Performance Characteristics of Internet Data Center Cooling System Utilizing Water Source
Nicholas Lamptey Boafo,Selorm Kwaku Anka,Jong Min Choi 대한설비공학회 2022 대한설비공학회 학술발표대회논문집 Vol.2022 No.6
Internet data centers have grown significantly in recent years as a result of the extensive use of telecommunication and internet systems, and they are already causing energy and environmental challenges. Conventional data centers are usually cooled by air-source vapor compression systems which require an uninterrupted electricity supply all year round. The energy consumption of the space cooling system has been in charge by 30-50% of the total energy delivered to a typical data center. There is rare literature on the use of dam water as a potential heat source for IDC cooling systems. This paper presents a cooling system utilizing deep dam water as a heat source. The basic performance characteristics of the system were experimentally analyzed according to operational methods with emphasis on the variation of entering water temperature. It is observed that the capacity for the two modes increases significantly as the OD EWT falls. Overall system COP in the free cooling mode increased greatly rather than it in the forced cooling mode.
