摘　　要：对两种空调用贯流风机在变转速下的气动性能变化做了试验研究。得出在大流量区域 ,转速不同对空调用贯流风机的无因次性能曲线影响较小 ,在小流量区域 ,影响较大的结论。Experimental study is done on aerodynamic perf ormance transformation of cross flow fan for two kinds of air_conditioners under the va riable speed. The conclusion is obtained that the variable speed to the effect o f non_dimensional performace curves of cross flow fan for air_conditioner in th e high flowrate area is very little, but in the low flowrate area, it is great. It is recommended that not using the non_dimmensional performance curves to infe r the characteristic curves of cross flow fan under various operating speeds.
