so what's the difference between that and an air conditioner
Air conditioners just have freon to cool them, a swamp cooler has a big
wheel/fan thing and needs a water hose hooked up. A swamp cooler pours
water over a spinning fan. The water cools the air blowing through it.
Swamp coolers only work in dry enviroments, but they work really good.
Evaporative coolers. Yeah, sorta palusible, however smelly
yuckky things needing water tipped in. Freon (R12) is not
likely to be something you will see a lot of these days. More
likely R22 for 'fridge or home A/C.
Surprisingly the old gas (LPG) powered 'fridge setup works
well (a hydrogen/amonia setup powered by a flame), not
sure how it would do for A/C.
My central air is still R12. It was retrofitted into an older house
though and the "ducts" are really just the space between rafters for a
lot of the house.
Keep the R12 if you can, R290 is the best bet though (I use it
in my pickup truck A/C). R134a simply doesn't work as a retrofit.
Mind you, charging a car A/C system and house system might
be a little different. Some car A/C systems, and I suspect house
might be a little unsafe changed with R290 (propane) in case
of accident.
Most car A/C systems don't really hold enough quantity
of R290 to be dangerous.
It was checked last year and the r12 was fine, so I'll just hope things
stay that way.
