Research on Labyrinth-Type Water-Based Cold Thermal-Energy Storage in the Space Under Subway-Platform Slabs
空调蓄冷技术是实现"削峰填谷"的重要措施,本文提出利用地铁站台板下空间制作迷宫式蓄冷水池的水蓄冷方案.为研究该方案的可行性,首先根据雷诺数相似准则对原模型设计缩尺模型实验,并采用不同湍流模型进行蓄冷水池释冷与蓄冷过程的数值模拟,对比实验与数值模拟结果表明:该类迷宫式蓄冷水池混合流的湍流模型采用大涡模型更为准确.在此基础上,数值模拟结果表明:地铁站台板下空间采用迷宫式水蓄冷的蓄冷与释冷的恒温层体积比约为60%.
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%.
