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.The objective of this paper is to improve the indoor temperature imbalance caused by the atrium heating and air conditioning system in public buildings in winter,in order to meet the human comfort and improve the economy. The air distribution of the university library atrium in winter was studied. The experimental results were compared with the CFD simulation,and the feasibility was analyzed by using the solar wall technology. Through the air temperature distribution simulation of the library atrium,the vertical temperature of the atrium reaches about 5 ℃. And the current temperature in the atrium cannot reach the design temperature. Using the solar wall fresh airsystem ＋ traditional air conditioning heating coupling can solve the problem of the lowaverage temperature in the atrium,and can ensure the supply of indoor fresh air. From the measured data and CFD simulation of the atrium,using the solar wall reconstruction measures,it is helpful to improve and optimize the heating design scheme.
