PURPOSE: To enhance the one simple pass elimination factor of odor and to obtain the deodorizing speed which has not heretofore been existed by coating the surface of the aluminum fin of a heat exchanger with ambient temperature oxidation catalyst by using binder. CONSTITUTION: A primer treated layer 11 is formed on the surface of the aluminum fin 9 of a heat exchanger 1, and coated with a deodorizing coat. The coat is coated with ambient temperature oxidation catalyst 10a and adsorbent 10b by using binder 10c. After fine powder such as dusts are collected from the air sucked from a suction port by a prefilter, odor components are adsorbed to the coat while passing the exchanger 1. At this time, if it is emitted by ultraviolet rays, titanium oxide of photocatalyst is excited, and hence the components are oxidation-decomposed at the ambient temperature to become odorless to be desorbed. Accordingly, the one simple pass elimination factor of the odor is enhanced to obtain the deodorizing speed which has not heretofore been existed. |
