【摘要】：皖江地区位于长江下游,是长江流域经济带的重要组成部分,随着当地的经济发展,皖江地区新建村镇住宅的形式已经发生变化,开始出现集中式的多层住宅,住宅能耗的也逐渐增加。由于经济和技术水平的限制,村镇建筑节能中更多地采用被动式节能设计,自然通风作为一项既能改善室内热环境,并且不产生能耗的被动式设计,具有很大的应用潜力。然而通过调研发现,与传统民居相比,在新建的村镇住宅中自然通风设计已经逐渐消失,在住宅设计中有一些弊端不利于自然通风。与城市相比,村镇地区良好的自然环境更适宜去利用自然通风,需要更多关注。本文中通过调研、测试以及软件模拟等方法,对村镇住宅的自然通风系统展开了研究。全文共分为六章,第一章主要概述了研究背景、意义与目的,并对国内外相关领域的研究现状进行了概述。第二章首先总结了热舒适评价标准,重点阐述了适用于自然通风建筑的适应性模型,以及风速对于建筑室内热舒适的影响；介绍了国内外的自然通风技术的原理和效果,包括安徽传统民居的自然通风设计策略。第三章中对皖江地区村镇住宅进行了调研和测试。经过调研,将皖江地区村镇住宅归纳为三种住宅形式,分别为独栋住宅、联排住宅和集中式住宅。采集当地气象数据,逐时记录住宅室内气温和相对湿度,并进行了现场风速测试,最后对这些数据进行了分析。第四章中基于适应性模型,提出了适用于当地村镇住宅自然通风系统的量化评价方法,并利用CFD软件,对村镇住宅自然通风系统中的建筑布局、平面设计、外窗形式以及气窗设计等影响因素进行了模拟分析。第五章中,根据提出了皖江地区村镇住宅自然通风系统设计的七项原则,并对三种住宅案例进行了自然通风系统优化设计,分析了住宅的气流组织方法。第六章中全面地概括了本文的研究内容和成果,并对研究工作中存在的问题和局限性以及以后的研究方向进行了简要阐述。
[Abstract]:The Anhui River region is located in the lower reaches of the Yangtze River and is an important part of the economic belt of the Yangtze River Basin. With the development of the local economy, the form of newly built villages and towns houses in the area of Anhui River has changed, and centralized multi-storey housing has begun to appear. Residential energy consumption is also gradually increasing. Because of the limitation of economic and technical level, passive energy saving design is more widely used in town and village buildings. As a passive design which can improve indoor thermal environment and does not produce energy consumption, natural ventilation has great application potential. However, compared with the traditional residential buildings, the natural ventilation design has gradually disappeared in the newly built villages and towns, and some disadvantages are not conducive to natural ventilation in the residential design. Compared with the city, the good natural environment in the village and town area is more suitable to use natural ventilation and needs more attention. In this paper, the natural ventilation system of village residence is studied by means of investigation, test and software simulation. This paper is divided into six chapters. The first chapter summarizes the background, significance and purpose of the research, and summarizes the current situation of research in related fields at home and abroad. In the second chapter, the evaluation criteria of thermal comfort are summarized, and the adaptive model suitable for natural ventilation building and the influence of wind speed on indoor thermal comfort are expounded, and the principle and effect of natural ventilation technology at home and abroad are introduced. Including Anhui traditional residential natural ventilation design strategy. The third chapter investigates and tests the villages and towns residence in Wanjiang area. Through investigation and investigation, the village and town residence in Wanjiang area is divided into three kinds of residential forms, which are single family residence, joint house and centralized residence. The local meteorological data were collected, the indoor air temperature and relative humidity were recorded time by hour, and the field wind speed was measured. Finally, the data were analyzed. In the fourth chapter, based on the adaptive model, a quantitative evaluation method is put forward for the natural ventilation system of the local village residence, and the layout and plane design of the natural ventilation system of the village house are designed by using the CFD software. The influence factors such as the form of outer window and the design of air window are simulated and analyzed. In the fifth chapter, according to the seven principles of design of natural ventilation system of village and town residence in Wanjiang area, the optimization design of natural ventilation system is carried out for three kinds of housing cases, and the method of air flow organization of residence is analyzed. In the sixth chapter, the research contents and achievements of this paper are summarized, and the problems and limitations in the research work and the research direction in the future are briefly described.
