摘  要:阴雨天及高温高湿季节,地下车库温度仍为较低状态,常出现结露现象。针对车库结露现象,以邯郸某车库为例,对实际监测数据进行分析,使用仿真软件对贴壁射流加热车库壁面温度效果进行模拟,对比不同贴壁送风工况下车库壁面的温度变化,得出避免车库壁面出现结露的较优送风工况,为车库结露问题的防治提供参考。模拟结果表明:选用2.0m×0.3m条缝型风口尺寸贴附效果较好,对比于送风速度4m/s,当送风温度为6m/s时,墙面最低温度为23.5℃,高于最不利露点温度2℃,达到防结露目的。末端采用多风道送风,当两侧风道送风偏移角度由0°增大到60°时,送风轴心的壁面温度下降0.2-0.3℃,温度降低较小,而风口交界处壁面温度上升1-3℃,使交界处壁温在25-28℃变化,对于壁面风口轴心温度过剩而交界处温度不足具有较好改善作用。In rainy days and high temperature and humidity seasons,the temperature of the underground garage is still low,and dew often occurs.Targeting the garage condensation phenomenon.Taking a garage in Handan as an example,through analyzing the actual monitoring data,simulation software was used to simulate and analyze the temperature effect of the wall surface heated by the wall-attached jet,and the temperature changes of the garage wall under different wall-attached air supply conditions were compared,and the optimal air supply conditions were obtained to avoid dew formation on the garage wall,providing reference for the prevention and control of the garage dew formation problem.The simulation results show that the size of 2.0×0.3m^(2) slot tuyere has good effect.Compared with the air supply speed of 4m/s,when the air supply temperature is 6m/s,the lowest temperature of the wall is 23.5℃,which is 2℃ higher than the most unfavorable dew point temperature to prevent dew formation.When the air supply Angle increases from 0° to 60°,the temperature of the air supply axis decreases by 0.2-0.3℃,and the temperature of the wall surface at the junction of the tuyere increases by 1-3℃,so that the wall temperature at the junction changes between 25-28℃,which has a better effect on the excess temperature of the shaft center of the wall tuyere and the insufficient temperature at the junction.
