| 摘 要： | 采用ANSYS有限元APDL语言进行编程,根据线热源模型,对竖直双U型管地下换热器周围温度场进行模拟,通过模拟分析得到了土壤热物性、管外温度、土壤类型以及回填料等因素对土壤温度场的影响.同时,也说明土壤本身具有很强的恢复能力,对实际工程地埋管换热器的设计有参考价值.

| Abstract: | According to line heat source model,vertical double U-tube ground heat exchanger was simulated by ANSYS using APDL language.Effects on soil temperature field of soil thermal physical properties,external tube temperature,soil type and different material of backfill etc were obtained through the simulation analysis.At the same time,also it shows that the soil itself has a strong ability to recover.They are helpful to further study on the design of underground heat exchanger. |
