本研究的主要目的是根据测量的中心线数据评估空气分配性能指数（ADPI），并确定湍流对ADPI的影响。数据是在一个带有高侧壁格栅的大型试验室（24×16×9英尺[7.3×4.9×2.7m]）中收集的。研究了在等温和非等温流动条件下，21个试验室中心线处的气流特性。结果表明，ADPI值是使用“中心线”数据和“整个试验室”确定的数据大致相同。ADPI结果强烈依赖于室内热负荷和空气流量。 采用舒适模型研究了湍流对ADPI的影响，并提出了一种改进的ADPI模型。结果表明，在高空气流量下，湍流强度强烈影响ADPI值。关键词:1996年，计算，湍流，气流分布，特性，气流，测量，计算，房间，热负荷，空气流量，空气运动，绘图:研讨会，ASHRAE Trans。1996年，第102卷，第2部分

The main objectives of this study were to evaluate the air distribution performance index (ADPI) based on measured centreline data and determine the effect of turbulence on ADPI. The data were collected in a large test room (24 by 16 by 9ft [7.3 by 4.9 by 2.7m ) with a high sidewall grille. The air flow characteristics at the centreline of the room for 21 test cases under both isothermal and nonisothermal flow conditions were investigated. The results showed that ADPI values determined using the "centreline" data and the "whole room" data were approximately the same. The ADPI results were strongly dependent on the room heat load and the air flow rate. The effect of turbulence on ADPI was investigated using a comfort model, and a modified ADPI model was presented. The results showed that the turbulence intensity strongly affected ADPI values at high air flow rates.KEYWORDS: year 1996, calculating, turbulent flow, air distribution, properties, air flow, measuring, calculating, rooms, heat load, air flow rate, air movement, draughts
