History of Air Filtration and Air Cleaning: A100 Year Review of Significant Advances and Related Influences in the Advancement of the Art and Science of Filtration and Air Cleaning

摘要

Filtration and Air Cleaning (FAQ emerged during the 20th century as a key and essential component of the art and science of the control and removal of harmful contaminants from controlled environments. Its development and application has paralleled the advancement of ventilation and temperature control in built environments. In that process, it has been influenced by a number of societal, technological, industrial, and political factors. This presentation will trace the evolution of the growth and maturity of the FAC industry as a response to identified external influences and needs. These influencing factors will include the development and maturing of the healthcare industry; the role of electronics and computerization in industrial process control; the needs of the military establishment; the development of nuclear capability; the proliferation and wide spread growth of air conditioning in the building environment; the challenge of dealing with increased contaminant burden in outdoor air; the emergence of large and high-rise building construction; the development of man-made construction components; the developing concern for ecological and environmental impacts upon and emitting from the built environment; the powerful concern for proper management of energy usage and cost; the role and development of more precise and applicable test standards for evaluating FAC performance; and the pervasive influence of criminal or terrorist driven attacks employing airborne weapons of mass destruction.
