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?
