摘　　要：提出了一种大空间下送风分层空调环境下的同步求解模型,用于预测室内空气垂直温度分布和内壁面温度分布以及下送风环境下的空调冷负荷;进行了大空间建筑下送风环境下的夏季热环境实验,实测室内空气垂直温度分布和内壁面温度分布以及夏季冷负荷,并验证对比了实验值和模型计算值,结果表明温度数据吻合良好,冷负荷的相对误差小于10%。A simultaneously solving model is presented under the low sidewall air supply system of thermal stratification environment in large space building.The model is used to predict indoor vertical air temperature and inner surface temperature,as well as the cooling load.Through the summer experiment in a large space building,the indoor air vertical temperature,inner surface temperature and cooling load are tested,the calculated results of simultaneously solving model are compared with the test data,and the results show that the temperature data agreed well,the relative error of cooling load is less than 10%.
