摘要
针对国内各大主流空调企业室外用开式轴流风机的发展趋势,结合Z401系列不同结构叶轮,系统地进行性能试验,详细给出了性能试验的原理,并给出测试得到的外部性能。试验结果显示开式叶轮在根部结构与后缘结构的变化,对整机的性能影响很大。为后期风机叶片优化方向提供依据。
According to the opened axial-flow fan＇s developing trend in the field of air-conditioning, a performance test based on the impellers in Z401 series had been carried out. The principle of the performance test and the external performance are presented in detail in this paper. The test result shows that the variations of the foot edges and the leading edges structure of the opened impeller affect the blade performance apparently. This test also provides a new proof for fan＇s further optimization research.
