混凝土楼板辐射供冷空调系统在亚热带地区的适用性

Applicability of concrete slab radiant cooling air conditioning system to subtropical zone

以广州地区某办公建筑为例,评估了混凝土楼板辐射供冷空调系统的满负荷能效比。计算分析了混凝土楼板辐射供冷的热物理特性、夜间蓄冷损耗以及夜间维持房间正压的冷损耗等,并最终得出混凝土楼板辐射供冷空调系统的综合能耗比。结果表明,混凝土楼板辐射供冷空调系统在亚热带地区的应用不具有明显优势。

Taking an office building in Guangzhou as an example,evaluates the full-load energy efficiency ratio.Analyses the thermal-physical characteristics,calculates the cooling losses in the cooling storage and for maintaining the room positive pressure during the night,and finally obtains the integrated energy efficiency ratio.The results indicate that the concrete slab radiant cooling system does not have a notable advantage to be employed in the subtropical zone.
