均匀送风风管构件流量特性实验
Experimental study on flowing characteristics of uniform ventilation duct component
摘要：
提出了一种新型均匀送风风管构件，将该构件应用于所搭建的实验平台，对构件流量特性及系统的均匀送风特性进行了实验研究。结果表明，风机运行在10～50 Hz时，各风口的风量不平衡率均能维持在5%以内，可实现均匀送风。采用这种形式的构件，在实际长风管空调系统风量调节时，大大降低了调节工作量。

Abstract：
Proposes a new uniform ventilation duct component. In order to investigate the flowing characteristic and the uniformity of air supply, applies the new duct component to the experimental platform. The experimental results show that the unbalance rate maintains below 5% when the fan is running between 10 and 50 Hz, resulting in uniformity of air supply. It can remarkably reduce the cost of adjustment in condition that such design form of component is applied to the actual long duct air conditioning system.
