摘要
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.
