摘要
通过DEST软件模拟出医院住院部全年动态负荷情况,分析了医院建筑负荷的特点。建立土壤源热泵系统地埋管换热物理和数学模型,以FLUENT为分析工具,对该建筑的地源热泵系统进行以运行时间为变量的数值计算分析,得到不同运行时间下的地温和管内流体的温度分布规律。以间歇运行时间为变量,得到辅助冷却模式下地温和管内流体的温度分布规律,提出了医院建筑地埋管地源热泵系统的优化运行模式。
This paper has simulated the annual dynamic load distribution of the hospital by the DEST software, and analyzed the load characteristics of the hospital. Build the heat exchanger tube's physical and mathematical models of the ground source heat pump system, and to run the time for variables, numerical calculation and analysis about the ground source heat pump system of the building through FLUENT, getting the temperature distribution rule of the ground and the tube fluid. With intermittent operation time as a variable, getting the temperature distribution rule of the ground and the tube fluid in auxiliary cooling mode, put forward optimum operation mode of the ground source heat pump system using in hospital building.
