| Outline of Final Research Achievements |
To improve the indoor air quality, we have developed an assist device of commercial air-purifier, which enhances its removal performance of allergenic airborne particulate matters such as pollen and house dusts. The prediction from computational fluid dynamic has shown that 30% increment of removal efficiency of pollen when the assist device with comparable flow rate with that of upward exhaust from the air-purifier is placed on a ceiling. We have manufactured the ceiling-mounted assist device which intakes the upward main flow stream from the air-purifier by the sirocco fan and has two-way exhaust.
