Abstract
The flow air from a hot air duct and a cold air duct into a zone of a building is controlled in based upon performing a thermal energy balance calculation for the zone. That calculation produces a heat transfer setpoint from which a hot air flow setpoint and a cold air flow setpoint are derived. The hot and cold air flow setpoints respectively control the flow of air through the hot and cold air ducts.
