A method for converting an air conditioning system, for cooling an environment, having respective hot and cold air supply ducts and a dual duct terminal box wherein the hot and cold air is mixed to achieve a desired temperature for delivery to the environment, to a more efficient system by replacing the hot deck of the hot air duct with a cold deck similar to that of the cold air duct and replacing the dual duct box connected to both ducts with one or more types of terminal boxes capable of varying the volume of delivered cooled air to control room temperature. The variable volume terminal boxes may have either limited or unlimited volume variation capability and those with limited variation may be provided with means for heating the residual constant volume furnished at the lower limit of volume variation. The invention also provides for increasing the cooling ability of a system through the use of higher capacity terminal boxes.
A method for converting a dual duct, dual temperature constant volume air conditioning system for increased efficiency, said system having first and second parallel ducts, means for propelling air through said ducts, means for heating the air flowing through said first duct, means for cooling the air flowing through said second duct, and terminal air delivery means connected to said first and second ducts for mixing the air in said first and second ducts in suitable proportions to deliver air to an environment which is to be maintained at a preselected temperature comprising:
A method for converting a dual duct, dual temperature constant volume air conditioning system for increased cooling capacity, said system having a fan with a capacity for propelling air through first and second ducts, means for heating the air in said first duct, means for cooling the air in said second duct, and means for mixing the air in said first duct with the air in said second duct in suitable proportions to deliver to a controlled environment air of suitable temperature, comprising:
