室内气流组织是大空间室内热环境设计中的一个重要问题，它不同于普通建筑。如今，分层空调已成为大空间建筑的常见选择。分层空调的室内空气分布受许多设计参数的影响。这些参数直接影响热舒适性、环境噪声和能源消耗。因此，这些参数的选择成为大空间室内热环境设计的关键问题。本文以一座大空间建筑为研究对象。研究发现，冷却负荷随分层高度呈线性变化。计算了不同分层高度、直径和喷嘴数量条件下的气流分布。根据计算结果，绘制了对准图，以确定设计参数，如高度、直径和喷嘴数量，以及大型管道的选择范围- 太空大楼。根据图表分析了设计参数之间的关系及其优化选择。很明显，高度越低，能源消耗需求越少，但噪音水平会越高。在此基础上，提出了一种优化实用的大空间气流组织设计方法。单位:双引文:ASHRAE交易，第115卷，第。2、路易斯维尔2009

Indoor air distribution is a major concern in designing indoor thermal environment of a large space, which is different from normal buildings. Today, stratified air conditioning is acommon choice for large-space buildings. Indoor air distribution with the stratified air conditioning is affected by many design parameters. These parameters have direct effects on thermal comfort, environment noise and energy consumption. Selection of these parameters thus becomes the key problem indesign of indoor thermal environment in a large space. In this paper, a large-space building is taken as the study object. It was found that the cooling load varies linearly with the stratified height. The calculations of the air distributions were performed under the conditions of different stratified height, diameter and quantity of the blast nozzles. Based on calculatedresults, the alignment charts were plotted in an effort to determine the design parameters such as the height, the diameter and the number of blast nozzles and their selection range for a large-space building. According to the charts, the relationship of design parameters and their optimized selection are analyzed. It is clear that the lower the height, the less the energy consumption demand is, however, the noise level would be higher. Based on above results, an optimized and practical methodology is formulated for the design of the air distribution in a large space.Units: Dual
