Terminal units. Air terminal unit
Air terminal units represent the supply air terminals (diffusers, grilles, nozzles, etc.) into which the ducts of the all-air systems flow.
In the program, these must be connected to an air conditioning system (such as an air handling unit), depending on their type.
Air supply outlet
This terminal unit represents an air supply terminal connected to a constant air flow system, or a centralised ventilation system, depending on the option chosen.
