摘要
以上海某展览温室为研究对象,利用数值模拟法对上海夏季4种典型工况下(高太阳辐射天气、低太阳辐射天气、阴雨天气、有风天气)的温室室内热环境进行模拟,并依据模拟结果分析室内热环境的形成原因。结果表明:采用遮阳和自然通风均可使夏季温室的室内温度降低;除阴雨天气外(关闭顶部通风窗),在其余工况下均可采用上述2种措施使温室的室内温度达到设计要求;室外空气流动也可使室内温度降低,且会影响室内温度的分布情况。模拟结果可为采用大面积透明围护结构建筑的夏季室内热环境的预测及改良提供参考。
Using an exhibition greenhouse in Shanghai as the research subject,the numerical simulation method is used to simulate the greenhouse indoor thermal environment under four typical working conditions(high solar radiation weather,low solar radiation weather,rainy weather and windy weather)in summer in Shanghai,and the formation causes of indoor thermal environment are analyzed according to the simulation results.The results show that:both shading and natural ventilation can reduce the indoor temperature of the greenhouse in summer;In addition to rainy weather(closing the top ventilation window),the above two measures can be used to ensure that the indoor greenhouse temperature of meet the design requirements in other working conditions.Outdoor air flow can also reduce indoor temperature and affect the distribution of indoor temperature.The simulation results can provide a reference for the prediction and improvement of indoor thermal environment in summer with large area transparent envelope buildings.
