Indoor Air Quality

, 2022
People spend a substantial fraction of their lives indoors (often 80-90%) and so these locations can represent a significant fraction of exposure to air pollution. Indoor air quality is a complex phenomenon but has been studied far less than air quality outdoors. In the absence of indoor sources of pollution, indoor air quality is determined by ingress

Numerical Analysis on Performance of Different Ceiling Coverage of fan Filter Units in Semiconductor Fabs [PDF]

E3S Web of Conferences, 2022
In practical semiconductor fabs engineering, in order to reduce the investment cost, low coverage rate of FFUs is usually adopted and the air supply velocity is high, which brings high resistance to the filter mounted at FFU’s outlet. If a higher ceiling

Indoor air quality guidelines [PDF]

Occupational and Environmental Medicine, 2002
“Health-based standards exist for outdoor air, and there are good arguments for developing equivalent indoor air quality guidelines” It seems self evident that if there are health based standards for outdoor air quality, there is no reason that there should not also be standards applied to the indoor environment. After all, it is indoors that we spend
