地源热泵地热响应测试影响因素分析

Analysis of Factors of Thermal Response Test of Ground Source Heat Pump

利用TRNSYS软件建立地热响应测试的模型,以单U型地埋管换热器为例,进行了不同埋深、不同流速、季节效应情况下的地埋管换热量及每延米换热量进行模拟。分析在同一土壤类型条件下,不同地热响应测试工况对测试结果的影响。在地源热泵系统设计过程中应充分考虑这些因素,优化系统设计。

UsingTRNSYSsoftware to establish model of geothermal response test, heat transfer and heat exchange per meter in different depth, different flow velocity and in different seasons were simulated, which took the single-U type ground heat exchanger as an example. Different working condition of geothermal response test's influence on the test results under the condition of the same soil type was analyzed. In ground source heat pump system design process, these factors should be considered for the optimization of design.
