Abstract :

<p>&nbsp;The motive of this type research is to learning the appearances of indoor thermal background on the room of Indian&nbsp;</p> <div>Building. Experimental measurements were accompanied in aassessmentroomby means of the Floor level Air&nbsp;</div> <div>Distribution (FLAD) schemes. This research examines supply air stream velocity and the temperature distribution in&nbsp;</div> <div>different locations such as Inlet, roof, floor, left wall, and right wall of the room buildingat the indoor environment. The experimental results of&nbsp;</div> <div>supply air flow velocity and temperature distributiondisplay that the supply air flow velocity for a single supply vent and for first case is 0.20 m/s&nbsp;</div> <div>for the V1 option, and for second case is 0.25 m/s for the V2 option; and for third case is 0.30 m/s for the V3 option. Theresults also show that the&nbsp;</div> <div>indoor vertical temperature distribution is influenced by the distance between the measuring location and the supply vent position. When the&nbsp;</div> <div>measuring position is nearby to the sourceopening, the temperature distribution contour is inclinedthroughthe supply habituated airflow at&nbsp;</div> <div>inlet is 293k, Roof is 300k, Floor is 295k, and Left wall is 305k, Right wall is 305k. While the distance from the sourceopening is greater than 0.20&nbsp;</div> <div>m, the temperature distribution come to besomewhatdependable. The temperature distributionoutline isn&rsquo;tinclinedmeaningfullyvia the return&nbsp;</div> <div>openingsite. The supply air stream rate and air flow velocity can variation the temperature distribution</div>
