TP25-25 Managing Water of Adiabatic SystemsAdiabatic coolers are becoming more common in the HVACR marketplace. Multiple designs are employed within the industry using different water system methodologies, the details of which can significantly impact the performance and maintenance requirements for the heat rejection equipment. This paper analyzes some of the pros and cons of the different designs available.
