HOW CHILLED WATER SYSTEMS MEET DATA CENTRE AVAILABILITY AND SUSTAINABILITY GOALS

The data centre industry continues to develop larger data centres to meet capacity demands , while at the same time taking steps to significantly reduce the impact of data centres on the environment . Companies like Vertiv design with sustainability in mind , developing data centre solutions that help meet the needs of the present without compromising the ability of future generations to meet their own needs .

Cooling systems , and in particular , chilled water systems can play an important role in this evolution . They allow owners and operators to develop new data centres that efficiently address both direct and indirect emissions , which are factored into the total equivalent warming impact ( TEWI ) metric .
Today ’ s chilled water systems reduce direct emissions by limiting the amount of refrigerant used compared to other technologies and enabling the use of new , greener refrigerant types available in the market . These systems also reduce indirect emissions when they adopt new technologies and the system is optimised via best practices regarding system control , which are described in this paper .
The ability of a chilled water system to drive down both direct and indirect emissions can help critical facility operators to achieve a lower TEWI . Chilled water systems can also effectively balance water and energy usage for efficient cooling systems to support a low water usage effectiveness ( WUE , as defined by the Green Grid ). � www . intelligentdatacentres . com
