Air conditioning systems with dual ducts: nnovative approaches for the design of the transport network of the air
We present two methods for sizing the network for the transport of the air, from the air handling unit to the terminal units, for a dual duct system, where air flows in the “cold” duct at a temperature less than the ambient temperature, while air flows in the “hot” duct at a temperature higher than the ambient temperature. The methods, compared to the traditional design criteria, lead to a reduction of channel size and, therefore, of overall network size and cost as well.
