Description

Data Center Energy Efficiency Operating System Supplying Latent Heat to Devices Using Liquid Immersion Cooling System The present invention relates to a data center energy efficiency operation system, and more specifically, to a data center energy efficiency operation system using an immersion cooling system that can efficiently operate the energy of a data center by reducing the atmospheric release of heat generated from server computers in a data center using an immersion cooling system and by supplying the latent heat obtained from the refrigerant to thermal energy-using equipment for recycling. With the development of the Information Technology (IT) industry, public institutions and various companies are establishing large-scale IT infrastructure to provide various IT services. For instance, servers are installed to support file management, data storage, and program operation, or to share hardware resources such as fax machines, printers, and various electronic devices, providing diverse services to multiple clients connected to the servers. In this process, servers establish networks by connecting computers and manage large amounts of storage space. A data center refers to a building or facility that provides servers and network lines. Data centers are generally installed in multi-story high-rise buildings, and are structured such that cages are installed in groups on each floor, multiple racks are installed inside them, and switches are placed in each rack to connect multiple server computers. For such data centers to provide uninterrupted services, stable power supply, internet connectivity, and security are crucial. In particular, since the server computers installed in data centers emit a significant amount of heat, they must be cooled and maintained within a specific temperature range to ensure stable service delivery. However, conventional data center cooling systems absorb heat emitted from server computers and release it into the atmosphere, which not only contributes to global warming but also results in the wasteful failure to utilize the thermal energy generated within the data centers.
