Operational power usage efficiency evaluation of air conditioning equipment in data center rooms

To evaluate the power usage efficiency of air conditioning equipment in data center rooms in different climate zones, determines the maximum design mechanical load component (MLC) in different cities according to meteorological zone of ASHRAE. Taking Shanghai area as an example, measures the energy consumption of three selected typical data center rooms, calculates the MLC in operation and maintenance stage, compares them with maximum design MLC, and analyses whether the power usage efficiency can meet the design requirement. The maximum design MLC can scale the power usage efficiency of air conditioning equipment and guide the desirable operation, maintenance and energy saving retrofitting.
