摘要
道路集热蓄能融雪化冰实现夏季太阳能集热的季节性蓄能。在分析路面集热、地下蓄能和融雪化冰复合系统过程基础上,系统研究了道路融雪化冰过程传热现象、传热状态和分析方法。对路面融雪化冰的基本传热过程进行分析,建立了基本的数学模型和传热关系,提出了基于热流体循环流动的路面融雪化冰的基本传热过程控制方程,为进一步的模拟计算分析奠定理论基础。
A hydronic ice-snow melting （HISM） Coupled with slab solar collection （SSC） and thermal energy storage（TES） is a innovate method and is expected to become more prevalent. The system can perform both functions, snow-ice melting in wintertime and seasonal underground thermal energy storage （UTES） in summertime, and it can realize the renewable energy application. The recent work aims to layout the HISM-SC-TES system, and to analyze the phenomena, behavior, mechanism and situation of heat transfer in the processes of hydronic ice-snow melting on the road. The mathematic model for the numerical simulation was established. The basic formular relationship for the heat transfer was studied comprehensively to establish the theoretic foundation for numerical simulation.
