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. 3-Effective room sensible heat factor (ERSHF

The air in a theatre room must be 22 °C and the relative humidity 55%. The outdoor temperature is 30 °C and relative humidity 50%. There are 900 seats in the room and 25 m³/h of fresh air is reserved for each seat. Every attendant releases a heat load (sensible + latent) of 100 W and a moisture load of 80 g/h. The sum of heat loads from other than human sources is 20 kW. What must the supply air state be in order to maintain the indoor conditions mentioned above?
Pls. Answer thank you! An auditorium is designed to seat 4500 people. The ventilation rate is 1.62×107 ft³/hr of outside air. The outside temperature is 0°F dry bulb, and outside pressure is 14.6 psia. Air leaves the auditotium at 70°F dry bulb. There is no recirculation. The furnace has a capacity of 1,250,000 Btu/hr. The temperature at which the air should enter the auditorium is most nearly?
6) A room’s sensible space load is from occupants and infiltration, but excluding intentional ventilation, is 3.2 kW. A total of 600 L/s of outside air is required. What is most nearly the room sensible heat ratio?
