This article discusses ways in optimizing the selection and application of free cooling systems, also known as evaporative chilling systems. Free cooling systems can minimize energy costs in buildings. In this system, water is being produced through a cooling tower or closed-circuit cooling tower. To predict the system's number of hours of operation and its energy savings, a load estimate is required. INSET: What Is a Cooling Tower?.
