냉복도 밀폐시스템의 적용에 의한 데이터센터 서버실의 냉방에너지 절감 효과 분석

Abstract

In order to keep the server room temperature condition, energy consumption has been rapidly increased as the increasing internal heat gain of server room in data center. And the cooling units for server systems are fully operated to satisfy the indoor temperature condition, it results in the excessive energy consumption. There are many wastes of cooling energy which is caused by the structural problems in data center server room. For example, a leakage by the electric cable hole, mixing or recirculation of hot air from the hot aisle to the cold aisle, short circulation of the CRAC(Computer Room Air Conditioning), and others. So there are many strategies to reduce the waste of cooling energy in data center. In this study, cold aisle containment system was proposed among the various strategies to reduce the waste energy by recirculation air from the hot aisle. To verify the effectiveness of the cold aisle containment system, test bed which is same with exist server room was set up in IDC(Internet Data Center) building. And comparative experiments, conventional open type cooling system and cold aisle containment sysetm, were carried out in actual conditions. As the result, the range of inlet temperature of server system was 20～25℃ in exist cooling system and the range of inlet temperature dropped below 20℃ by cold aisle containment system. After all, was possible by the cold aisle containment system and cold aisle containment system was proved to be the solution for energy saving cooling system.
