摘要
目的研究改进和评价室内空气质量的实用方法。方法在大量的现场调查研究的基础上,根据室外风速、风向频率和室内外温差估算室内综合换气次数。结果实测值与计算值最小偏差为2%,最大偏差为46%,平均偏差17.1%。结论室内综合换气次数可以科学地反映室内空气质量。
Objective To find a practical and simple method for the indoor air quality assessment. Methods Based on the data of air exchange frequency measurement, estimated the synthetic air exchange frequency according to the differences between indoor and outdoor temperature and the outdoor meteorological data. Results In the present study the minimal error was 2%, the maximal error was less than 46 % and average error was 17.1 %. Conclusion Synthetic air exchange frequency may objectively reflect the indoor air quality.
