VEHICLE ATMOSPHERE PURIFYING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2013/014792

Kind Code:

A1

Abstract:

The purpose of the present invention, which relates to a vehicle atmosphere purifying apparatus, is to provide a direct ozone reduction (DOR) system such that a decrease in ozone purifying performance due to water attachment can be suppressed and ozone purifying performance can be recovered. According to the present invention, a core portion of each of radiators (14, 16) and a capacitor (18) is coated with activated charcoal as an ozone purifier. As shown in FIG. 5, when water becomes attached to activated charcoal pores or their surrounding areas, it becomes difficult for ozone to enter mesopores or micropores. Even if ozone could enter, it becomes difficult for electron donation to occur from the activated charcoal to ozone. Thus, the ozone purifying performance of the activated charcoal is decreased as long as there is the attached water. Thus, when the amount of water attached to the activated charcoal is not less than a predetermined amount, a water elimination control is performed to eliminate water by compulsorily heating the activated charcoal.
