高层住宅朝向及平面形式对室内泛潮的影响机制研究

Influence Mechanism of Orientation and Plane Form of High-rise Residential Buildings on Internal Surface Dewing of Wall

广东春季2-4月频繁出现“回南天”返潮天气,室内墙体、家具出现泛潮、结露现象,给人们的日常生活带来巨大困扰。区别于以往研究多着眼于设备、构造、材料等方面,本研究侧重验证建筑设计策略对室内泛潮结露的影响特征。从建筑设计常涵盖的朝向、平面形式、公共空间等要素出发,设计模拟实验方案,利用OpenStudio软件进行室内环境模拟,观察建筑布局等相关要素对室内环境的影响规律。模拟结果显示,朝向对室内结露影响显著,西南朝向受到室外高温高湿空气影响,更容易产生结露风险;在T形(塔式)、蝶形(塔式)和通廊式(板式)3种平面形式中,板式布局结露风险最小。根据此结果,从建筑设计的角度提出防泛潮结露的改善策略。

The damp weather in southern China(Huinantian in Chinese) frequently occurs in spring from February to April in Guangdong, along with the dewing phenomenon on indoor walls and furniture, greatly disturbing residents' daily life. Different from previous studies, which mainly focus on equipment, structure and materials, this study tries to verify the influence characteristics of architectural design strategies on indoor condensation. It focuses on the layout of the building, detailing the elements such as orientation, plane form and semi-outdoor space, and utilizes the software of OpenStudio to conduct indoor environment stimulation. The simulation results show that the orientation has a significant effect on indoor condensation, and the southwest orientation rooms are more likely to produce condensation risk due to the influence of outdoor high temperature and humidity. Among the three plane forms of T-shaped(tower), Butterfly-shaped(tower) and Corridor type, the Corridor type residential building has the least risk of condensation. According to the results, the study proposes improvement strategy for anti-dewing from the perspective of architectural design.
