本文的目的是回顾气流分布系统和通风效果的科学文献，以确定和评估最适合各种空间的房间气流分布方法。在这项研究中，不同的通风系统进行分类，根据具体的要求和评估程序。这项研究表明，八种通风方法已在建筑环境中用于不同的目的和任务。调查表明，大量的研究已经进行了通风效果，但很少有研究已经做了关于气流组织的其他方面。在现有类型的通风系统中，由于房间中通风系统的不同用途和所使用的不同评估指标，每种通风方法的性能从一种情况到另一种情况而变化。本文认为，通风效果或效率的评价应根据通风系统的各项功能来确定，如散热、清除污染物、为呼吸区提供新鲜空气或保护乘员免受交叉感染等。分析结果形成了一个基本的框架，关于气流分布的应用，为设计师，建筑师，工程师，安装人员和建筑业主的利益。(C)2013爱思唯尔有限公司保留所有权利。
The objective of this article is to review the scientific literature on airflow distribution systems and ventilation effectiveness to identify and assess the most suitable room air distribution methods for various spaces. In this study, different ventilation systems are classified according to specific requirements and assessment procedures. This study shows that eight ventilation methods have been employed in the built environment for different purposes and tasks. The investigation shows that numerous studies have been carried out on ventilation effectiveness but few studies have been done regarding other aspects of air distribution. Amongst existing types of ventilation systems, the performance of each ventilation methods varies from one case to another due to different usages of the ventilation system in a room and the different assessment indices used. This review shows that the assessment of ventilation effectiveness or efficiency should be determined according to each task of the ventilation system, such as removal of heat, removal of pollutant, supply fresh air to the breathing zone or protecting the occupant from cross infection. The analysis results form a basic framework regarding the application of airflow distribution for the benefit of designers, architects, engineers, installers and building owners.
