地铁站台板下空间的迷宫式水蓄冷研究
Research on Labyrinth-Type Water-Based Cold Thermal-Energy Storage in the Space Under Subway-Platform Slabs
摘要
Abstract
Cold thermal-energy storage technology for air conditioning is an important measure to achieve"peak shaving and valley filling".This study proposes a water-based cold thermal-energy storage solution that utilizes the space under metro-platform slabs to create a labyrinth-type cold water-storage tank.To investigate the feasibility of this solution,we first design a scaled-down model experiment based on the Reynolds-number similarity criterion and employ various turbulence models to numerically simulate the cold release and storage processes in a cold-water tank.The accuracies of these turbulence models for such mixed flows are analyzed by comparing the experimental and numerical results.The comparison shows that the large-eddy model is more accurate for modeling turbulent flow in this type of labyrinthine cold water-storage tank with mixed flows.Numerical simulations show that the efficiency of charging and discharging cold thermal energy using labyrinth-type water-based cold thermal storage in the space under metro-platform slabs is approximately 60%.关键词
