基于全工况范围进行优化，可以在保证设计点性能的同时有效拓宽模型级运行范

Optimizing based on the full working condition range can effectively broaden the model-level operating range while ensuring the performance of the design point; the combined optimization strategy of the pressure drop constraint of the small flow working condition and the efficiency optimization of the design working condition and the large flow working condition can be further improved Pressure drop margin in the small flow area.

Based on the whole operating range optimization, it can effectively widen the model-level operating range while ensuring the performance of the design point, and the combined optimization strategy of using the pressure drop constraint of small flow condition and the optimization of design condition and high flow condition efficiency can further improve the pressure reduction margin of the small flow area.

The optimization based on the whole operating range can effectively expand the model level operating range while ensuring the performance of the design point; The pressure drop margin of small flow area can be further improved by using the combination optimization strategy of pressure drop constraint under small flow condition and efficiency optimization under design condition and large flow condition.<br>
