The air temperature difference inside a duct refers to the variation in temperature between the air entering the duct and the air exiting the duct. This temperature difference is influenced by factors such as the heat gained or lost through the duct walls, the efficiency of the HVAC system, and any insulation present in the ductwork. Monitoring and optimizing this temperature difference is important for ensuring effective heating or cooling of the space.
