地埋管地源热泵气候相对适宜性研究
Relative climate suitability of ground source heat pumps
摘要：
提出以地表年均温度、度时数差值、净辐射量差值及累计过余含湿量为评价指标，采用模糊综合评价方法研究地埋管地源热泵的气候相对适宜性。应用该方法，以长江流域9个城市为例，分析了地埋管地源热泵技术在各个城市的气候相对适宜性排序。结果表明，在长江流域，度时数差值与累计过余含湿量对地埋管地源热泵应用的影响较大，地表年均温度与净辐射量差值的影响则较小。
Abstract：
Taking the mean annual temperature of ground surface, degree-hours difference, net radiation difference and accumulated excess humidity ratio as evaluating indicators, adopts overall fuzzy evaluation method to research relative climate suitability of ground source heat pumps. Taking nine cities in the Yangtze valley as examples, apply the method to analyse the relative climate suitability of ground source heat pumps. The results show that the degree-hours difference and the accumulated excess humidity ratio have more important effect on the application of ground source heat pumps, and the influences of the others are smaller.
