中深层地埋管地源热泵性能影响因素显著性分析
Significant Analysis of Influencing Factors on Performance of Medium-deep Borehole Ground Source Heat Pump
摘要
Abstract
The heat transfer model of the medi-um-deep borehole heat exchanger is established.The drilling depth,outer pipe specifications,geothermal gra-dient,thermal conductivity of grout material and aver-age thermal conductivity of rock-soil are selected as the influencing factors,the contribution rate of each influ-encing factor is calculated by ANOVA method,and the significance of the influence of a single influencing fac-tor on the performance index of the heat pump unit is evaluated.The drilling depth has the most significant effect on the performance index of the heat pump unit,followed by the geothermal gradient.In engineering practice,if conditions permit,increasing the drilling depth and selecting the locations in areas with high ge-othermal gradients are conducive to the efficient opera-tion of the heat pump unit and reducing energy con-sumption.关键词
