allows the odor components to be temporality held by virtue of the action of polyamine, and the odor components are not released into an interior room or the like at once in conjunction with the evaporation of free water (such as condensed water). Thus, the release of odor components is made moderate, and changes in the concentration of odor components in the interior room are reduced, so that strong odors sensed by people are suppressed. A typical example of the polyamine is PEI, and a typical example of the heat exchanger is an evaporator used in a car air-conditioner.
