建立了地下管网群的传热模型，研究了冷热负荷不平衡对地热田的影响。结果表明，在整个运行期内，土壤平均温度与系统向土壤提供的总热流量之间近似呈线性关系。春、秋季土壤温度恢复率小于热通量恢复率。模拟结果表明，当冷热负荷为0.5，钻孔热流密度在夏季为60 w/m，冬季为-40w/m时，系统运行12个月，每天运行10 h后，钻孔周围土壤平均温度将升高0.48°C，土壤闭孔温度将比初始土壤平均温度17.6°C升高1.3°C，使土壤源热泵不能有效地长期运行。研究结果可为地源热泵的设计和长期运行提供参考。
This paper developed a heat transfer model of the underground pipe group to study the effect of cooling and heating load imbalance to geothermal field. The results show that, there are the approximate linear relationship between average soil temperature and the total heat flow provided by GSHP system to the soil during the whole running period. The temperature of soil restoration ratio is less than the heat flux ration in the spring and autumn. Simulation results show that when heating/ cooling load equal to 0.5 and the heating flux for the bore hole are 60w/m and -40w/m in the Summer and Winter respectively, after this system run 12 months and 10 hours every day, the average soil temperature around borehole will increase 0.48°C, and the soil close borehole temperature will increase 1.3°C than the initial soil average temperature with the value of 17.6°C, which make GSHP not be efficiently for long term running. The results is hoped to be useful for GSHP design and long term running.
