摘要
通过将低温余热技术与地源热泵技术结合起来,构建低温余热蓄热型地源热泵系统。通过数值仿真方法研究了低温余热蓄热型地源热泵系统运行温度场的变化特性。研究结果表明,该系统运行一年后,土壤平均温度上升了0.32℃,有效解决了地源热泵在北方地区应用时土壤全年蓄释热总量严重不平衡的问题,为地源热泵技术的发展提供新思路。
Low temperature waste heat technology and ground source heat pump technology are combined to build low-temperature waste heat and heat storage type ground source heat pump system. The change characteristics of temperature field in the low-temperature waste heat and heat storage type ground source heat pump was studied by numerical simulation. The research results showed that the average temperature of the soil increased by 0. 32 ℃ after a year＇s operation. It effectively solved the problem of serious imbalance of total heat storage and release in the whole year when the ground source heat pump was applied in the north area,and provided new ideas for the development of ground source heat pump technology.
