摘要
地源热泵系统与传统空调系统形式相比增加了地热换热器,地热换热器的合理长度对整个热泵系统的性能有着重要作用。文章讨论了竖直U型埋管的传热模型,得出地下埋管换热器的热阻表达式。利用Matlab语言对地埋管换热器准三维模型进行计算机语言编译,得出地埋管长度计算方法。
Ground-source heat pump systems compared with traditional forms of air conditioning system increased geothermal heat exchangers, reasonable length of geothermal heat exchangers for heat pump system performance as a whole has an important role, The heat transfer model for vertical U-tuble ground was discussed, and expressions of thermal resistance of buried tube heat exchanger were drawn. With the help of Matlab computer language, the three-dimensional model of buried tube heat exchanger was compiled, and the buried pipe length calculations were concluded.
