Q3/ An auditorium is to be maintained at a temperature of 26°C dry bulb and 50% relative humidity. Air is to be supplied at a temperature not lower than 15°C dry bulb. The sensible heat gain is 110 kW and the latent heat gain is 37.5 kW. Take ventilating air as 25% by weight of the air from the room and is at 35°C dry bulb and 60% relative humidity. Determine the refrigeration capacity in tons of refrigeration (TR).
