被动式太阳房阳光间通风口优化设计
|
摘要
针对农村建筑节能改造设计中不同结构的附加式阳光间节能效果差异较大的情况,改良阳光间建筑结构形式并分析其温度场和气流组织分布情况,确定了最优建造方案。以河北省石家庄市某农宅为基础,对其阳光间进行开孔设计。在阳光间内侧墙面上开设不同半径和数量的通风口,设计12种不同的模型。结合Fluent模拟数据,对不同变量进行对比分析,研究不同半径和数量的通风口对室内热环境的影响,确定运行效果最优模型,对运行效果最优和效果最差的两种模型进行对比分析,进行通风口优化设计。结果显示,通风口半径为0.15 m,设置3个进风口2个出风口时,室内温度最高。研究成果可以为附加式阳光间的设计提供参考,可用于改进农宅建筑形式,提升农宅附加式阳光间的节能效益。
In the design of rural building energy-saving renovation, the additional sunlight energy-saving effects of different structures are quite different. It is necessary to improve the architectural form of the sunlight and analyze its temperature field and airflow distribution to determine the optimal construction plan. The article is based on a farmhouse in Shijiazhuang City, Hebei Province, which has vents for the additional sunlight. With opening vents of different radii and number on the inner wall of the additional sunlight, 12 different models are designed. Combining different variables with fluent simulation data, the effects of vents of different radii and number on indoor thermal environment are studied, and the model with the best opera-tional results is determined. The optimal design of vents is carried out by comparing and analyzing the two models with the best running effect and the worst effect, and the reason is analyzed for the optimal design of vents. The results show that when the vent radius is 0.15 m and there are three air inlets and two air outlets, the indoor temperature is the highest. The research results can provide reference for the design scheme of the additional sunlight room, improve the building form of the farm house, and improve the energy-saving efficiency of the additional sunlight in the farm house.
