The outdoor conditions are 40 0C dry bulb temperature and 27 0C wet bulb temperature. The various loads in the auditorium are as follows: sensible and latent heat loads per person, 80 W and 50 W respectively; lights and fans, 15000 W; sensible heat gain through glass, walls, ceiling, 15000 W. The air infiltration is 20 m3 /min and fresh air supply is 100 m3 /min. two-third recirculated room air and one-third of fresh air are mixed before entering the cooling coil. The by-pass factor of the coil is 0.1 find 1-Apparatus dew point. 2-The grand total heat load. 3-Effective room sensible heat factor (ERSHF

2- A conference room for seating 100 persons is to be maintained at 22 0C dry
bulb temperature and 60% relative humidity. The outdoor conditions are 40 0C dry
bulb temperature and 27 0C wet bulb temperature. The various loads in the
auditorium are as follows: sensible and latent heat loads per person, 80 W and 50
W respectively; lights and fans, 15000 W; sensible heat gain through glass, walls,
ceiling, 15000 W. The air infiltration is 20 m3
/min and fresh air supply is 100
m3
/min. two-third recirculated room air and one-third of fresh air are mixed before
entering the cooling coil. The by-pass factor of the coil is 0.1 find
1-Apparatus dew point.
2-The grand total heat load.
