ASHRAE publishes thermal guideline for liquid cooled data processing environments

September 27, 2011 - ASHRAE has published a vendor-neutral white paper that serves as the thermal guideline for liquid-cooled data processing environments. “2011 Thermal Guidelines for Liquid Cooled Data Processing Environments” creates five data centre classes for liquid-cooling. In addition to the classes, the paper provides insight into other considerations for liquid-cooling, including condensation, operation, water flow rates, pressure, velocity and quality, as well as information on interface connections and infrastructure heat rejection devices. This whitepaper follows an earlier whitepaper released in May 2011, “2011 Thermal Guidelines for Data Processing Environments – Expanded Data Centre Classes and Usage Guidance”.
