The ASHRAE Data Center Weather Report

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) announced that the climate in data centers is going to be warmer as it expands the recommended environmental envelope to improve energy efficiency. In fact, in what would have been considered heresy just a few years ago, it is envisioning and advocating the more common use of non-mechanical (compressor-less) cooling – so called “free cooling” – economizers using ambient air temperatures (within limits) to cool the data center.

The details of the expanded temperature and humidity ranges are going to be released in the soon-to-be-published third edition of the ASHRAE datacom book, “Thermal Guidelines for Data Processing Environments.”
