摘　　要：分析了圆柱热源（热汇）理论模型，运用圆柱源理论对太阳能．土壤源联合运行热泵系统进行连续20d运行的状况进行模拟，得出联合运行模式较单独土壤源运行模式节能8％～10％，可为圆柱源理论模型应用和太阳能-土壤源热泵运行模式的选择提供参考。引入“负荷集合”思想对圆柱热源（热汇）理论模型进行改进，使其适合于对土壤源热泵的全年运行进行模拟，模拟过程更为快捷。The cylindrical heat source theory was discussed and a 20 days heat pump system simulation of solar-ground source combined operation was performed utilizing the cylindrical heat source theory. A load aggregation methodology was inducted in order to improving the cylindrical heat source theory. The energy consumption in the case of combined mode is about 8 - 10% less than that of single ground source mode. The fluid from the solar collector to the ground heat exchanger results a higher COP in all three combined modes, which shows that fluid circulation organization improving can raise the system COP.
