    Flow to a Fan coil unit

    In a job we are doing, we are putting Fan coil units with supply air blowing into the back, so the supply duct doesnt actually connect to the unit.

    How would you go about calculating the flow in this case if the duct doesnt connect to anything?

    Model an extrusion in the fan coil that sticks out the back. Make it invisible and put a duct connector on it. So it is actually connected and can be linked to a flow in the unit, but just looks like it isnt on drawings.

    or.. take an endcap, change its category to air terminal, change the connector from fitting to preset. Make return and supply versions and use them to give flows to open duct ends.

      Yes was thinking of doing the end cap method, just one question why preset? and not calculated?

        If you want the FCU to tell the system how much air it needs, use preset. Set a flow by fan coil type or by individual room.
        If the flow is already defined from top down (By an AHU, VAV box or something) use calculated.
