建筑物通风系统的两个目的是（1）去除室内污染物和（2）提供热舒适。使用示踪气体技术和年龄分布理论测量通风效率，将特定位置的实际外部空气输送率与完美混合情况下的预测值进行比较ADPI是一个热舒适参数，它将干球温度和空速确定的有效通风温度与ASHRAE标准113（P）。在办公空间的标准条件下，在稳定的加热模式下，评估了三种不同的供应/回流配置，用于循环恒定体积系统。 在占用区域内的各个点上，通风效率在0.57到0.76之间，而ADPI测量值在50%到63%之间。在每个HC配置的测试中，供应空气到回风入口的短回路都是有效的。需要进行更多的研究，以确定现有系统在加热和冷却模式下的性能，并开发有效的填充通风策略。单位:双引文:研讨会，ASHRAE交易，1988年，第94卷，pt。德克萨斯州达拉斯1号

The two purposes of a building ventilation system are (1) to remove indoor contaminants and (2) to provide thermal comfort. Ventilation effectiveness is measured using tracer gas techniques and age distribution theory to compare the actual delivery rates of outside air at specific locations to those projected for the case of perfect mixing ADPI is a thermal comfort parameter that compares the effective draft temperature as determined by dry bulb temperatures and airspeeds to acceptability criteria established by ASHRAE Standard 113(P). three different supply/return  configurations were evaluated for a recirculating constant volumes ystemi n a steady heating modeu nder standard conditions for an office space. Ventilation effectiveness ranged from 0.57 to 0.76 at points in the occupied zone while ADPI measurements rangedf rom5 0%to 63%S. hort-circuiting of supplya ir to the return air inlet wase vident in tests of eachc onfiguration.
