澳门金莎娱乐网站

Core technology

● High-efficiency low-noise blade

The blade adopts through-flow calculation and continuous improvement of iteration technology, which improves efficiency, enlarges the range of high-efficiency area, and reduces rotating noise and eddy current noise. The maximum total pressure efficiency reaches the national Class I energy efficiency standard and is 3-5dB lower than the standard limit value of A-weighted sound level.

● Reasonable flow channel design

The dome and the rear guide vanes matched with the blade shape form a reasonable flow channel structure, which can improve the total pressure efficiency by 3% - 5%.
