摘　　要：介绍了地源水-水热泵全年冬夏暖冷联供的实验结果,分析了系统流量对热泵性能参数的影响,获得了最佳运行流量为1000（L/h）。并实测得到单位管深换热率及埋管的有关性能指标。对比分析了冬季吸热曲线和夏季放热曲线。Introduces the experimental results for Ground- Source water/water Heat Pump,analyzes the effects of the variety flux on system performance coefficients, which showes that the optimal operation flux is 1000(L/h) and provides the heat exchange rate per unit depth of coil,45 - 80(W/m). Compares the exchang - heat - curveline in winter with that in summer,through which showes the advantage of GSHP in mode of heating and cooling on long-period operation.
