由于通过通风供应入口进入受污染的室外空气而导致室内空气质量受损，可能会导致居住者的不适和健康状况不佳。最重要的是确保送风质量良好，并采取设计步骤确保受污染的室外空气不会无意中引入建筑物的通风系统。同样重要的是，确保排气口和其他污染源不位于现有供应入口附近。本研究的目的是解决建筑物通风入口的定位和尺寸确定问题。目标是:a）确定城市环境中的潜在污染源；b） 审查进排气口设计程序的最新信息；c）确定当前信息中需要进一步研究或量化的差距。主要调查人员: Brian A.摇滚，堪萨斯大学进行:1996年12月-1997年十一月赞助:TC 2.5，围绕建筑物的气流

Impaired indoor air quality arising from the entry of polluted outdoor air through ventilation supply inlets can be expected to contribute to the discomfort and ill health of occupants. It is paramount to ensure that supply air is of good quality and that design steps are taken to make sure that contaminated outdoor air is not inadvertently introduced into a building's ventilation system. It is also important to ensure that exhaust openings and other pollutant sources are not located in the vicinity of existing supply inlets. The objective of this research is to address the problems of locating and sizing building ventilation inlets. The goals are to: a) Identify potential pollutant sources in the urban environment; b) Review current information on inlet and exhaust outlet design procedures; and c) Identify gaps in current information that need further research or quantification.Principal Investigator: Brian A.
