【摘要】：目的对公共建筑中庭冬季供暖空调系统导致的室内温度不均现状进行改造,以满足人体舒适性,提高经济性.方法对沈阳地区某高校图书馆中庭冬季采用传统空调供暖的气流组织分布情况进行研究,对实测结果与CFD模拟结果进行对比,分析是否符合《公共建筑节能设计标准》,提出采用太阳墙技术并分析其可行性.结果通过对图书馆中庭进行温度场模拟发现,中庭的垂直温差达到5℃左右,当前中庭内温度并不能达到设计温度.采用太阳墙新风系统+传统空调采暖耦合作用能很好地解决中庭内平均温度偏低的问题,且可以保证室内新风量的供给.结论从中庭实测数据及CFD模拟出发,使用太阳墙改造措施,有助于改进和优化采暖设计方案.
[Abstract]:Objective to improve the indoor temperature imbalance caused by atrium heating and air conditioning system in public buildings in order to satisfy human comfort and improve economy. Methods the distribution of air flow in the atrium of a university library in Shenyang in winter using traditional air conditioning heating was studied. The measured results were compared with the results of CFD simulation, and the results were analyzed whether it was in accordance with the Standard for Energy Saving Design of Public buildings. The solar wall technology is proposed and its feasibility is analyzed. Results by simulating the temperature field of the library atrium, it was found that the vertical temperature difference of the atrium was about 5 鈩，
