Spethmann, D H

In an air conditioning system having both a hot deck for heating air and a cold deck for cooling air, both decks being supplied by a supply duct, a control system is disclosed for minimizing the total cost of heating the air in the hot deck and cooling the air in the cold deck by measuring the amount of heating done in the hot deck and deriving the heating cost therefrom, measuring the amount of cooling done in the cold deck and deriving the cooling cost therefrom, and controlling the temperature of the air in the supply duct until the heating cost equals the cooling cost to thereby minimize the total heating and cooling costs.
