As the scale of data centers continues to expand, the environmental impact of their energy consumption has become a major concern, highlighting the increasing importance of thermal management in data centers. In this study, we address these challenges by adopting the Soft Actor-Critic (SAC) algorithm of reinforcement learning to enhance energy management efficiency. To further improve adaptability to environmental changes and provide a more comprehensive representation of the current state information, we introduce the Dynamic Control Interval SAC (DCI-SAC) structure and combined-value state space. We conducted two groups of simulation experiments to evaluate the performance of SAC and its variants. The first group of experiments showed that in a simulated data center model, SAC achieved energy savings of 32.23%, 9.86%, 10.77%, 6.95%, and 1.83% compared to PID, MPC, DQN, TRPO, and PPO, respectively, demonstrating SAC's superior algorithmic performance. The second group of experiments shows that DCI-SAC with a combined-value state space achieves up to a 6.25% reduction in energy consumption compared to SAC with the same state space. Additionally, it achieves up to a 9.48% reduction in energy consumption to SAC with a final-value state space. These results validate the effectiveness of the DCI-SAC and combined-value state space, showing that both improvements achieve superior energy efficiency and stability in the energy control of liquid-cooled data centers.
