The ventilation system for the classroom provides 15 m3/h per person, and there are 16 occupants in the classroom. The outdoor air is at 5C and 80% relative humidity and indoor air is at 22C and 50% RH. Each person releases 70W of sensible energy and 0.04kg/h of water vapor by sweating and breathing. Also, the light is on, and total electric energy consumed by light is 0.5kW. a) Calculate sensible and latent loads (assume that heat gain is equal to heat loads) of the room only
