抄録

The car air conditioner evaporator is an aluminum heat exchanger that cools the air in an automobile. About 20 years ago, evaporators were treated only with chromate to prevent corrosion. Since the early 1980s, there has been increasing demand for hydrophilic properties for compact, highly efficient evaporators with narrow fin spacing and greater air flow to prevent increasing air pressure from dropping. In addition, the need has grown for greater demand for more comfortable air with fewer smells. A variety of odors emanate from air conditioners.<br>This report describes “rotten” odors, -mustiness, socks, etc.-caused by microorganism propagation, and methods to reduce odors by forming a hydrophilic treatment including a biocide. Culture and smell evaluation results suggest that the rotten odor caused by bacteria is stronger and more uncomfortable than that caused by fungi. We developed a way to prevent oder by surface treatment that provides the evaporator surface with hydrophilic properties and bacterial resistance.
