| 摘 要： | 在岩土地下换热器G函数理论的基础上,建立地源热泵热力系统模拟计算模型,提出了基于模型的系统长期运行状况分析方法。以严寒地区为例研究了近三年冬季供暖过程运行状况,模拟分析了地下换热器进、出口流体温度变化规律、热泵机组能效比和系统能耗特性,并与实测结果进行了对比。结果证明了模型及分析方法可行,可为进一步开展更广泛的预测分析提供有效途径。 |

| Abstract: | A simulation model was built for the thermodynamic system of the ground source heat pump(GSHP) based on the G-function theory of the underground heat exchanger(UGHE),and an analysis method for the long-term operation of the GSHP system was proposed.Taking the severe cold region as example,the system winter heating operation conditions in the last 3 years were studied.The fluid temperature variations at the inlet and the outlet of the UGHE,the coefficient of performance and the energy consumption of the heat pump and the system were analyzed simulationally and the results were compared with the measured data.The results show that the model and method are feasible,providing an effective approach for further forecast and analysis. |
| Keywords: | thermal engineering ground source heat pump (GSHP) underground heat exchanger(UGHE) operation station |
