针对变风量地板送风系统，建立了室内空气热力分层的数值模型。用Airpak对一办公室变风量地板送风系统进行了实例模拟，分析讨论了地板送风口的送风量、风口数目以及风口出风角度等参数对室内空气热力分层的影响。结果表明，适当的送风量与送风形式能达到较好的热力分层及换气效率。
針對變風量地闆送風繫統，建立瞭室內空氣熱力分層的數值模型。用Airpak對一辦公室變風量地闆送風繫統進行瞭實例模擬，分析討論瞭地闆送風口的送風量、風口數目以及風口齣風角度等參數對室內空氣熱力分層的影響。結果錶明，適噹的送風量與送風形式能達到較好的熱力分層及換氣效率。

A numerical simulation model of indoor air thermal stratification is established for Variable Air Volume Underfloor Air Distribution(VAV-UFAD) system. Based on Airpak software, an example is simulated for the VAV-UFAD system of an office, thus make an analysis of the influence of outlet airflow, distribution numbers and the angle of outlet on indoor air thermal stratification. The results show that the ap-propriate parameters of outlet air could achieve better air thermal stratification and air exchange efficiency.
