모듈러 데이터센터에 적용된 직접식 외기냉방시스템의 다양한 제어기법에 관한 연구

Abstract

The main purpose of this research is to analyze various direct air-side economizer control strategies for a modular data center inrespect to air-conditioning energy savings. Considering the fact that the reliability of electronics is the first priority in data centers,we set appropriate four air-side economizer control strategies and conducted annual energy simulation for the purpose ofquantitative comparison. To the results, enthalpy-based air-side economizer showed best energy performance with 54.5% savingscompared to reference system while there is limitation in physical configuration. On the other hand, ultrasonic humidifier assistedtemperature based economizer represented good energy savings of 51% compared to reference with general physical configuration.
