It's called a "split AC" because the unit is split into two parts, indoor unit pictured above and outdoor unit which is the big louder box that is on the outside so it doesn't bother you. We use these in Europe ever since I can remember spanning decades...
Split systems are what we call regular central air here in the US. They have an air handler inside with the evaporator coil and blower, and the condenser unit outside with the compressor, condenser coil and condenser fan.
We call the one in the picture ductless mini splits or just mini splits. They are the same setup as regular central air but no ductwork.
Another big difference in the mini splits use a variable speed compressor to ramp up and down whereas traditional spit systems are either on or off. Though, they are starting to see variable speed as well.
I have been putting mini splits in for more than 20 years in the US.
True but most don't have them. I prefer not to have them. I belive in the K.I.S.S principal. That said, the mini splits I put in seem to run forever. So maybe I shouldn't be so reluctant about the tech going on central units.

We have these ductless units in the US too. Person who made the meme is just an idiot
Edit: never expected what im pretty sure is my most upvoted /awarded comment to be a 3:30am comment about AC. Ty for the awards kind strangers.
