The ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) Technical Committee published the 5th edition of their Thermal Guidelines for Data Processing Environments in March 2021. Elbert Raben van <\/strong>Rittal<\/a> is in <\/strong>his presentation<\/a> extensively discusses the changes\/updates in this edition, where the most important change concerns the recommended relative humidity in relation to corrosive gases in data centers, server and computer rooms.<\/strong><\/p>\r\n

In addition to the usual clarifications, updates, and corrections, the primary updates address air-cooled relative humidity limits, the addition of a new air-cooled class for high-density computing equipment, and several major updates to the liquid cooling chapter.<\/p>\r\n

In October 2019, ASHRAE TC 9.9 published the results of Research Project 1755 (RP-1755), Impact of Gaseous Contamination and High Humidity on the Reliable Operation of Information Technology Equipment in Data Centers. That's quite a mouthful, but what does it mean? In summary, this is a research project focusing on the effect of various gas phase contaminants on silver and copper corrosion in combination with different levels of elevated relative humidity.<\/p>\r\n

After the presentation by Elbert Raben from Rittal, you will be fully informed about the new ASHRAE standard, which will certainly be useful to you in your daily work!<\/p>\r\n
