摘要
土壤导热系数的大小直接对土壤源热泵系统中埋地换热器的面积和初投资有显著影响。现场测试法是研究土壤热物性参数最有效的方法之一,结合邢台市沙河收费站地源热泵测试工程实例,介绍了地源热泵热响应测试的测试步骤、测试方法和数据分析。实测结果与传统查手册的结果相比更为准确可靠,为当地地源热泵系统的准确设计提供了依据。
The ground heat exchanger size and cost are directly dependent on the ground thermal conductivity.Field test method is the most effective way to study the soil thermal properties.This paper introduces the ground source heat pump thermal response test of testing procedures,test methods and data analysis,combined with Xingtai shahe toll station ground source heat pump test engineering example.The measured results compared with the traditional manual inspection results,measured results are more accurate and reliable.It is provided for the local ground source heat pump system for theoretical basis.
