【摘要】 地层初始温度是地源热泵系统优化设计与运行评价的基础参数之一。现有的测试地层初始温度的方法各有利弊,对规范推荐的布置测温线方法的不足进行了改进,采用整体封装式温度传感器可扬长避短。通过工程实例,对获得的数据进行分析,得到了地层初始温度恢复的具体时间,给出了试验孔成孔后的静置时间的建议值和地层初始平均温度的确定方法,并且证明了新方法的可靠性和精确性。更多还原

【Abstract】 The initial temperature of formation is one of the basic parameters for optimization design and operation evaluation of ground-source heat pump system.The existing methods for initial temperature testing have both advantages and disadvantages.We improve the temperature-testing-line anangement method which is presented by the technical standard.Using the whole packaged temperature sensors can enhance advantage and avoid disadvantage.Through the analysis of the obtaining data from a project case,we get the specific time of restored of the initial temperature of formation.Borehole standing time,and the method to obtain initial average temperature of a thermal response test boreholes are recommended.The new method is proved to be reliable and accurate through an engineering application.更多还原
