摘要
以某城市更新背景下的商业综合体为研究对象,根据线热源理论,分别对单井系统和多井系统地下埋管周围土壤温度进行了数值模拟,运用叠加原理计算了采取顺排3×3的多井系统在恒热流、变热流密度下地埋管区域的温度场分布,对比了多井系统管群中间区域和边缘区域的温度分布,以及各井的进出口温度,为城市更新项目的地埋管地源热泵系统设计与施工提供理论依据。
Taking a commercial complex under the background of urban renewal as the research object,according to the line heat source theory,numerical simulations are conducted on the soil temperature surrounding the underground buried pipes of single-well system and multi-well system,and the temperature field distribution of the underground buried pipe area of the multi-well system with 3×3 row arrangement under constant heat flow and variable heat flow density is calculated by using the superposition principle.The temperature distribution in the central area and the edge area of the pipe group in the multi-well system,as well as the inlet and outlet temperature of each well,are compared,which provides a theoretical basis for the design and construction of the ground-source heat pump system in urban renewal projects.
