摘　　要：本文对空调工况下空气柱(上送下回)送风的气流组织,温度场,速度场,空气龄进行了仿真模拟。结果表明。制冷工况下,送风温度为18℃、20℃,风速为3 m/s、空气柱高度为2~2.5 m时,单柱舒适区大小为21 m×21 m×1.7 m,区域ADPI值均大于80%,平均PMV值为-0.34,平均PDD值为8.67%。制热工况下(上送下回),送风温度为26℃、28℃、30℃,风速为2~4 m/s、空气柱高度为2~2.5 m时,区域ADPI值均大于90%,平均PMV值为-0.47,平均PDD为10.2%。单柱区域内制冷工况热舒适性优于制热工况舒适性。In this paper, the airflow organization, temperature field, velocity field and air age of the air column(upward and lower) air supply under air conditioning conditions are simulated. The results show that under the cooling condition,when the supply air temperature is 18 ℃, 20 ℃, the wind speed is 3 m/s, and the air column height is 2~2.5 m, the single-column comfort zone is 21 m×21 m×1.7 m. The regional ADPI values were all greater than 80%, and the average PMV value was-0.34, and the average PDD value was 8.67%. Under heating conditions(up and down), the air supply temperature is 26 ℃, 28 ℃, 30 ℃, and the wind speed is 2~4 m/s, and the air column height is 2~2.5 m, and the regional ADPI value is greater than 90%, and the average PMV value was-0.47 and the average PDD was 10.2%. The thermal comfort of the cooling condition in the single column area is better than the heating condition comfort.
