过滤和空气净化（FAC）是20世纪控制和清除受控环境中有害污染物的艺术和科学的关键和基本组成部分。它的开发和应用与建筑环境中通风和温度控制的发展同步。在这个过程中，它受到了许多社会、技术、工业和政治因素的影响。本演示将跟踪FAC行业的增长和成熟度的演变，以应对已确定的外部影响和需求。 这些影响因素包括医疗行业的发展和成熟；电子和计算机在工业过程控制中的作用；军队编制的需要；发展核能力；建筑环境中空调的扩散和广泛增长；应对室外空气中日益增加的污染物负担的挑战；大型和高层建筑的出现；人的发展- 制作建筑构件；对建成环境的生态和环境影响及排放的日益关注；对合理管理能源使用和成本的强烈关注；评估FAC性能的更精确和适用测试标准的作用和发展；以及使用机载大规模杀伤性武器的犯罪或恐怖袭击的普遍影响。引用:佛罗里达州奥兰多2020年冬季会议技术论文

Filtration and Air Cleaning (FAC) emerged during the20th century as a key and essential component of the art andscience of the control and removal of harmful contaminantsfrom controlled environments. Its development and applicationhas paralleled the advancement of ventilation and temperaturecontrol in built environments. In that process, it has been influencedby a number of societal, technological, industrial, andpolitical factors. This presentation will trace the evolution ofthe growth and maturity of the FAC industry as a response toidentified external influences and needs. These influencingfactors will include the development and maturing of thehealthcare industry; the role of electronics and computerizationin industrial process control; the needs of the militaryestablishment; the development of nuclear capability; theproliferation and wide spread growth of air conditioning in thebuilding environment; the challenge of dealing with increasedcontaminant burden in outdoor air; the emergence of large andhigh-rise building construction; the development of man-madeconstruction components; the developing concern for ecologicaland environmental impacts upon and emitting from thebuilt environment; the powerful concern for proper managementof energy usage and cost; the role and development ofmore precise and applicable test standards for evaluating FACperformance; and the pervasive influence of criminal orterrorist driven attacks employing airborne weapons of massdestruction.
