Computer Room Evaporative Cooling

Perspectives (May 14 2010) Servers

1. I recently came across a nice data center cooling design by Alan Beresford of EcoCooling Ltd. In this approach, EcoCooling replaces the CRAC units with a combined air mover, damper assembly, and evaporative cooler. I’ve been interested by evaporative coolers and their application to data center cooling for years and they are becoming more common in modern data center deployments (e.g. Data Center Efficiency Summit).   An evaporative cooler is a simple device that cools air through taking water through a state change from fluid to vapor. They are incredibly cheap to run and particularly efficient in locals with lower humidity. Evaporative coolers can allow the power intensive process-based cooling to be shut off for large parts of the year. And, when combined with favorable climates or increased data center temperatures can entirely replace air conditioning systems.
