摘要
面对能源与环境日渐紧张的局面,可再生能源的使用成为解决这一问题的有效手段.地下浅层作为地下蓄能与地源热泵的能源库被认为是目前最具清洁环保特征的绿色能源利用技术.本文在分析地下蓄能换热器的传热机理中,提出套管式地下换热器的管内流动与岩土传热耦合的数学模型,在饱和岩土无渗流状况下,分析研究流体出口温度和岩土温度时变动态特性.
With the increasing tension of energy and environment situation, renewable energy utilization is an effective way to solve relative problems. Shallow underground is considered as one of the most clean and environmentally friendly green energy technologies which can be used combination with underground thermal energy storage （UTES） and ground source heat pump （ GSHP）. In the paper, heat transfer characteristics and performance of coaxial tubes underground heat exchanger were analyzed. A heat transfer mode coupling heat transfer of flow in pipe with soil is advanced. Under the condition of no groundwater seepage flow in saturated soil, the outlet temperature of fluid and soil temperature are analyzed to explore the varying -time characteristics.
