Abstract

In response to the requirements of building indoor purification in the post-COVID-19 era, six kinds of different filter units were selected (No.1—G4 carbon cloth, No.2—G4 polyester, No.3—F7 glass fiber, No.4—F7 electrostatic melt blown cloth, No.5—G4 polyester+F7 glass fiber, No.6-micro static charge electric module+G4 Polyester), and the PM_2.5 purification performance of different filter units were analysed through experiments. The primary filtration efficiency, PM_2.5 purification efficiency, resistance, CADR and CEE of the different filter units were tested. The results showed that: 1) No.5 and No.6 composed filter unit could effectively improve the primary filtration efficiency of the filter unit and PM_2.5 purification efficiency. 2) At the rated wind speed, the resistance of the No.2 filter unit was the lowest, and the resistance of the No.5 filter unit was the highest. 3) In the maximum air volume condition, CADR and CEE of the No.2 filter unit was the smallest, and CADR and CEE of the No.4 filter unit was the largest. The CADR and CEE of No.2 filter unit was about 7.13% and 6.54% of that of No.4 filter unit, respectively. Compared with No.2 filter unit, CADR and CEE of No.6 filter unit was increased by approximately 150% and 247%, respectively. The micro static charge electric module could promote the primary filtration efficiency and the PM_2.5 purification efficiency, and shorten the purification time effectively without increasing the resistance.
