Clean air delivery rate enhancement of air purifier by booster fans

According to the experimental test method provided by national standard, studies the principle of enhancing the air purifier’s clean air delivery rate （CADR）by the booster fan in a 30 cubic meter chamber. The results show that the booster fan enhances the CADR of the air purifier by increasing its own air volume. At the same time, the reliability analysis of experimental results shows that when approaching the test upper limit of CADR, a suitable diluter should be selected. Recommends no more than 5.5 times of the dilution ratio.
