摘要
结合土壤源热泵技术推广中存在的问题和地下蓄能技术的优点,提出了土壤蓄热与土壤源热泵集成系统及其地下管群换热器的布置方式。并在能量平衡的基础上建立了地下管群换热器蓄热、释热和停止运行的数学模型。通过数值模拟,分析了埋管间距对蓄热与释热的运行特性的影响。
Combined the advantage of soil thermal storage technologdd and ground-source heat pump,presented a new integrated system as well as designed the plan of underground pipe bundle.Based on the model of energy balance,a mathematic model of soil thermal storage and release process of geothermal heat exchanger was established.The influence of separation among pipes on heat transfer of geothermal heat exchanger was analyzed.
