空气交换率是表征建筑能耗和室内空气质量的一个非常重要的参数。它的大小通常被报告为一个单一的数字，而没有注意空气交换率的不同值，即建筑物不同区域的通风效率。尽管这些差异也可能对总能耗产生一定影响，尤其是当整个建筑只有一个控制器时，但它们确实对室内空气质量评估产生了非常重要的影响。 这是因为，尽管建筑物内的平均空气交换量适当，但可能存在一个或多个空气交换率太小的区域，从而导致局部污染物。这些区域的浓度可能过高。本文介绍了一种多点示踪气体技术，用于量化不同住宅建筑不同区域的空气交换率。定义并计算了分区通风效率项，提出了室内空气质量评价结果的分析准则。 引文:研讨会，ASHRAE交易，1983年，第89卷，pt。华盛顿特区2B。

The air-exchange rate is a very important parameter in characterizing a building for energy consumption and indoor air quality. Its magnitude has often been reported as a single number, with no attention paid to different values of air-exchange rates, i.e., ventilation efficiencies in different zones of a building. Although these differences may also have some influence on total energy consumption, particularly when there is a single controller for the whole building, they do have very important consequences upon indoor air quality evaluation. This is due to the fact that, in spite of an appropriate average air exchange in the building, there may be a zone or zones where the air-exchange rate is too small, thus resulting in localized pollutant. concentrations in those zones, which may be excessive.This paper describes a multipoint tracer-gas technique that was used to quantify the air-exchange rate in different zones of various residential buildings. Zonal ventilation efficiency terms were defined and calculated, and a criterion for analysis of the results for indoor air quality evaluation is proposed.
