How do multi-zone ductless mini splits achieve multiple circuits, heads?
My google and search skills are not turning up anything about how these
things work in regards to multiple heads. I'm thinking they don't
have a compressor for each head/circuit, but I have no idea how they
achieve that? Maybe they have one motor and multiple compressing
pumps? Scroll of some sort or what? I'm simply very curious as I had
one today. (This house had three heads and two outside units.
These things were 30 years old. Sanyo. Two of them are working just
fine still. The one is low on refrigerant. A fast leak, evidently as it was
cooling fine just a week ago. But I don't care about these units--so if
anybody asks me about pressures and ambient and airflow (!), I SWEAR
I'm going to slit my wrists. :) )
My questions and interests are just about DMS in general.
