Title:
AIR PURIFICATION DEVICE FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2012/131966
Kind Code:
A1
Abstract:
This invention pertains to an air purification device for vehicles, and the purpose of the invention is to provide a Direct Ozone Reduction (DOR) system that minimizes deterioration in the purifying function of an ozone-purifying body. There is a correlation between the ozone purification efficiency of activated carbon and the probability that gas is in contact with a radiator. There is also a correlation between the probability that gas is in contact with the radiator and the speed of the gas passing through the radiator. There is also a correlation between the speed of the gas passing through the radiator and vehicle speed. Therefore, there is a correlation between the ozone purification efficiency of activated carbon and the vehicle speed. Thus, a grill shutter (22) is fully opened when the vehicle speed is faster than the speed (A) indicated in figure 6. Meanwhile, the grill shutter (22) is fully closed, as per figure 2 (A), when the vehicle speed is slower than the speed (A).
