Cooling Tower Performance Calculator
Calculate cooling tower effectiveness, approach, and range for thermal performance evaluation
About this calculator
The Cooling Tower Performance Calculator evaluates the thermal efficiency of cooling towers by computing three critical parameters: effectiveness (cooling efficiency percentage), approach (temperature difference between cold water and wet-bulb), and range (temperature drop across the tower). This tool helps HVAC engineers, facility managers, and maintenance professionals optimize cooling system performance, identify operational issues, reduce energy costs, and ensure equipment operates within design specifications for maximum efficiency.
How to use
Enter the hot water inlet temperature, cold water outlet temperature, and ambient wet-bulb temperature into the calculator. The tool will automatically compute the cooling tower's effectiveness percentage, approach temperature, and range temperature. Use these results to assess performance against design specifications and identify optimization opportunities.
Frequently asked questions
What is cooling tower effectiveness?
Effectiveness measures how well a cooling tower performs compared to theoretical maximum cooling, expressed as a percentage of ideal performance.
What does approach temperature indicate?
Approach temperature is the difference between cold water outlet and wet-bulb temperature, indicating how close the tower performs to theoretical limits.
How is cooling tower range calculated?
Range is the temperature difference between hot water inlet and cold water outlet, representing the actual cooling achieved by the tower.
