                摘要:

                以上海市某中型实际地埋管地源热泵工程为例,建立了三维非稳态管群传热模型,并通过监测数据对该模型进行了验证。应用传热模型,计算了系统运行5 a后埋管区地温及管内流体平均温度的变化。探讨了不同运行策略对埋管区岩土体温度及管内流体平均温度的影响,提出了系统长期运行的最优方案。

                Abstract:

                Taking a medium sized ground source heat pump project in Shanghai as an example, develops a three dimensional unsteady state heat transfer model and verifies the model by monitoring data. Calculates the ground temperature and average fluid temperature of  buried pipes after five years operation based on the heat transfer model. Discusses the effect of different operation strategies on the ground temperature and the average fluid temperature, and presents an optimal scheme for long-term operation of the system.
