【摘要】：居住区热环境是居住区环境中各种热工因素的综合表现。由太阳辐射、空气温度和空气湿度以及风等要素构成,它与气候因子、建筑布局、水景和植物绿化的分布及生活消耗能源产生的能量等方面有关,是多种因素相互作用的结果。对居住区的热环境进行研究能够获得其规模和结构的发展轨迹。随着人们对生活舒适度,绿色健康和安全性需求的增长,居住区热环境的优劣已是绿色循环发展的必需条件,增强人们关于热环境方面的知识也是实现可持续发展的重要环节。此次研究以寒冷地区代表城市西安的居住区为研究对象,在前人研究的基础上,总结了居住区室外热环境的构成要素,分析了影响因子,从寒冷地区住区建筑热环境角度出发,利用建筑被动式原则,研究营造室外风环境、如何高效利用太阳辐射能量、等改善室外热环境的办法,对居住区进行总体设计,从两栋相邻建筑,到建筑组团布局,再到居住小区规划,由小及大地对室外风环境、室外辐射温度场进行模拟分析并提出设计策略。并以寒冷地区城市冬季气候特点、居民日常行为方式以及室外热舒适评价指标为基础,初步提出居住区室外热环境的主要评价指标,为寒冷地区城市居住区的规划设计提供策略和参考。并采用CFD软件模拟的方式,从两栋相邻建筑、局部建筑组团和城市居住区出发,对室外风环境和室外辐射温度场进行了模拟分析,比较了不同体量、不同朝向、不同组团形式和不同规划布局,由小到大、由单体到整个住区的室外风环境和温度场分布特征,并将两者相结合,得出变量因素与室外热环境之间的相互规律,提出了基本的设计策略和方案,并通过实例分析和优化,为进一步讨论怎么样对居住区的热环境进行改进和优化提出了方法和思路,对增加居民生活的舒适程度和减少建筑所产生的能源消耗等方方面面都有十分重要的参考价值。
[Abstract]:Residential thermal environment is the comprehensive performance of various thermal factors in residential environment.It is composed of solar radiation, air temperature, air humidity and wind. It is related to climatic factors, architectural layout, distribution of waterscape and plant greening and energy generated by daily energy consumption. It is the result of interaction of many factors.The research on thermal environment of residential area can obtain the development track of its scale and structure.With the increase of people's demand for living comfort, green health and safety, the quality of thermal environment in residential area is the necessary condition for the development of green cycle, and it is also an important link to realize sustainable development to strengthen people's knowledge about thermal environment.On the basis of previous studies, the paper summarized the elements of outdoor thermal environment of residential areas, analyzed the influence factors, and proceeded from the perspective of architectural thermal environment of residential areas in cold regions.Based on the passive principle of building, this paper studies how to build the outdoor wind environment, how to utilize solar radiation energy efficiently, and how to improve the outdoor thermal environment. The overall design of residential area is carried out, from two adjacent buildings to the building group layout.Then to the residential district planning, the outdoor wind environment and outdoor radiation temperature field are simulated and analyzed by small and earth, and the design strategy is put forward.Based on the characteristics of winter climate, the daily behavior of residents and the evaluation index of outdoor thermal comfort in cold regions, the main evaluation indexes of outdoor thermal environment of residential areas are put forward preliminarily.Provides the strategy and the reference for the urban residential area planning and design in the cold area.Based on the simulation of two adjacent buildings, local buildings and urban residential areas, the outdoor wind environment and outdoor radiation temperature field are simulated and analyzed by using CFD software, and different body mass and orientation are compared.From small to large, the distribution characteristics of outdoor wind environment and temperature field from single unit to the whole residential area are obtained from different group form and different planning layout, and the mutual rules between variable factors and outdoor thermal environment are obtained by combining the two.This paper puts forward the basic design strategy and scheme, and puts forward the methods and ideas for further discussing how to improve and optimize the thermal environment of residential areas through the analysis and optimization of examples.It has very important reference value for increasing the comfort degree of the residents and reducing the energy consumption caused by the building.
