ABSTRACT
With the acceleration of urbanization, the number of high-rise buildings is increasing rapidly, and the secondary water supply system, as a critical facility for ensuring residents' water usage, has drawn increasing attention to its energy consumption issues. This study aims to explore energy-saving technologies for secondary water supply systems in high-rise buildings and evaluate their practical application effects, thereby providing a scientific basis for optimizing energy utilization and reducing operational costs. By integrating literature analysis with field investigations, the study identifies the primary energy-consuming components of current secondary water supply systems and introduces key improvement technologies, including variable frequency speed control, intelligent control strategies, and novel high-efficiency pumps. Based on a typical high-rise building case, comparative experiments and numerical simulation methods are employed to conduct a detailed analysis of energy consumption data before and after system modifications. The results indicate that by optimizing pump group configurations and implementing precise flow regulation, the overall energy consumption of the system can be reduced by approximately 25%, while significantly enhancing water supply stability and extending equipment lifespan. Additionally, the study proposes a predictive maintenance scheme based on big data analysis, which can further minimize energy waste caused by equipment failures. The innovation of this research lies in the integration of intelligent technologies with traditional water supply systems, establishing a universal energy-saving fr amework adaptable to various types of high-rise buildings, thus offering crucial references for industry standard development and technology promotion. The study demonstrates that the rational application of energy-saving technologies not only effectively reduces the operational costs of secondary water supply systems but also contributes positively to achieving sustainable development goals in the building sector.
