摘要
文中通过将低温余热蓄热技术与地源热泵技术结合起来,运用数值仿真方法对低温余热蓄热型地源热泵系统在连续型余热蓄热边界条件下长期运行特性进行研究。研究结果表明,该系统在连续型余热蓄热情况下运行十年后,土壤平均温度上升了0.36℃,平均相对湿度下降了4.3%地埋管群区域局部土壤出现干涸裂缝状态进而影响传热。
In this paper, low temperature waste heat storage technology and ground source heat pump technology are combined, and numerical simulation methods are used to study the long-term operating characteristics of low temperature waste heat storage type ground source heat pump systems under continuous waste heat storage boundary conditions. The results show that the average soil temperature increased by 0.36℃, and the average relative humidity decreased by 4.3% after operating the system for ten years under continuous waste heat storage Dry soil cracks appeared in the local soil in the buried pipe group area, which affected the heat transfer.
