某博物馆中庭及相邻区域热环境数值模拟

摘要

有透明围护结构的中庭具有“温室效应”和上部空间热量堆积的特点，特别是竖直方向上有明显的温度梯度。以某博物馆的中庭及与其相通的走廊为研究对象，利用 CFD 软件模拟了夏季3种工况、冬季2种工况下的热环境，并对夏季3种工况进行了能耗分析。建议在夏季，将中庭及与其相连的走廊作为一个整体进行空调设计，上层空调机组承担较多的负荷，下层空调机组承担较少的负荷；在冬季，中庭地面设置地板辐射供暖。%The atrium with the transparent envelope has the characteristics of greenhouse effect and heat accumulation in the upper space,especially obvious temperature gradient in vertical direction.Taking the atrium and adjacent cloister of a museum as an example,simulates the thermal environment under three conditions in summer and two conditions in winter using CFD software, and analyses the energy consumption under summer conditions.Suggests that in summer,taking the atrium and adjacent cloister as a whole,the upper air conditioning units bear more load,while the lower air conditioning units bear less load;in winter,adopts floor radiant heating in the atrium.
