Conventional multizone units continuously maintain a cold deck temperature capable of satisfying the maximum cooling demand of the warmest zone and a hot deck temperature capable of satisfying the maximum heating demand of the coolest zone. This approach ignores the actual, continually changing heating and cooling requirements of the building, resulting in unnecessary energy consumption. This video presents an improved control strategy that automatically adjusts to the building’s real-time requirements. In documented applications, this logic has reduced HVAC energy consumption by more than 50% while maintaining occupant comfort.
