基于既有公共建筑室内热环境改善的气流组织优化研究

Research on air distribution optimization based on improvement of indoor thermal environment of existing public buildings

以影响既有公共建筑室内热环境状态的气流组织为研究对象,针对不同季节既有公共建筑室内热环境状况,采用实测与模拟相结合的方法,对比分析了不同气流组织形式下室内热环境的特征,分析了不同气流组织形式和参数对热环境温度场和风速场的作用,明确了不同季节影响热环境状态气流组织的主要因素。基于作用分析,从气流组织设计层面对比了改善室内热环境的关键因素,提出了优化策略。

Taking the air distribution that affects the indoor thermal environment of existing public buildings as the research object,aiming at the indoor thermal environment of existing public buildings in different seasons,this article compares and analyses the characteristics of indoor thermal environment under different air distribution forms with the method of combining actual measurement and simulation.The effects of different air distribution forms and parameters on the temperature field and wind velocity field of the thermal environment are analysed,and the main factors affecting the air distribution of the thermal environment in different seasons are clarified.Based on the analysis of the effects,the key factors for improving the indoor thermal environment are compared from the air distribution design level,and the optimization strategies are proposed.
