空调制热运行时送风温度的优化分析

Research on optimization of air-conditioned room supply air temperature

针对冬季非采暖区利用空调制热运行时,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,人体极不舒适的现象,利用fluent软件模拟了送风温度分别为30℃,35℃,40℃下,空调房间内温度场的变化情况及三种送风温度不同的组合方案,分析人体活动范围1.8 m以下的温度随时间的变化情况以及热力分层现象,得出最佳的组合送风方式。

When air conditioning and heating runs, common air supply takes a long time to stabilize, and at this time vertical thermal stratifica- tion phenomenon is severe and poor human comfort. In this paper, fluent software to simulate the air temperature was 30 ~C, 35 ~C, 40 ~C, the air-conditioned room temperature changes at different times, primary analysis of the temperature change over time about 1.8 meters below of hu- man activities as well as the phenomenon of thermal stratification. Given the above simulation results, the more reasonable solution about three combinations of supply air temperature are simulated, draw the best combination of air supply.
