研究中的样本包括1987-1988年供暖季测量的49栋住宅建筑和1988-1989年供暖季测量的242栋建筑。样本包括小型房屋和公寓楼，以及自然、机械排气和平衡通风系统。在49栋建筑中，使用衰变技术测量的空气交换效率在33%到53%之间变化。在49栋建筑中，使用恒定排放技术测量的污染物去除效率在8%到100%之间。主卧室的长期和短期局部空气交换指标采用衰变技术（49套住宅）和PFT技术（49套加106套住宅）进行测量。不同系统的平均值在80%到90%之间变化。 通风系统在去除污染物方面的性能通过平均周转时间来描述，平均周转时间是使用PFT技术在291个住宅中测量的。平均周转时间在0.5到15.3小时之间。在自然系统中，平均值为3.0小时，在机械排气系统中为2.5小时，在平衡系统中为2.5小时。单户住宅的平均周转时间（3.0小时）高于公寓楼（2.1小时）。关键词:通风，性能，家用，住房，供暖季节，公寓，自然通风，机械通风，平衡通风，换气率，效率，去污，卧室，测量引用:研讨会，ASHRAE Trans。1991年，第97卷，第2部分

The sample in the study consisted of 49 residential buildings measured during the heating season of 1987-1988 and 242 buildings measured during the heating season of 1988-1989. The sample included both small houses and blocks of flats, as well as natural, mechanical exhaust, and balanced ventilation systems. The air-exchange efficiency measured using the decay technique in the 49 buildings varied between 33% and 53%. The contaminant-removal effectiveness measured using the constant emission technique in the 49 buildings varied between 8% and 100%. The long- and short-term local air-exchange indicators in the master bedroom were measured using the decay technique (49 dwellings) and the PFT technique (49 plus 106 dwellings). The average values in various systems varied between 80% and 90%. The performance of the ventilation system in removing contaminants is described by the average turnover time, which was measured in the 291 dwellings using PFT technique. The average turnover times varied between 0.5 and 15.3 hours. The average values were 3.0 hours in the natural systems, 2.5 hours in the mechanical exhaust systems, and 2.5 hours in the balanced systems. The average turnover time in the single-family homes (3.0 hours) was higher than in the blocks of flats (2.1 hours).KEYWORDS: ventilation, performance, domestic, housing, heating season, flats, natural ventilation, mechanical ventilation, balanced ventilation, air change rate, efficiency, decontaminating, bedrooms, measuring
