住宅建筑气候适应性通风调控方法

为得出住宅建筑室内可接受热环境的气候适应性通风调控方法,根据适应性模型理论,以aPMV模型为基础,结合重庆地区的调研结果分析得出住宅建筑室内可接受的温度范围;基于状态空间法对重庆地区住宅建筑常用的通风调控技术进行分析研究,包括不同换气次数和分时段设置通风对室内温度的作用分析,从房间温度整体分布角度提出了重庆地区通风技术的分月调控方法;结合室外温湿度等参数的温湿图,具体分析了通风调控对室外气候参数的调控有效区域,得到各月通风调控方法的气候适应性区域。提出的基于室内热舒适适应性模型的可接受热环境的通风调控策略有利于建筑的热工设计和寻求设备的经济运行方式。

Ventilation regulating methods adapting by climate for residential housing

To study the climatic control strategies of the residential building indoor acceptable thermal environment, firstly, based on adaptive model, integrated indoor activities, clothes and spot investigation on air velocity of residential building, this paper calculates an acceptable temperature range. Secondly, through state-space techniques, common passive regulating technologies in residential building have been simulated, including different ventilation rates and divided-period setting ventilation effect on indoor temperature. Meanwhile, monthly regulating methods for ventilation have been proposed. Thirdly, through ventilation technology, effective regulating zone of outdoor climate parameters have been analyzed, which is combined with hythergraph of outdoor temperature, humidity, solar radiation and air velocity. Taking the characteristics of the human thermal comfort adaptability into consideration, the energy-saving potential of the study results is also analyzed.
