| 摘 要： | 通过热传导理论,建立了地下土壤初始温度分布的理论计算模型,并将模型的全年模拟结果与全年实测值进行了对比.结果表明,地下土壤温度分布模型的计算值与实测值十分吻合,说明理论模型是正确的.模拟结果表明,当土壤深度达到10 m时,土壤全年温度趋于稳定.该理论模型可应用于土壤源热泵系统的分析和设计中.

| Abstract: | A theoretical model was derived to determine the initial temperature profile of underground soil by heat transfer analysis.A comparison was made between the annual theoretical simulation result and the measured value.The result has shown that the theoretical result has a good agreement with the measured value,and that the theoretical model is accurate and reasonable.The simulation result has revealed that the annual soil temperature trends to be stable when the soil depth is more than 10 m.The theoretical model can be applied to the design and analysis of soil source heat pump system. |

| Keywords: | modeling soil source heat pump soil temperature profile measured values |
