摘要
地板送风通常被认为是适用于置换通风的一种通风方式,然而当送风射流的初始动量足够大时,却能导致室内气流形成混合流动。所以定量地界定混合流与分层流产生的条件以及建立其性能分析方法对于地板送风系统的工程实践是十分必要的。
Floor air supply is usually thought as a means suitable for displacement ventilation,and yet it may result in mixing flow of room air as the initial momentum of the air supply jet is sufficiently great.Therefore it is essential to quantitatively define the occurring conditions of mixing flow and stratification flow and to find a performance analysis method for the engineering practice of floor air supply system.
