革新的な冷暖房システム導入によるゼロカーボン建築の実現ポテンシャルに関する研究

首先，对不同辐射系统进行了实验研究。在札幌市的一栋nZEB办公楼中进行了应用辐射顶板和地下水热泵系统的实地研究。热性能和舒适性测量的结果被分析并发表在杂志上。其次，基于实验结果的设计优化方法的开发也在进行中。利用CFD数值模拟技术，对弧形分段结构的辐射顶板进行了参数分析。研究结果也进行了总结，并发表在《华尔街日报》上。此外，还建立了灰箱模型，并用前人的实验结果进行了验证。该模型将用于辐射系统的预测和优化。

Firstly, the experiments on different radiant systems were carried out smoothly. A field study was conducted in a nZEB office building applying the radiant ceiling panel and groundwater heat pump system in Sapporo. The results of thermal performance and comfort measurements were analyzed and published in the Journal. Secondly, the development of design optimization methods based on the experimental results was also in progress. A parametric analysis was carried out by using CFD simulation on the radiant ceiling panel with curved and segmented structure. The results were also summarized and published in the Journal. Besides, a grey-box model was developed and validated with former experimental results. This model will be used for the prediction and optimization of the radiant systems.
