Abstract
“Adherent odors” emitted from the evaporator in an air-conditioning (A/C) unit are caused by desorption of adherent odorant on the evaporator such as exhaust gas, cigarette odor, interior materials and so on. In an attempt to reduce adherent odors we have developed and initiated production of the ‘Adherent Odor Reductive Coating’.
In this paper we investigate the adherent and desorption mechanisms of these odors by componential analyses and odor sensory tests. As the result of the investigation, we find that the odor emission relates to hydrophilic group on the evaporator surface and we design evaporator coating based on the result. This paper also reports the positive effects that our ‘Adherent Odor Reductive Coating’ has in reducing adherent odors.
