Abstract

The primary objective of this paper is to propose the integration of a hot water cooling system with a desiccant-assisted evaporative cooling system for air conditioning a data center. The feasibility of the integrated system is analyzed by a detailed energy simulation for a model data center by using TRNSYS (transient system simulation) 16 with a commercial equation solver program. The energy saving potential of the proposed system is evaluated by comparing it to a conventional air handling system with an air-side economizer serving the model data center.
