地埋管地源热泵系统冬季运行测试研究
Measurement of operation of a GSHP system in winter
摘要：
对武汉市清江花园小区地源热泵空调系统2007—2008年度冬季的运行情况进行了测试，分析了机组与系统的性能系数、地下土壤温度、地埋管换热量以及机组进出口水温等参数的变化。计算结果表明，在武汉地区（夏热冬冷地区）使用地源热泵系统节能效果显著。

Abstract：
Tests the operation conditions of ground-source heat pump(GSHP) system in Qingjianghuayuan residential quarters in winter in 2007-2008, and analyses the variation of the parameters including the COP of the HVAC unit and system, the temperature of the underground soil, the heat transfer of underground tube and the water temperature of the inlet and outlet of the unit. The calculation result shows that the energy saving effect is significant for the GSHP system adopted in Wuhan.
