摘要
现有的土壤传热模型忽略了水分迁移对传热的影响,根据质量与能量守恒原理,在原有的垂直埋管土壤源热泵一维线源模型上发展了传热传湿数学模型,并对模型中土壤的各参数进行了分析,为下一步的数值模拟计算以及进一步研究土壤含水率对传热影响奠定基础。
One of the primary assumptions made in the present soil heat transfer approach is that only heat conduction but no moisture is considered. Based on the law of mass and energy conservation, a heat and moisture transfer line source model for the ground-source heat pump system was developed. The work is the basis for the following simulation study on the influence of the soil humidity on heat transfer.
