Experimental study on cooling tower outlet water temperature simplified model suitable for online application

For the complexity and low practicality problems in traditional ε-NTU mathematical model of cooling tower outlet water temperature, proposes a simplified model based on convective heat transfer and data fitting, which can effectively reduce the number of test variables and simplify the calculation procedure for a specific cooling water system. Through experimental research, compares the two models. The results show that the accuracy of the simplified model can be controlled less than 5%, meeting the requirements of precision. Meanwhile, the calculation is so simple that it can be used to predict the changes of outlet water temperature under different conditions by test data, which can be applicable to cooling water systems online energy saving control.
