Abstract A thermal response test (TRT) on a borehole evaluates ground and borehole properties, which are needed in the design of borehole fields for ground source heat pump systems. Variation in the heat input rate during a TRT complicates the data analysis, when the electrical power to the test equipment is unintentionally interrupted, or other unwanted changes in the power supply occur. Then, the measured transient temperature curve is a convolution of the varying rate and the constant-unit-rate response function. A deconvolution method has been developed to determine the borehole temperature response that would have occurred if the heat input rate would have remained fixed. The deconvolution technique and the conventional temporal superposition method are validated with TRT data sets with interruptions carried out in a laboratory sandbox. The methods are also applied to field TRT data sets. The deconvolution method has the advantage of generating a smoothed temperature derivative curve, which is used to identify three distinct time periods during a TRT to enhance the analysis.

用于埋管换热器热响应测试的解卷积和卷积方法

摘要 钻孔热响应测试 (TRT) 可评估地面和钻孔特性，这是地源热泵系统钻孔场设计所需的。TRT 期间热输入速率的变化使数据分析复杂化，当测试设备的电源意外中断或电源发生其他不需要的变化时。然后，测得的瞬态温度曲线是变化速率和恒定单位速率响应函数的卷积。已经开发出一种解卷积方法来确定如果热输入速率保持固定会发生的钻孔温度响应。反卷积技术和传统的时间叠加方法通过在实验室沙箱中进行中断的 TRT 数据集进行验证。这些方法也适用于现场 TRT 数据集。解卷积方法的优点是生成平滑的温度导数曲线，用于识别 TRT 期间的三个不同时间段以增强分析。
