| Abstract |
Today, we live in a world where serious environmental problems exist such as ultrafine dust. Ultrafine dust ha many health risks and can cause various diseases and allergies. Thus, the role of the ventilation system as an air cleaning technology is becoming crucial. In this study, the performance evaluations of the total heat exchanger using several types of HEPA grade filters were conducted for total heat exchange efficiency, valid total heat exchange efficiency, leakage rate, noise, energy coefficient, and particle capturing efficiency. The H13 grade filter shows the highest total heat exchange efficiency. Also, the H13 grade shows the greatest decrease in total heat exchange efficiency considering the leakage rate. The results of the particle cleaning capacity test shows that the H12 grade filter has the best particle cleaning efficiency. |
