1- Calculate the cooling load for an orange store room, 3 x 9 x 2.5 m, maintained at 0 °C db and 80 % R.H. and holding 3000 kg of oranges at 4°C. Heat of orange respiration is 0.0074 W/kg. Outside air conditions 27 °C db and 50% R.H. assume overall coefficient of heat transfer through the room 0.47 W/m2 °C, number of air changes per day 10, and machine works 20 hours per day and factor of safety is 10%.
