摘　　要：为了探讨地源热泵（GSHP）系统在防护工程的适用性，针对防护工程的空调负荷特点，以变热流圆柱热源模型为基础进行了4种典型工况的传热模拟和分析。研究结果表明：防护工程间歇运行和平均负荷强度低的特点，能有效消除冷热负荷不平衡对土壤温度场的影响，地温恢复能力强，机组运行效率高。高效节能环保的地埋管地源热泵系统在防护工程中有着很好的应用前景。In order to explore the applicability of GSHP （ground-source heat pump） system in protective engineering, based on the variable heat cylindrical source model, a simulation program for U-vertical ground source heat pump was developed. According to air conditioning load characteristics of protective engineering, four typical operating conditions for heat transfer were analyzed. The results show that the characteristics of intermittent operation and low average load in protective engineering can effectively eliminate the load imbalance of hot and cold temperature effects on soil, so the ground temperature recovers quickly, and the unit keeps a high COP. The GSHP system with environmental protection and energy saving would have a very good prospect of application.
