为科学、准确地测试地源热泵系统的岩土热物性参数,考虑了热物性的时空变异性、测试数据不确定性,采用随机分析理论和数值方法,在特定测度下,以初始值进行迭代和修正,计算了岩土随机热物性参数的统计特性,并对热响应的连续和离散随机过程进行分析。使用线性回归法统计出了离散数据的随机分布规律,并根据回归直线斜率、截距的物理意义来求解热物性参数,经工程应用检测方法可行。
In order to scientifically and accurately test geothermal parameters of geothermal heat pump systems, considering the spatio-temporal variability of thermal properties and the uncertainty of test data, stochastic analysis theory and numerical method are used to iterate And revised and calculated the statistical properties of stochastic thermo-physical parameters of rock and soil, and analyzed the continuous and discrete random processes of thermal response. The random distribution law of discrete data was calculated by using linear regression method. According to the physical meaning of regression line slope and intercept, the thermophysical parameters were solved and the engineering application of the method was feasible.
