Q2. Compute the total heat gain load from all the sources into a residence space
of 25*20*10 height,if the space is located at the top floor of an air
conditioned commercial building. The residence space has one exposed wall
facing South.
-Wall facing S, (25* 10); 12" brick on the outside, (the overall heat
transmission value(U) is 0.25 Btu/hr.ft². "F).
-Roof; 4 concrete with 2" insulation, Uroof 0.35 Btu/hr.ft.F
- Windows facing S ;No.(2), (3*3),single regular plate,double-hung
metal windows,weather-stripped; unlocked ,shaded with cream inside
roller shade,fully drawn.
-Occupants: (5) persons; moderately -active office work.
-Lightening :2.5 kW
-Equipments: No. (1) ; domestic gas oven.
-Outside conditions:T-85 F (db) &T-70 F (wb), DR-25 F, Vwind=10
