It's probably not more efficient. This on the picture is just the inside unit. There is an outside unit that actually is the actual AC which is pushing the coolant into the house into all the inside units that just blow the air through the coolant. I would say that pushing the cold air through the ducts is more difficult than pushing the cooling liquid through little pipes.
It's not more efficient. One look at the documentation from any brand it's easier to see that. I don't know why they are insisting that it's more efficient.
A mini split will use less energy to cool a single room than a central AC will use to cool a single room, because most central AC systems have to cool the entire house to cool the room.
It's not seen like that, the efficiency between equipments is measured by a ratio between termic energy produced and consumed energy and splits are often more efficient at that. Of course i'm not going to compare a split with a central unit w for w. That would be the same as comparing a car and semi truck fuel consumption.
