Fraunhofer ISE Optimizes Climate Control Systems with Simulation

能源 建筑工程

Eric Laurenz, Hannes Fugmann, Fraunhofer ISE, Germany

吸附式气候控制系统主要依靠废热、天然气及废气进行驱动,因此它能减少建筑物制冷与制热所消耗的电能。尽管吸附式制冷机、热泵和储热单元已实现商用,但要进行更大规模的应用,还需进一步提升该技术的效率和紧凑性,并降低生产成本。

位于德国弗莱堡的弗劳恩霍夫太阳能系统研究所(Fraunhofer Institute for Solar Energy Systems,简称 ISE)借助数值仿真和实验更深层次地理解并设计了吸附系统中的换能器,其中包括使用网状结构来增加传热表面的面积。借助 COMSOL Multiphysics® 软件,研究团队捕捉到了吸附和解吸过程的动力学特征,以及释放到建筑物中的热量。他们的工作包括模拟水蒸气和热流过多孔结构(如吸附剂)的过程,以及等温流体流动和固体中的热传导问题,这些研究帮助他们开发出了更好的换热器结构。
