摘　　要：对夏季工况5.5 m和8.2 m送风口高度及3种不同送风量下室内温度场和速度场等进行试验研究分析。试验结果表明:送风口高度增大时,分层高度增大导致空调冷负荷增加。在相同送风量下,送风口高度对室内工作区内的平均温度影响较大;送风口高度越高室内风速分布越均匀。Experimental research and analysis on indoor temperature field and velocity field are conducted under 5.5 m and 8.2 m air supply outlet height and three different volumes of air supply of summer conditions.The test results show that：when the air supply outlet height increases,the increased stratification height causes cooling load increase.Under the same volume of air supply,air outlet height has great influences on the indoor average temperature at working area.With the increase of the air supply outlet height,the indoor flow field distribution gets uniform.
