内嵌管道式建筑结构可以充分依赖建筑结构本身的蓄热性能以及管内循环流体与管壁面的接触来利用低品位能,以减少对电、燃气等高品位能的依赖。由于该结构的最大优点是低温差传热、蓄热性及其冷热负荷的转移能力,因此传热模型对该结构的优化设计及优化运行极为重要。本文回顾了该结构传热模型的发展并进行了简要分析。在实际应用中,多维模型在与现有建筑能耗仿真软件包在集成时有一定的局限性,而一维模型能够很容易地实现集成。有很多学者研究了该结构的一维热网模型,但如何系统准确地确定模型的阶数及热阻、热容等参数都很少论及。
The built-in pipeline structure can fully rely on the heat storage performance of the building structure itself and the contact of the circulating fluid in the pipe with the wall of the pipe to utilize the low-grade energy to reduce the dependence on high-grade energy such as electricity and gas. Because the biggest advantage of the structure is low temperature difference heat transfer, heat storage and heat transfer capacity, so the heat transfer model of the optimal design and optimal operation of the structure is extremely important. This paper reviews the development of this structural heat transfer model and gives a brief analysis. In practical applications, the multi-dimensional model has some limitations when integrated with the existing building energy simulation software package, and the one-dimensional model can be easily integrated. Many scholars have studied the one-dimensional heat net model of the structure, but how to systematically determine the model order and thermal resistance, heat capacity and other parameters are rarely discussed.
