美術館空気質の実態調査と測定法の検討 : 美術館の空気質ガイドラインに関する基礎研究 その1

抄録

An international standard of acceptable indoor air quality in museums has never been established. The purpose of this study is to identify suitable methods for monitoring air quality in museums. In order to grasp the present situation in museums in Japan field investigations in a museum in Tokyo were conducted in both HVAC operation and non-operation time. The results found that the concentrations of ammonia, formaldehyde and TVOC in HVAC non-operation time were higher than those in operation time. For these pollutants the elapsed time effects on reducing concentrations could be seen. Regarding nitrogen dioxide, the concentration of indoor air was lower than that of outside, and consequently the concentration in HVAC operation time was higher. For some of these pollutants passive methods were proposed and their applicability was examined .
