摘要(Abstract)：

由于动物兽舍洞口为敞开式,围护结构保温性能较差,导致动物兽舍耗热量大,兽舍温度低,为达到兽舍需求的温度,并减少常规能源消耗,文章以狼兽舍为例,通过DeST软件对狼兽舍热负荷进行模拟分析,根据提出的峰值热负荷标准值以及土壤热物性参数计算打井深度及数量。利用TRNSYS软件分别模拟地源热泵系统在井间距5,6,7 m时的系统运行情况和土壤温度变化,结果表明当井间距为5 m和6 m时,土壤温度较低,无法满足系统长时间运行,当井间距为7 m时,土壤温度稳定在14.5℃,源测回水最低温度为6.03℃,供回水温差为4℃左右,系统运行效果最佳。因此对于狼兽舍土壤源热泵系统,满足供热需求的最佳井间距为7 m,井深为100 m,打井数量为20。研究结果为解决兽舍耗热量大,温度低等问题提供了解决方案,应用前景广阔。
