Example 2: a space is to be maintained at 24 C DBT and 50% relative humidity. Heat losses from the space are 66000 W sensible and 16500 W latent. The latent heat transfer is due infiltration of cold, dry air. The outdoor air required is 1700 m³/hr at 2 C DBT and 80% RH. Determine the quantity of air supplied at 49 C DBT, the state of the supply air, the size of the furnace or the heating coil, and the humidifier characteristics.
