The publication of a dedicated Cooling Tower guidebook marks the end of a two-year project where members of the association compiled the most essential information on evaporative cooling, to provide consultants, developers, building operators and investors with a quick and comprehensive reference to this technology. The use of water in cooling processes is as old as mankind yet may provide challenges in notoriously dry environments. The water-energy nexus will be one of many aspects to be discussed at the Cooling Tower Guidebook launch event, which will include an HVACR Leadership Workshop on evaporative cooling.
