地源热泵耦合地埋管换热计算若干问题的研究

Study on design calculation of heat exchange for ground-source heat pump buried pipes

针对地质构造特点,进行地下一定深度的温度场测试;对耦合地埋管的换热设计计算中的若干问题进行了研究;在简化计算换热模型的基础上,在Excel上用VBA编写宏功能,得到实用的地埋管换热的工程设计计算方法,是一种工程易用的计算软件。同时将这种计算方法应用到了一个实际工程中,并对计算结果进行了验证。

Temperature field for some depth under the ground was studied to the geological tectonic features of Wuhan. We studied several problems for design calculation of heat exchange of ground buried pipes. Engineering design for heat exchange of ground buried pipes and an engineering calculation software were acquired by using VB macro function in Excel based on simple calculation model. We applied the calculation methods to an actual project.
