摘　　要：针对大空间下送中回气流组织室内热环境,以室内空气为研究对象,通过在垂直方向上分层建立能量平衡方程与质量平衡方程,建立多节点温度求解模型,并利用大空间缩尺模型稳态环境实验予以验证,通过4个工况验证结果可知,各空气温度的理论计算值与实验值的最大绝对误差不超过3%,平均误差为1.4%.Focusing on the study of indoor thermal environment under the air distribution of low supply and middle return in large spaces,an energy balance equation and mass balance equation were built to analyze each module in order to get the air temperature in multi-node.Experimental verifications for the calculation results of four working conditions were carried out by using the scale model of a large space laboratory.As shown by the results,the absolute value of maximum error between theoretical and experimental values of air temperature in respective areas is 3%,and the average error is 1.4%.
