针对太阳能-土壤源热泵非采暖季土壤高温蓄热中的热湿传递现象,搭建一维土壤高温蓄热实验装置,选取砂土和壤土两种不同土质,研究不同蓄热温度和土壤初始含水率条件下,土壤温度场和湿度场随时间和空间的变化趋势以及在两种土质中的差别,探讨和分析热湿传递相互影响规律和作用机理。实验结果表明,砂土比壤土蓄热效果好、速度快。
Aiming at the phenomenon of heat and moisture transfer in high temperature heat storage of solar-earth source heat pump in non-heating season, a one-dimensional high temperature heat storage experimental device was set up. Sand soil and loamy soil were selected to study the influence of different heat storage temperature and soil initial moisture content Under the conditions of soil temperature and humidity field with time and space trends and the difference between the two soil types to explore and analyze the laws of heat and moisture transmission interaction and mechanism of action. The experimental results show that the heat storage effect of sand is better than that of loam and the speed is faster.
