摘 要: 采用能量平衡的方法建立了土壤层内U型管桩埋换热器稳态传热模型,并以天津市一地源热泵实际工程为背景,模拟计算了管脚热影响因子、土壤导热系数等对U型管桩埋换热器的传热特性的影响。 The steady heat transfer model for the U-pipe pile heat exchanger in the soil was established using the method of the energy conservation. The thermal characteristic of the U-pipe pile heat exchanger versus the thermal interference of pipe legs and thermal properties of soil based upon the application of the ground source heat pump engineering in Tianjin was calculated.
