An air-conditioned room is to be maintained at 18oC, percentage saturation 40%. The fabric heat gains are 3000 W and there are a maximum of 20 people in the room at any time. Neglecting all other heat gains or losses calculate the required volume flow rate of air to be supplied to the room and its percentage saturation when the air supply temperature is 10oC. (Sensible heat gains per person = 100 W; latent heat gains per person = 30W; barometric pressure = 1.01325 bar)
