【摘要】：寒地有着严酷的气候特征，严寒、室内外温差大、多降雪、多强风等气候特殊性，使得寒地建筑室内环境舒适度面临较大挑战。而天窗的使用，为寒地建筑提供了充足的采光、改善了室内通风条件、提高了室内热环境舒适度，为室内微环境的改善发挥了重要促进作用。本文从办公建筑的中庭天窗设计作为研究出发点，通过对天窗设计元素的探索，研究对室内微环境的影响，以寻求适应于寒地气候，改善室内微气候环境的天窗设计。由于天窗设计主要对室内光环境、风环境有着较大影响，故而本文的研究主要针对室内自然采光、自然通风展开。本文主要使用数字化模拟技术，对天窗设计问题展开研究。在熟练掌握光模拟软件Autodesk-Ecotect、风模拟软件Ansys-Airpak使用方法的基础上，在保持其他设计参数不变的情况下，通过设置不同组天窗设计变量，分别探索了该变量对室内采光、通风的影响，最终得出了适应于寒地气候，利于办公建筑室内微气候环境优化的天窗优化变量。本文主要内容依照问题提出、问题分析、问题解决三个步骤依次展开。首先，在分析室内采光、通风原理的基础上，确定了天窗设计要素中的平面位置、分布形态、洞口尺寸、剖面形态、剖面尺寸等为室内采光、通风的影响变量。其次根据Autodesk-Ecotect软件模拟所需，探索了寒地采光边界条件，调整了采光分析模型，进行了室内采光模拟实验；并对不同变量下的模拟结果进行了充分的对比分析，并得出了适于寒地办公建筑光环境优化的最优解；在此基础上，提出了寒地办公建筑天窗采光优化的设计策略。再次，根据Ansys-Airpak软件特点，探索了寒地通风边界条件，设置了通风分析模型，展开了室内通风模拟实验；并在此基础上，对不同天窗变量下的通风模拟结果通过充分的对比分析，得出了适应于寒地办公建筑室内风环境优化的最优解；在此基础上，提出了寒地办公建筑天窗通风优化的设计策略。本文通过对室内光环境与风环境的模拟，探讨了寒地办公建筑天窗的设计，以期能够有效改善室内微气候环境，最终实现满足室内舒适度的要求。本论文由黑龙江省科技计划项目：东北寒地绿色建筑关键技术研究支持。项目（课题）编号：GC11T110
[Abstract]:Cold region has harsh climate characteristics, cold, large indoor and outdoor temperature difference, more snow, more strong wind and other climatic particularity, make the indoor environment comfortable in cold area facing a great challenge. And the use of skylight. It provides sufficient lighting for cold buildings, improves indoor ventilation conditions, improves indoor thermal environment comfort, and plays an important role in promoting indoor micro-environment improvement. This article from the office building atrium skylight design as the starting point, through the exploration of skylight design elements, to study the impact on the indoor microenvironment, in order to seek to adapt to the cold climate. Because the skylight design mainly affects the indoor light environment and the wind environment, the research in this paper is mainly aimed at indoor natural lighting. Natural ventilation development. This paper mainly uses the digital simulation technology to study the skylight design problem. Master the optical simulation software Autodesk-Ecotect skillfully. On the basis of the use of wind simulation software Ansys-Airpak and keeping other design parameters unchanged, this paper explores the indoor lighting by setting different sets of skylight design variables. Finally, the optimal variables of the skylight suitable for the cold climate and the indoor microclimate environment optimization of office buildings are obtained. The main content of this paper is divided into three steps: problem analysis and problem solving. Firstly, based on the analysis of indoor lighting and ventilation principle, the plane position of skylight design elements is determined. Distribution form, hole size, profile shape, section size are the influence variables of indoor lighting and ventilation. Secondly, according to the Autodesk-Ecotect software simulation needs. In this paper, the boundary conditions of lighting in cold region are explored, the model of lighting analysis is adjusted, and the indoor lighting simulation experiment is carried out. The simulation results under different variables are compared and analyzed, and the optimal solution suitable for the light environment optimization of office buildings in cold area is obtained. On this basis, the design strategy of lighting optimization of skylight in cold office building is put forward. Thirdly, according to the characteristics of Ansys-Airpak software, the boundary conditions of ventilation in cold area are explored. The ventilation analysis model is set up and the indoor ventilation simulation experiment is carried out. On this basis, the simulation results of ventilation under different skylight variables are compared and analyzed, and the optimal solution suitable for indoor wind environment optimization of office buildings in cold area is obtained. On this basis, the optimization design strategy of skylight ventilation for office buildings in cold area is put forward. Based on the simulation of indoor light environment and wind environment, this paper discusses the design of skylight in cold office buildings in order to effectively improve the indoor microclimate environment and finally meet the requirements of indoor comfort.
