Abstract: Benefit from its high material property, carbon fiber is widely applied in industry. In the cooling tower industry, the tower's performance degrades by lack of air volume especially in high temperature seasons. A high performance carbon fiber fan is installed in one tower of 1st water circulating system, from comparison with lateral tower and with the data before the new fan installed, this article confirms that improving the cooling tower's performance with this method is feasible.

Key words: cooling tower, carbon fiber fan, air volume
