Outline
To address the problems of high energy consumption and lagging thermal environment regulation in traditional air-conditioning systems of metro stations, this study proposes a dynamic thermal environment management system integrating nature-like wind technology with spatially gridded monitoring, CFD pre-simulation, and equipment-linked control. In the reconstruction project of Nanhu Station of Nanning Rail Transit Line 1, 45 sensors were deployed to construct a gridded monitoring network, and the layout of monitoring points and fan positions was optimized based on CFD pre-simulation. A hierarchical control strategy centered on perceived temperature was developed to realize the intelligent linkage between air conditioners and nature-like wind fans, so as to achieve the energy-saving effect of the air conditioning system. The results show that when the ambient temperature rises to 29℃, the system enhances turbulent heat dissipation (wind speed 0.8–2.5 m/s), making the perceived temperature equivalent to 27℃; the PMV value drops to 0.8–1.2 (PPD≤19%), and the comprehensive energy-saving rate in the air conditioning season reaches 32.1%. The system provides a replicable technical pathway for the green renovation of metro stations.
