摘　　要：通过实验研究了地板送风系统的室内环境特性。研究了三种不同送风风量下室内不同位置的温度分布情况。实验结果表明,送风口位置和送风量的大小都会影响室内垂直温度分布。当送风口风量增大时,送风动量也随之增大,垂直温度分布梯度变缓。室内温度分层高度随室内送风量的增大而增加。通过两组不同送风量实验对比,结果得出,送风口流速相同时,其送风射流所能达到的最大高度相近。In this paper,the indoor environment characteristics of floor air supply system are studied by experiments.The temperature distribution of different locations in the room under three different supply air volumes was studied.The experimental results show that the location of air supply outlet and the volume of air supply affect the vertical temperature distribution in the room.When the air volume of the air supply outlet increases,the air supply momentum also increases,and the vertical temperature distribution gradient slows down.The stratified height of indoor temperature increases with the increase of indoor air supply volume.Through the comparison of two groups of different air supply volume experiments,the results show that the maximum height of the air supply jet is similar when the flow velocity is the same.
