	2.	This paper introduced the experimental results for ground - source water / water heat pump , analyzed the effects of the variety flux on system performance coefficients , which showed that the optimal operation flux is 1000 ( l / h ) and provided the heat exchange rate per unit depth of coil , 45 80 ( w / m ) . compared the exchang - heat - curveline in winter with that in summer , through which showed the advantages of gshp in mode of heating and cooling on long - period operation 本文介绍了地源水-水热泵全年冬夏暖冷联供的实验结果以及过渡季地温的恢复情况，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。
	3.	This experiment include many contents , in a word , that is summer condition experiment , winter condition experiment > summer - winter transition condition experiment and winter - summer transition condition experiment , furthermore summer condition experiment still include flux changing experiment and winter condition experiment still include thermal balance experiment this article dealt with the data of the test , calculating out energy absorbing ( energy discharging ) of buried pipe in winter condition ( summer condition ) , input power of heat pump x heat exchanging of piece buried pipe length x co - efficiency performance ? op ( energy efficiency rate ? er ) and average heat exchanging coefficient ; in additiont this article compares the inlet water temperature and outlet water temperature of underground the first layer and the second layer buried pipe when heat pump was running , the results are that the heat exchanging ability of the second layer buried pipe outgos the first layer buried pipe , and heat exchanging is more stable ; and still analyse earth temperature resuming in the transition season . the results are earth temperature resume fast in the first week when the heat pump runs off 本文测试内容相当多，概括地说就是四个工况的测试，即夏季制冷工况的测试、冬季供热工况的测试、夏?冬过渡季测试和冬?夏过渡季测试；另外在夏季工况的测试中还进行了变流量测试，在冬季工况的测试中还进行了热平衡测试。本文对测试数据进行了处理，计算出了冬(夏)季工况埋管吸(放)热量、热泵空调器供热量(制冷量) 、热泵空调器输入功率、埋管单位管长换热量、供热性能系数(制冷能效比)和平均传热系数等；另外，还比较了热泵运行时地下一二层埋管进出水温度变化情形，得出地下二层埋管换热能力优于地下一层埋管，且换热很稳定；并分析了过渡季地下一二层埋管温度恢复情形，得出热泵系统停机一周内地温恢复特别快。
