| Abstract |
The air sterilization system investigated in the study presented in this paper allows occupants to turn on/off and to control the supply air speed and direction. The system can reduce bacteria, mold spores and viruses in the air by using UV sterilizer in the partition panels. The partition air sterilization system delivers conditioned and sterilized air to the personal task area through the partition panels that connect to the pressurized under-floor plenum. Room air exhausts through return grills mounted on the ceiling. The study established a full-size experimental environment to investigate the immunization performance of partition air sterilization systems. To find an optimal system that is able to achieve a sterilized healthy micro-environment, an experiment is considered to compare and analyze the performance of the partition air sterilization system in a typical office space. Multiple system parameters including volume flow rate and velocity of supply air were varied and investigated during the experiment. The more air was contacted with partition air sterilization system, the better we could eradicate air contamination. Over 90% of eradication ratio obtained by the partition air sterilization system indicates this system was efficient for removal of air contamination. |
