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. ^_^

I once stayed in a "hotel" that had the room heated with a refrigeration
unit.
The fan blew the heat from the condenser into the room.
Utterly useless. I did a moan got a fan heater and was asked not to leave it
on all night. Yeah sure.
