I know on some models, for example some Chevy Vans, you can get dual zone (front and rear) independent AC control. How does this work? Are there actually multiple evaporators? Do there need to be multiple condensers, etc?
How do dual AC systems work?

Exactly, they have separate everything except that they share the same freon and compressor. Essentially freon is flowing through both systems however if the heat is chosen for the rear instead of AC then the mode door in the rear switches over in the rear HVAC box to direct air over the heater core instead of the evaporator and the same goes for the front HVAC.

Just realized that you said condensers too. They share one condenser.

slightly less complicated. You only have 1 condenser/evaporator in a dual zone setup.The difference is in the HVAC "case". It's the monstrosity behind the dash that does the work. Basically there are motors that control the requested temperature and adjust flaps and doors inside the "case" accordingly.
