A building has a total heating load f 200,000 Btu/hr. The sensible heat factor for the space is 0.8. The space is to be maintained at 72°F and 40% RH. Outdoor air at 40°F, 20% RH in the amount of 1000 CFM is required. Air is supplied to the space at 100°F. Find a) the conditions and amount of air supplied to the space b) the amount of water at 50°F required by the humidifier section c) the capacity of the heating equipment needed d) the temperature rise of the air through the heating unit.
