Data centres in Singapore and Malaysia are too cold: Enlogic

Increasing the baseline temperatures in data centres will help reduce energy costs.

Data centre operators in Singapore and Malaysia are over-cooling their facilities, so says a survey conducted by intelligent power distribution unit (PDU) provider, Enlogic. 

At the Datacenter Dynamics conference held in Kuala Lumpur last May and in Singapore last October, Enlogic polled a total of 55 data centre professionals to gauge the operating temperatures of their data centre facilities. Not surprisingly, most of them were running their facilities at temperatures below the range recommended by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Eighty-two percent of the respondents ran their data centres at temperatures below 25 degrees Celsius while 15 percent of them operated their facilities at temperatures below 20 degree Celsius.

The recommended operating temperatures for class one data centres should range from 25 to 27 degree Celsius, with an upper limit of 32 degrees Celsius, according to ASHRAE. While there is no global standard guideline for cooling data centres, ASHRAE's guideline has been commonly referred to by most data centre operators, said Eddie Desouza, Enlogic's Asia Pacific head of business operations.

Not surprisingly, those data centres were consuming energy beyond their reasonable operating conditions.

As intelligent PDUs today can "withstand temperatures of up to 60 degrees Celsius," data centre operators should increase the baseline temperatures in their facilities, said Desouza. "Severe over-cooling [will only lead to] needless energy costs and reduces power utilisation efficiency," he added.
