剧院座椅下送风不同冷负荷率的最优送风温差分析

摘要

以广州某剧院为例,发现剧院座椅下送风在不同冷负荷率下送风温差存在优化空间.采用CFD模拟软件,通过正交实验的方法对剧院座椅下送风冷负荷率在100%、75%、50%时的不同送风温差进行计算分析.通过对比温度场和速度场,探究剧院座椅下送风不同冷负荷率与送风温差的关系.得到剧院座椅下送风在100%、75%冷负荷率的最优送风温差为3 ℃,在50%冷负荷率的最优送风温差为2 ℃.%Taking a theater in Guangzhou as an example, the under-seat air supply temperature difference can be optimized in theater with different cooling load rates in summer.Using the CFD simulation software,various air supply temperature difference is calculated through orthogonal experiment under the cooling load rates of 100%, 75% and 50% in theater in summer.By comparing the temperature field and velocity field, e the relationship between the different cooling load rates and the temperature difference of under-seat air supply is explored in the theater.The optimal air-supply temperature difference are 3 ℃ in 100% and 75% load rates, and the optimal air-supply temperature difference is 2 ℃ in 50% load rates in summer.
