The study of the effect of water vapour on soil heat and moisture migration patterns at different heat source temperatures is of great significance for the application of soil heat storage and ground source heat pump technology. In this paper, a numerical model of one-dimensional unsaturated soil water-vapour-thermal coupling migration was constructed by Hydrus-1D software, and the numerical simulation study of sandy soils with and without water vapour migration at different heat source temperatures was carried out. The results show that for soil heat migration, taking into account water vapour migration increases the radius of influence of the heat source from 60 cm to 78 cm, an increase of 30%; For soil moisture migration, the radius of influence of the heat source increases from 78 cm to 100 cm, an increase of 28.21%. Compared with not considering water vapor migration, considering water vapor migration can reduce the temperature loss during soil heat storage, and the decrease of temperature loss increases with the increase of heat source temperature. When the temperature of the heat source is above 70 ℃, the temperature and moisture fields of the soil change unsteadily and dryness may occur in the vicinity of the heat source.

研究不同热源温度下水蒸气对土壤热湿迁移规律的影响,对土壤储热和地源热泵技术的应用具有重要意义。为此,利用Hydrus-1D软件构建一维非饱和土壤水—汽—热耦合迁移数值模型,模拟研究了不同热源温度下砂土在水蒸气影响下的迁移变化规律。结果表明,对土壤热量迁移,考虑到水蒸气迁移可使热源影响半径由60 cm增大到78 cm,提升30%;对土壤水分迁移,则可使热源影响半径由78 cm增大到100 cm,提升28.21%。与不考虑水蒸气迁移相比,考虑到水蒸气迁移可减少土壤储热过程中温度的损耗,且其温度损耗减少增幅随热源温度的增大而增大。当热源温度高于70 ℃时,土壤的温度场和湿度场变化不稳定,且热源附近可能会出现干枯现象。

研究不同热源温度下水蒸气对土壤热湿迁移规律的影响,对土壤储热和地源热泵技术的应用具有重要意义。为此,利用Hydrus-1D软件构建一维非饱和土壤水—汽—热耦合迁移数值模型,模拟研究了不同热源温度下砂土在水蒸气影响下的迁移变化规律。结果表明,对土壤热量迁移,考虑到水蒸气迁移可使热源影响半径由60 cm增大到78 cm,提升30%;对土壤水分迁移,则可使热源影响半径由78 cm增大到100 cm,提升28.21%。与不考虑水蒸气迁移相比,考虑到水蒸气迁移可减少土壤储热过程中温度的损耗,且其温度损耗减少增幅随热源温度的增大而增大。当热源温度高于70 ℃时,土壤的温度场和湿度场变化不稳定,且热源附近可能会出现干枯现象。

The study of the effect of water vapour on soil heat and moisture migration patterns at different heat source temperatures is of great significance for the application of soil heat storage and ground source heat pump technology. In this paper, a numerical model of one-dimensional unsaturated soil water-vapour-thermal coupling migration was constructed by Hydrus-1D software, and the numerical simulation study of sandy soils with and without water vapour migration at different heat source temperatures was carried out. The results show that for soil heat migration, taking into account water vapour migration increases the radius of influence of the heat source from 60 cm to 78 cm, an increase of 30%; For soil moisture migration, the radius of influence of the heat source increases from 78 cm to 100 cm, an increase of 28.21%. Compared with not considering water vapor migration, considering water vapor migration can reduce the temperature loss during soil heat storage, and the decrease of temperature loss increases with the increase of heat source temperature. When the temperature of the heat source is above 70 ℃, the temperature and moisture fields of the soil change unsteadily and dryness may occur in the vicinity of the heat source.
