摘　　要：通过实验研究了螺旋型空气分布器的常温射流特性，进行了不同送风角度条件下，空气分布器射流的包络面、主流区速度分布特性的实验。结果表明，送风射程随着送风风量和送风角度的增加而增大，送风风量对送风宽度的影响不是随着风量的增大而增大或者减小，送风宽度随着扇叶角度的增大而整体呈减小的趋势；使得送风均匀性的扇叶角度在0°～10°。An experimental study was conducted on jet characteristics of a spiral air diffuser at normal temperature. The jet envelop, jet core velocity degeneration characteristics and the main airflow velocity distributions were measured in the condition of different jet angle. Analysis the result may lead to the following conclusions： With the increasing the airflow and the jet angle, the penetration depth will increase. The effect of the jet angle on the penetration depth is not monotone. The optimal discharge angle may be between 0°- 10°.
