摘要
指出了在空调制热运行时,从开机到室内到达舒适的温度需要较长的时间,而且稳定后垂直方向热力分层现象比较严重,人体极不舒适。针对以上这种现象,利用Fluent软件模拟了送风温度分别为22℃、26℃、30℃、35℃、40℃下,空调房间内温度场的变化情况,并分析了人体活动范围1.8m以下的温度随时间的变化情况以及热力分层现象。
When the heat mode of air conditioner runs ,it takes a long time from starting to reaching comfortable indoor temperature ,and after the stabilization of the temperature ,the vertical thermal stratification is severe and people will feel uncomfortable . Aiming to these problems , this article uses fluent software to simulate the temperature changes in the air -conditioned room w hen the air temperature is respectively 22℃ ,26℃ ,30 ℃ ,35 ℃and 40 ℃ ,and analyzes the temperature changes of people′s moving range under 1 .8 meters over time as well as the phenomenon of thermal stratification .
