Abstract

This paper presents a package of Modelica models, which are dedicated to data center cooling systems and recently added to the Modelica Buildings library. To demonstrate the usage of this package, we modeled a chilled water system with an integrated wateside economizer, and an air-cooled direct expansion system with an airside economizer. These models are then applied to evaluate the control performance. After that we performed a detailed comparison in terms of system-level energy efficiency, economizing hours and supply air conditions for the two cooling systems. The advantages and disadvantages of this package are finally summarized and discussed.
