One of the most common engineering systems supporting both commercial and industrial sites is the cooling tower. Whether by supporting air conditioning or process water cooling, cooling towers are a vital aspect of the process they serve. Cooling towers require significant amounts of energy to function their pump and fan systems. Often, these systems are not operated as efficiently as possible due to the difficulty in calculating savings for a cooling tower energy efficiency project. In this paper, a cooling tower modeling tool is validated that allows industries to readily analyze the energy savings, carbon dioxide emission reduction along with payback period for their cooling tower's potential opportunities. These projects can include savings in fan power use, pumping power use, and water use among others. The projects are analyzed on an hourly basis by importing the hourly Typical Meteorological Year 3 (TMY3) data for the specified region. This makes the calculations from the program extremely reliable as a base case for energy savings projects. Various parameters can be controlled such as variable frequency on the fan or pump, drift eliminators, and water flowrate control, among other differentiating characteristics of their cooling tower to more accurately model it. In this paper, a field validation study will be performed utilizing field data of an industrial cooling tower, under varying circumstances. Finally, energy saving results, carbon dioxide reduction and project economics will be discussed and analyzed.
