EFFECT OF EXHAUST LAYOUT ON THE INDOOR THERMAL COMFORT UNDER HARSH WEATHER CONDITIONS

The inlet and outlet size, number location have a significant influence on the thermal environment indoor air distribution for temperature velocity. In this work, numerical experimental studies were performed to examine influences of distribution, location, movement indoor. Also, separation amount extracted has been investigated in study. To provide comfortable occupants, important factors such as sensation draft rate should be evaluated carefully. Therefore, paper occupant’s used main evaluation index. investigation, three cases study tested. work was under Iraqi weather conditions which are hot dry summer. finding showed that environments significantly influenced by opening locations exhaust. Also it found satisfied human comfort obtained when exhaust diffuser installed relatively far away from supply diffuser. addition, best results separate two exhausts opening. This will give supplied ability distribute inside room perfectly. order prevent short circuit, not located at wall front
