摘　　要：管道内风速风量是通风系统中非常重要的参数之一。日常工程项目中常常遇到需要对管道、风道等结构中的风量进行测量的问题;目前工程中常用的风道风量的测量方法有风速仪法测量,皮托管法测量,示踪气体法测量等;现实中需要根据工程实际结构和需求,比如管道结构、需求精度、可行性等来选取合适的方法测量;文中将对几种常用方法的优缺点进行比较探究,并重点对示踪气体法的计算方法进行分析,有助于工程上提高对测风量方法选取的可靠性。The wind speed in the pipeline is one of the most important parameters in the ventilation system.In daily engineering projects,it is often necessary to measure the air volume in pipelines,air ducts and other structures.At present,the commonly used measurement methods of duct air volume include anemometer,pitot tube,tracer gas,etc.In reality,it is necessary to choose the appropriate measurement method according to the actual structure and demand of the project,such as pipeline structure,demand accuracy,feasibility,etc.This paper will compare and explore the advantages and disadvantages of several commonly used methods,and focus on the analysis of tracer gas method,which is helpful to improve the reliability of the selection of air volume measurement methods in engineering.
