Optimal placement analysis of cooling tower of a centralized cooling project in Shenzhen

Analyses the optimal placement of the cooling tower of a centralized cooling project in Shenzhen using CFD method. On the basis of the original design scheme, puts forward three kinds of optimal schemes, and carries out the analysis and comparison. The results show that the reflux rate can reduce by 32.6% when the cooling tower is arranged in parallel to the air flow direction and the reflux rate can reduce by 55.8% when the air vent and top mounting baffle are installed at the air outlet of the cooling tower. The top surface shape of the cooling tower can reduce the reflux rate to a certain extent, but at the same time it will increase the wind resistance of the cooling tower, which should be considered in its layout.
