A space has a sensible heating load of 60,000 W. The space is to be maintained at 21°C DB while the outdoor air is at 1°C DB and 20% RH. On coil air at 15°C is heated, humidified at the rate of 8 g/s, and supplied to the space at 31°C DB and 25% RH. Determine: a. The total amount of air supplied to the space; b. The amount of outdoor air supplied to the space; C. The relative humidity of the space. 3 Plot the process on a Psychrometric chart.
