摘要

针对地埋管地源热泵工程应用中出现的地埋管长度设计不合理问题，搭建了地源热泵三维动态仿真平台，将动态模拟的出口温度与规范要求的设计出口温度进行对比，评估地埋管设计长度的合理性。以北京某建筑为应用对象，研究了地埋管设计长度的误差随土壤热物性参数与钻孔相关参数变化的规律，并用敏感性分析法量化了各因素对地埋管长度的影响程度。研究结果表明：随着土壤导热系数、土壤容积热容、钻孔深度、钻孔间距的增加，地埋管设计长度的相对误差逐渐增大。各因素的相对误差变化范围分别为：10.7%~27.3%、8.0%~23.8%、7.3%~12.5%、12.5%~17.4%。土壤导热系数敏感性分析的量化指标的绝对值为0.909，是地埋管长度的显著影响因素，其余因素的影响程度由高到低分别为土壤容积热容、钻孔间距、钻孔排列列数和钻孔深度。

Abstract

To address the issue of unreasonable buried pipe length design in ground-source heat pump projects

a three-dimensional dynamic simulation platform was developed. The reasonableness of the buried pipe length was evaluated by comparing the simulated outlet temperature with the designed outlet temperature based on specifications. Using a building in Beijing as a case study

the effects of soil thermal properties and borehole-related parameters on the design error in buried pipe length were analyzed. A sensitivity analysis further examined the impact of these factors. Results indicate that the relative error in buried pipe design length increases with rising soil thermal conductivity

soil volumetric heat capacity

borehole depth

and borehole spacing. Relative error ranges were 10.7%-27.3%

8.0%-23.8%

7.3%-12.5%

and 12.5%-17.4% for the respective factors. Sensitivity analysis revealed soil thermal conductivity as the most significant factor influencing pipe length

with a quantitative index of 0.909. Other influential factors

in descending order

were soil volumetric heat capacity

borehole spacing

number of borehole columns

and borehole depth.
