Abstract

The main purpose of this paper is to analyze energy saving potentials of various economizers in modular data center by thermal conditions and locations in response to explosive IT demand and data centers' energy consumption increase. To investigate holistic energy saving potentials, various server thermal characteristics, economizers, and locations are analyzed on a modular data center. As a results, economizers can save cooling coil load 75-100% according to their running conditions, and indirect air-side economizer showed better performance than direct air-side economizer. Even though there is more chiller energy saving with server inlet temperature increase, total energy saving decreased more sharply due to fan energy increase. Furthermore, there should be more energy saving potentials in high latitude climates regardless of type of economizers.
