摘要:
以成都某新建大型动车所检查库为研究对象,采用计算流体力学(CFD)数值模拟方法,对检查库通风降温方案进行研究。通过建立数值模型,运用有限元法进行网格划分、边界条件设置及求解计算,系统分析了检查库内部温度场分布特征。研究结果表明,采用屋顶通风器与多联岗位空调相结合的通风降温方案,可有效改善工作区域热环境,在确保人员热舒适性的同时兼顾操作便捷性。该研究结果可为类似工程项目的通风系统设计提供理论依据和工程参考。
Abstract:
This paper took a newly-built large-scale EMU depot inspection shed in Chengdu as a case study and employed computational fluid dynamics(CFD)numerical simulations to explore suitable ventilation and cooling strategies for inspection shed. By establishing a numerical model, the finite element method was utilized for meshing, boundary condition setting and solution calculation to systematically analyze the temperature field distribution characteristics inside the inspection shed. The research results indicate that a ventilation and cooling solution combining roof ventilators with multi-split air conditioning units can effectively improve the thermal environment in the working area, ensuring thermal comfort for personnel while accommodating operational convenience. The findings of this study can provide theoretical support and engineering references for the design of ventilation systems in similar engineering projects.
