A 3,500-seat auditorium is to be air-conditioned using window units 10 kW nominal value. Assume that a person at rest will dissipate heat at a rate of approximately 360 kJ/h. There are 200 lamps in the auditorium, each rated at 250 W. The rate of heat transfer to the auditorium through the walls and windows is estimated to be equal to 150,000 kJ/h. If the auditorium air goes to maintain at a constant temperature of 200°C, determine the number of air conditioning units of required window. Answer: 45 units.
