Research on Indoor Thermal Environment of Variable Air Flow Rate in Under-floor Air Distribution System Room
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.
