研究静压送风道的阻力分布规律，对提高送风均匀性和改善送风道性能有重要意义。
Hence, for improving the uniformityof air supply and the performance of the duct, it is of great importance to studythe rules of resistance distribution in static pressure air supply duct.
通风机房洞室群一般包括：排风通道、送风通道、运输通道、人行通道、设备房、联络送风道、联络排风道等。
Ventilation cabinet includes exhaust air tunnel, supply air tunnel, transport tunnel, pedestrian tunnel, equipment cavern, cross-passage etc.
对不同类型的空调静压送风系统进行了送风均匀性测试，测试结果表明，传统的空调静压送风道送风均匀性并不理想。
In this paper the static pressure uniformity in the static pressure chamber of supply air duct is studied by means of experiments, and its coefficient is derived.
