摘　　要：文章对空气分布器性能试验的主要现行标准JG/T 20、EN 12238、EN 12239和ASHRAE 70进行了内容梳理,首先从空气分布器有关参数、测量仪表要求和风口试验过程要求方面对比了3类标准的异同。在此基础上,重点分析了ASHRAE 70和EN 12239中置换型风口的试验方法及应用特点。具体为从压力损失试验、射流特性试验、噪声性能试验等方面归纳和对比了常规风口的通用试验方法。对于置换型风口,则依次介绍了水平送风、地板送风和诱导送风的风口试验特点。旨在为通风空调风口的试验及研究提供借鉴,为未来风口试验标准的完善提供参考。This study systematically reviews the current main standards JG/T 20(ISO 5219),EN 12238,EN 12239,and ASHRAE 70 for performance testing of air distributors.It first compares the differences and similarities across these standards in terms of air dis tributor parameters,requirements for measuring instruments,and requirements for testing procedures.Subsequently,it focuses on analyzing the test methods and application characteristics of displacement flow distributors in ASHRAE 70 and EN 12239.Specifical ly,it summarizes and compares the general test methods for conventional air distributors,including tests for pressure loss,jet characteristics,and noise performance.For displace ment flow distributors,it sequentially introduces the test characteristics of horizontal air supply,floor air supply,and induced air supply.The aim of this study is to provide in sights for the testing and research of air distributors and to offer references for the further improvement of testing standards.
