Abstract

The purpose of this study is to serve as a method for reducing the particulate matter deposited on the indoor surface to maintain comfortable indoor air quality. To reduce the particulate matter deposited on the indoor surface, resuspension flow was generated. The optimal resuspension flow discharge direction and angle were confirmed experimentally for the effective interior surface deposited particulate matter reduction. To reduce the particulate matter deposited on the indoor surface, resuspension flow was generated in each direction to resuspend the deposited particulate matter and was then reduced using an air purifier. Resuspension flow was generated at 0˚, 90˚, 180˚, 270˚, and four-way based on the air front inlet. The experiment for each angle to reduce the deposited particulate matter measured the wind speed in the front inlet of the air purifier by generating the resuspension air flow at 30˚, 60˚, and 90˚ angles. Resulting from the experiment to remove indoor particulate matter using only the air purifier, the difference in the concentration of indoor particulate matter after the operation of the air purifier and when resuspended to confirm the removal of the deposited particulate matter was 47㎍/㎥. Meanwhile, resulting from the experiment that reduced indoor particulate matter by generating resuspended air flow for each direction, the difference in the indoor particulate matter concentration was 15㎍/㎥ at 0˚, 17㎍/㎥ at 90˚, 12㎍/㎥ at 180˚, and 19㎍/㎥ at 270˚. Resulting from the four-way experiments, the difference in the indoor particulate matter concentration was 6㎍/㎥. Therefore, the effect of reducing particulate matter deposited on the indoor surface by using four-way resuspension airflow was the best. As a result of measuring the average wind speed at the front inlet of the air purifier based on discharge angle, the wind speed was found to be 0.74m/s at 30˚, 0.75m/s at 60˚, and 0.77m/s at 90˚; thus, the wind speed was the fastest at 90˚.
