| Abstract |
Recently, the use of UVGI system has been increasing in both medical and nonmedical buildings for the control of environmental microorganisms. In the present study, irradiance performance test of UVC lamp was carried out and indoor air sterilization effect of UV ray for preventing transimission of air borne contagion was investigated by using manufactured UVC air sterilizer. Experimental results show that the effective irradiance of UVC lamp is strongly dependent on air velocity and temperature in irradiance performance test. An individual microbiological killing effectiveness experiment also shows that the average kill rate of two microbiological samples such as bacteria and fungus is about 92% by using manufactured UVC air sterilizer. Additionally irradiance performance experimental results also show that the ballast is very important factor to keep up irradiance performance of UVC lamp. |
