报告了管道风道末端连接的泄漏数据。泄漏流量通常在总进近流量的1%到8%之间变化。发现在未密封条件下，泄漏量随着靠近终端的静压的增加而增加。对于刚性管道的边缘密封，发现泄漏小于未密封连接的一半。使用牵引杆将风道末端安装到柔性管道上，可以将轴环处的泄漏减少到几乎为零。建议在矩形供应或回流格栅上使用垫片，以减少泄漏。单位:SICitation:ASHRAE Transactions，第109卷，pt。1.

Leakage data for ducted air terminal connections are reported. The leakage flow rate generally varied from 1% to 8% of the total approach flow rate. Leakage was found to increase with the increase in the static pressure adjacent to the terminal for the unsealed condition. With marginal sealing of rigid ducts, leakage was found to be less than half that of the unsealed connection. The use of drawbands to mount air terminals to flexible ducts can reduce leakage at the collar to virtually zero. The application of a gasket to rectangular supply or return grilles is recommended as a means of reducing leakage.Units: SI
