摘　　要：在实验小室内进行冬季工况送回风的实验,对比了1.6m和1.8 m不同高度的送风口下的下回下排、下回上排、上回下排和上回上排四种排回风形式的小室内温度分布的特性,得到结论:在公共建筑内排回风形式选择下回下排、下回上排和上回上排形式,测点在垂直方向上温度梯度不均匀,房间不同高度的水平面上各区域的温度值相差较大,不易得到均匀的温度分布场;下回上排比较合适,垂直方向上各测点的温度曲线变化趋势一致能够得到较均匀的温度场。The experiment in a cell about supply air in winter was carried, contrasting the temperature distribution of four forms including blower-exhaust and blower-return, upper-exhaust and blower-return, blower-exhaust and upper-return, upper-exhaust and upper-return between the different heights of 1.6 m and 1.8 m. There is a conclusion that it is more appropriate to chose the form of upper-exhaust and blower-return because of it＇s uniform temperature field. Temperature gradient of measuring points by blower-exhaust and blower-return, blower-exhaust and upper-return, upper-exhaust and upper-return is uneven, and areas of different height have huge temperature difference and it is difficult to form a uniform temperature field.
