be provided according to the product sample of the thermal performance curve is selected.4) provided by the manufacturer of thermal performance curves, such as using simulated test data on the tower, should be based on the simulation test conditions and the design of the tower tower of the differences in operating conditions, to correction of simulation test data of the tower, the correction coefficient is 0.80 ~ 1.00.5) the position of the cooling tower, should keep a certain distance between
