摘要
为减少太阳能利用中所受的季节性限制,建立计算模型对跨季节蓄热的可行性进行研究。实现跨季节蓄热的方法有很多,如大型蓄水池蓄热、地下含水层蓄热、埋地换热器蓄热等,重点研究用埋地换热器实现太阳能跨季节蓄热。针对在建实际工程项目,在已有实验的基础上,采用专业计算软件,通过计算机模拟分析地下埋管跨季节蓄热的效果,并对合理的运行方式进行预测。模拟结果表明:对地下热储的利用方式不同,地下蓄热场的温度分布及取热效果也不同;冬季取热时,采用交叉运行模式能使蓄存热量得到更为合理和有效的利用,并且更有利于地下蓄热场的温度恢复。结果是基于天津地区的气象参数和土壤特性数据得出的,表明该地跨季节蓄热具有实际可行性。
The seasonal thermal storage of solar energy in aquifer or. underground is studied. A calculation model is established to reduce the restrictions of seasonal heat storage. Based on the experimental data, the structure and effects of energy storing of underground storage are simulated with professional software. Simulation result shows that there are various temperature distribution patterns and effects corresponding to different discharging modes. The crossingmode is most effective for storage usage, and temperature balance of soil. The results are based on the meteorology data and soil features in Tianjin.
