This invention discloses a low-carbon control method for the linkage of waste heat recovery and air conditioning system in data centers, relating to the field of energy-saving and low-carbon control technology for data centers. The specific steps of this method are as follows: S1, collecting real-time and historical operating data of server racks, central cold and heat sources, pipe networks, outdoor environment, and power grid, standardizing and cleaning them to form a full-chain thermal state dataset; S2, using the full-chain thermal state dataset from step S1 to build a time-series neural network for prediction. The prediction model input layer receives the time-series sequence of server rack computing power load, the time-series sequence of server rack waste heat medium temperature and flow rate, and the time-series sequence of outdoor temperature and humidity as input features to predict future operating parameters. This invention constructs a complete thermal state dataset through full-chain multi-dimensional data collection and standardized processing, combined with a rolling time-series prediction model to predict the changing trends of server room heat, heat exchange, and outdoor environment in advance, and dynamically divides the waste heat value time period based on the waste heat value quantification model to form a global cold and heat resource prediction system.
