在过去20年里，空气污染越来越引起人们的关注。随着污染水平的上升，建筑居住者对“清洁”室内空气的需求也在上升。为了满足这些需求，空调系统的传统作用，即室内空气温度和湿度的控制，已逐步扩大。增加了空气清洗器、静电除尘器、高效过滤器和活性炭吸附器等部件，以去除室内空气中的颗粒物和异味。本研究的目的是确定空调设备在多大程度上可以去除供应给室内空间的空调空气中的污染物。该研究基于文献、设备制造商和研究人员提供的现有信息。 旅行者研究公司从1969年7月到12月进行了这项研究。结果在本报告中给出。

Air pollution has been a growing cause of concern over the past two decades. As pollution levels have risen, so have the demands of building occupants for "clean" interior air. In response to these demands, the traditional role of air conditioning systems, the control of interior air temperature and humidity, has progressively been expanded. Components such as air washers, electrostatic precipitators, high efficiency filters and activated carbon adsorbers have been added to remove particulate matter and odors from interior air.The objective of this study was to determine the extent to which air conditioning equipment could remove pollutants from conditioned air supplied to interior spaces. The study was based on existing information available from the literature, and from equipment manufacturers and research workers. The Travelers Research Corporation conducted this study from July through December of 1969. The results are presented in this report.
