| 摘 要： | 以夏热冬暖地区富水土壤砂质土为传热介质,进行了水渗流对其传热特性影响的实验模拟研究。结果表明,无论是在制热还是制冷工况下,渗流都对换热器周围温度场产生显著影响,有渗流情况的换热效果明显提高,热量(冷量)聚集效应明显减弱。在渗流速度较大的富水地区,在保证常规换热效果的情况下,管井间距可适当减小,或在同样管井间距下,可减少管井数量或减小埋管长度。

| Abstract: | Taking the aqueous sandy soil in hot summer and warm winter area as a heat transfer medium,studies the influence of seepage on heat transfer characteristics of the soil by a simulating experiment.The results show that seepage affects the temperature distribution around the heat exchanger obviously in both heating and cooling conditions,and the heat transfer effect is improved markedly at seepage situation,while the accumulating effect of heat quantity is significantly weakened.It is suggested that in the regions of aqueous soil with faster seepage velocity,either the tube-wells can be spaced adequately closer or for the same spacing the number of tube-wells and length of tubes can be reduced under the condition of assuring regular heat transfer effect. |
