Ducted Mini Split Trunk/Branch Question
I am having trouble visualizing how to use a slim duct mini split with a trunk and 3 branches (each branch going to a room). What is the name of the fitting that would come off the supply on the slim duct unit? Or is the fitting that comes off the indoor unit typically just fabricated to fit each install? I am hoping I can drive air into 3 bedrooms and then use each door's passive return to bring air back to a hallway/entry and back up to the unit in the ceiling.
Thanks in advance.
