空调送风温度对室内舒适性的影响分析

摘要

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 .%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。
