Yeah, another clueless hippie, with a silly political conspiracy tale
when it's obvious that the real reason is that it's not practical or worth
it to use outside air for a fridge. The amount of energy a fridge uses in
total isn't much, what it uses in winter helps heat the living space. Even
if it worked perfectly, the difference would be small. Running
ducts outside would not only be a pain in the neck, but it would require a
more powerful fan, cost a significant amount of money, and introduce it's
own energy losses, eg the ducts would be leaking heat into the living space
in summer, taking it out during winter, any protrusions through the walls
wind up leaking air too, etc.

it's amazing that you can get a split A/C that would easily accomplish
this without ducting

So you want to run refrigeration lines all over a house to install mini split heat pumps in every room? You can get a 5 zone mini split system that works very well with an option for ceiling cassette, wall mount, hidden ducted or universal indoor units that can be mixed and matched connected to the same condensing unit. The systems have all kinds of nice features like individual temperature control for each zone, optional WiFi interface and very quiet operation but there are some things to consider. A line set must be run to each unit, power and thermostat wiring to each unit and a possible penetration of the wall for each unit, more points for possible refrigerant leaks and the complexity of the system. When the cost of all the options is added up, such a multi zone mini split system can be much more expensive than a ducted central HVAC system. There are small duct high velocity systems that are much more affordable than a multi zone mini split system without the complexity. If I had to install an HVAC system in any home, I'd choose the small duct high velocity system. ^_^
