摘要
在使用土壤源热泵的系统中,因地埋管布置形式的不同,土壤源热泵系统对地下温度场的影响也不同。结合Fluent与TRNSYS模拟软件,在排除管群之间热作用影响的条件下,从钻孔间距、钻孔数量、钻孔深度这些影响因素出发,研究土壤源热泵系统运行1a后土壤温度场的分布情况。结果表明:改变钻孔间距对土壤平均温度的影响要大于改变钻孔数量以及钻孔深度。
The arrangement of underground heat exchangers has different influence on the average temperature of the soil in the system of the ground source heat pump. Combined with Fluent and TRNSYS simulation software,starting from the influence factors of borehole spacing,numbers and depth of the drill holes,this paper analyses the distribution of soil temperature in one year after the operation of the ground source heat pump system,without the condition of the heat effect between the pipe group. Results showthat the influence of changing borehole spacing on the average temperature of the soil is greater than the change of the numbers and depth of the drill hole.
