摘要：
The performance of the cooling tower with engineering modification in a 300MW unit was analyzed. The operational data of two cooling towers that one used the air optimization technology and the other did not were investigated and compared. The results show that air deflectors that are fixed around the inlet of the cooling tower can reduce the adverse effect of cross-winds, have good influence on the uniformity of inlet air and then improve the performance of cooling tower. The relative variation of temperature difference as a new theoretical index was given to evaluate the performance of cooling towers under cross-wind conditions. Suggestions were proposed to evaluate the performance of cooling towers in actual operation.
