摘　　要：地下建筑地源热泵系统向地下释放的热量常大于所提取的热量,容易造成地埋管区域的热量累积,影响其正常使用。因此,提高地埋管换热器效率,减弱冷热量失衡影响,是地下隐蔽工程应用地源热泵系统亟需解决的问题。文章基于换热器温差场均匀性原则,采用全局优化遗传算法,优化了地埋管换热器管群布置。结果表明:与传统等间距方案相比,优化布置后,16、25个钻孔方案的平均无因次温变热阻分别降低了13.8%和53.3%,平均换热效率分别提高了3.76%和5.74%,即钻孔数量越多,换热效率提升越明显。The Ground-source Heat Pump(GHP)systems in underground structures often release more heat into the ground than they extracts,leading to heat accumulation that can impair their functionality.Therefore,enhancing the efficiency of the Ground Heat Exchanger(GHE)and mitigating the effects of thermal imbalances are critical challenges in the application of GHP systems in concealed underground projects.This study employs a global optimization genetic algorithm to optimize the layout of the GHE,guided by the principle of uniform temperature difference field.The results indicate that the optimized layouts with 16 and 25 boreholes respectively reduce the average dimensionless thermal resistance by 13.8%and 53.3%,and increse the heat transfer efficiency by 3.76%and 5.74%.The improvement in heat transfer efficiency becomes more pronounced with an increased number of boreholes.
