| 摘 要： | 分析了地源热泵地埋管周围岩土热阻的随机性,研究了岩土随机热阻及负荷对地源热泵地埋管换热性能的影响。基于热阻随机分析,提出了地源热泵地埋管的可靠性设计方法,得出了可靠度计算公式。结合工程实例进行计算,并与确定性设计方法进行了对比分析。计算结果表明,岩土热阻的变异性对地源热泵地埋管的设计影响较大,可靠性理论对地源热泵地埋管的随机传热性能研究有重要意义。

| Abstract: | In this paper the random characteristic on geotechnical thermal resistance of rock-soil around buried pipe of ground source heat pump(GSHP) is analyzed,the influence on property of GSHP due to random thermal resistance and load also were studied.Based on random thermal resistance analysis,a practical reliability design method to GSHP is proposed,at the same time,a reliability calculate formula is given.The comparative analysis is made with both determinate and reliability designs by using engineering exampl... |
