Gas-liquid phase change carbon dioxide energy comprehensiveutilization system adapted for data center

Abstract

Provided are a gas-liquid phase change carbon dioxide energy comprehensive utilization system adapted for a data center and a control method therefor. The system includes: an energy storage subsystem, the data center, and a heat balance component. The energy storage subsystem includes a gaseous carbon dioxide management unit, an energy storage component, a liquid storage unit, and an energy release component, which are sequentially connected in that order to form a closed loop. The energy release component includes an evaporator. A heat exchange medium inlet of the data center is connected to a heat exchange medium outlet of the evaporator, and a heat exchange medium outlet of the data center is connected to a heat exchange medium inlet of the evaporator. The heat balance component includes a high-temperature transmission pipeline and a low-temperature transmission pipeline. The heat balance component is configured to: when the gas-liquid phase change carbon dioxide energy comprehensive utilization system adapted for the data center is in an operation condition and heat dissipation of the data center is inconsistent with heat supply required by the evaporator, supplement a high-temperature heat exchange medium to the heat exchange medium inlet of the evaporator through the high-temperature transmission pipeline or supplement a low-temperature heat exchange medium to the heat exchange medium inlet of the data center through the low-temperature transmission pipeline. The present invention can realize the comprehensive utilization of energy, reduce investment and operation cost of the system. 1 ABSTRACT
