摘　　要：针对地板送风的特点,综合考虑温差射流和重力的影响,得出计算格栅式地板送风口射流的速度和温度分布的公式。与实验结果的对比表明,公式计算结果可以满足工程计算要求。在不同送风参数和送风口尺寸条件下,计算并分析各参数对格栅式地板送风口射流的影响规律。Based on the characteristics of the UFAD,comprehensively considered the influence of the temperature difference and the gravity,establishes the formulas for the velocity and temperature distributions of grid-type supply-air autlet air-jet.Compared to the experimental results,the results of the formulas are applicable for engineering calculation.Introduces the parameters influencing on the air-jet of the grid-type supply-air outlet under the different air supply and size of supply-air outlet.
