15.6 An air conditioned space is maintained at 25°C DBT and 50% RH. The outside conditions are 40°C DB and 25°C WB. The space has a sensible heat gain of 24.5 kW. Conditioned air is supplied to the space as saturated air at 10°C. The equipment consists of an air washer. The air entering the air washer comprises 25% outside air, the remainder being recirculated room air. Calculate: (i) Volume flow rate of air supplied to space. (ii) Latent heat gain of space. (iii) Cooling load of air washer.
