In a data center, a cooling system is a crucial factor in ensuring uninterrupted operation and quick response to changes in IT services. This study proposes a cooling system based on hot standby sparing (HSP) that can effectively provide redundancy and optimize energy efficiency in data centers with N+1 or more equipment required for reliable uninterrupted operation. The standby strategy adopted for ensuring high reliability in data centers was classified into HSP, warm standby (WSP), and cold standby (CSP). If the cooling system meets the redundancy requirement of N+1 or higher, which is necessary for a dedicated data center, and the configuration of VSD/VFD equipment, then the HSP-based cooling system should be considered first in terms of energy efficiency. Through a case analysis of 30 MW-class large-scale A-data centers, the CSP-based and HSP-based cooling systems were compared. The results showed that the cooling power consumption for the same design capacity was reduced by approximately 15% when applying the HSP-based system compared to the CSP system. The power usage effectiveness (PUE) of the HSP-based cooling system was 1.20, and the cooling energy cost was 163 USD/IT-kW, indicating that the HSP-based system significantly improved energy efficiency. Thus, the HSP-based cooling system is the best strategy for effectively reducing cooling energy without requiring major facility changes or investments.
