A data center energy efficiency operation system based on the temperature of a circulating refrigerant is disclosed. The data center energy efficiency operation system according to the present invention comprises: a plurality of mount racks including a refrigerant of the liquid immersion cooling method and an electronic component substrate contained in the refrigerant; a refrigerant circulation device that circulates the refrigerant corresponding to each mount rack; a monitoring device that monitors in real time the temperature immediately before the inflow of the refrigerant for each mount rack, the heat generation temperature of the electronic component substrate, and the temperature immediately after the outflow of the refrigerant for each mount rack; and a circulation speed control device that individually controls the circulation speed of the refrigerant for each mount rack based on the temperature immediately before the inflow and the temperature immediately after the outflow of the refrigerant for each mount rack, and the heat generation temperature of the electronic component substrate. The apparatus includes a refrigerant storage device installed corresponding to each mount rack and storing refrigerant discharged from each mount rack; wherein the circulation speed control device accelerates or decelerates the circulation speed of the refrigerant for each mount rack based on the temperature difference between the refrigerant temperature immediately before inflow and the heat generation temperature of the electronic component substrate contained therein, and the temperature difference between the heat generation temperature of the electronic component substrate contained therein and the refrigerant temperature immediately after discharge, and supplies thermal energy from the latent heat of the refrigerant stored in the refrigerant storage device to a registered thermal energy user.

Description

Data Center Energy Efficiency Operation System Based on Temperature of Circulating Refrigerant The present invention relates to a data center energy efficiency operation system, and more specifically, to a data center energy efficiency operation system based on the temperature of a circulating refrigerant that monitors heat generated by server computers and, based on the temperature of the circulating refrigerant, not only maximizes the cooling efficiency of the data center but also utilizes the latent heat of the refrigerant for registered thermal energy users, thereby enabling energy operation at optimal efficiency. 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.
