Impact on Teaching and Research Dr. Ethan Languri, associate director of the Tennessee Tech IAC, supervised several lead students on the winning project, titled “Evaporative Cooling Tower Efficiency Enhancement.” The first student was Ms. Pallavi Patil, who completed her Master of Science in mechanical engineering based on this IAC funded research. She presented two conference papers and published her thesis titled “Dynamic Modeling and Experimental Analysis of an Induced Draft Cooling Tower” in 2017. The second student was Mr. Travis Howard who completed his degree in 2018 by publishing his thesis titled “Cooling Tower Optimization and Analysis Tool.” His work was continued by Mr. Kade Howard, who performed field data collection and code development on the cooling tower project as a project for his master’s degree in 2020. The final graduate student was Mr. Joshua Hooper, who finalized the cooling tower modelling program (the “Cool Tool”) utilizing the programming language Visual Basic, part of Excel. The “Cool Tool” has been presented to several experts in the field and verified in a number of cases before being presented to IAC team in late 2020.

Tennessee Tech University Industrial Assessment Center (IAC) students and faculty continue to advance their “Cool Tool” Cooling Tower software, which received a Junior Faculty Research Award in 2015. This macro-enabled Excel based tool aims to help facilities enhance the efficiency of their cooling towers through a series of simulations involving a range of variables.

Why Cooling Towers are Important in Industry - The purpose of a cooling tower is to cool down water that has been heated up due to industrial processes or air conditioning condensers. A cooling tower operates as a heat exchanger that allows water and air to come in to contact with each another to lower the temperature of the hot water (see Figure 1). This is achieved mostly through evaporation as the water circulates through the tower. Cooling towers allow industry to reuse cooling water supplied to their process for heat rejection efficiently and inexpensively.

“Cool Tool” is a macro-enabled Excel file that analyzes an annual base case compared to a revised case of a cooling tower operation. The tool simulates 8,760 hourly calculations for fan power for various fan controls, water consumption, and pumping energy consumption and demand based on the user’s location and its corresponding Typical Meteorological Year 3 (TMY3) weather data. “Cool Tool” simulates up to five cooling tower cells as one tower utilizing one pump or parallel pumping. Through a partnership with Oak Ridge National Laboratory (ORNL), researchers incorporated ORNL’s calculation algorithm in analyzing various fan control technologies for cooling towers. The program provides a summary of the projected annual savings for fan power, water, and pumping results based on the user’s inputs for their base and revised cases. “Cool Tool” can help plants analyze ways to save energy and money at their facility through cooling tower modifications, whether they use it for process cooling or Heating Ventilation and Air Conditioning (HVAC) applications. Users will be able to input their entering/leaving water temperatures based on a monthly operating schedule or a wet-bulb temperature schedule. For the simulation, plants will be able to tell the program whether or not their base and revised case has a variable-frequency drive (VFD) on the fan/pump, drift eliminators, changes in cycles of concentration, reduced water flow rate, etc.
