| 摘 要： | 基于Airpak软件,选用室内零方程湍流模型对一夏季空调办公室内热环境进行了三维数值模拟,得到室内气流组织下的流场、温度场分布.采用PMV-PPD与空气龄指标对室内人员热舒适性及空气品质进行了评价,并通过测试室内温度、风速参数,验证了数值模拟结果的准确性.研究表明:对于分体式空调器房间,气流组织分布与空调器的安装位置、室内设备的摆设以及室内人员的分布有关,不同的气流组织将形成不同速度场和温度场.室内温度场分布在水平方向比较均匀,在垂直方向产生明显的温度分层;室内零方程湍流模型能准确快速模拟空调通风房间气流组织分布,PMV-PPD与空气龄指标能对人体热舒适及空气品质进行数值预测与评价,为房间空调器送风温度、速度参数的合理设定提供参考依据;热环境数值模拟对空调系统的气流组织设计、运行调节具有重要的指导意义.
