Abstract An innovative new translucent honeycomb solar collector and thermal energy storage module has been designed. The honeycomb module contains two different kinds of channels, namely empty ones and those that are filled with a P hase C hange M aterial (PCM). The latter are sealed at the front and back side and, therefore, form chambers. Solar radiation enters the empty channels and is transmitted forward into them. The absorbed energy fraction at the side walls of these empty chambers leads to a melting of the PCM in their neighboring filled chambers, where then thermal energy is stored as latent heat. A heat transfer fluid, usually air, crosses the empty channels by forced convection and additionally charges or discharges the storage modules. Such elements are ideal to equip “intelligent” building facades in passive houses or then to form thermal storage elements in decentralized air-conditioning systems by integration into the facade of e.g. an office building. This first article presents the innovative solar system and gives new results on simplified two-dimensional temporal-spatial physical modeling, numerical simulation of charging and discharging modes and of a combined mode for a typical practice case. The content of a second planned article on system optimization and full system performance, including the description of thermal behavior of system/building combinations is roughly sketched in the section ‘Conclusions and Outlook’.

用于建筑立面的半透明蜂窝太阳能集热器和蓄热模块

摘要 设计了一种创新的新型半透明蜂窝太阳能集热器和热能存储模块。蜂窝模块包含两种不同类型的通道，即空通道和填充有 P hase Change 材料 (PCM) 的通道。后者在正面和背面密封，因此形成腔室。太阳辐射进入空的通道并向前传输到它们中。在这些空室的侧壁吸收的能量部分导致相邻的填充室中的 PCM 熔化，然后热能作为潜热储存。传热流体，通常是空气，通过强制对流穿过空的通道，并额外地为存储模块充电或放电。这些元件非常适合在被动式房屋中装备“智能”建筑立面，或者通过集成到办公楼等立面中，在分散式空调系统中形成蓄热元件。第一篇文章介绍了创新的太阳系，并在简化的二维时空物理建模、充放电模式的数值模拟以及典型实践案例的组合模式方面给出了新的结果。关于系统优化和完整系统性能的第二篇计划文章的内容，包括对系统/建筑组合的热行为的描述，在“结论和展望”部分粗略地概述。第一篇文章介绍了创新的太阳系，并在简化的二维时空物理建模、充放电模式的数值模拟以及典型实践案例的组合模式方面给出了新的结果。关于系统优化和完整系统性能的第二篇计划文章的内容，包括对系统/建筑组合的热行为的描述，在“结论和展望”部分粗略地概述。第一篇文章介绍了创新的太阳系，并在简化的二维时空物理建模、充放电模式的数值模拟以及典型实践案例的组合模式方面给出了新的结果。关于系统优化和完整系统性能的第二篇计划文章的内容，包括对系统/建筑组合的热行为的描述，在“结论和展望”部分粗略地概述。
