Why can't the ACs run off propane too?

After reading the con's of generators and the pro's of solar panels, it seems that most of us would prefer not using a generator. However, as some folks pointed out, summer camping in many areas is unbearable without air-conditioning - which seems to be the main reason for the generators. Since the refrigerator can run on 120 volt, 12 volt and propane - why can't they design an AC unit that works the same way? Refrigeration cycles are the same, whether AC or refer, and the air mover can work with 12 or 120 volts, so where is the problem.

I can only imagine the problem is how large it would have to be but if someone knows, I'd be interested in finding out.

Thanks,

Mike

  • Fridge in rv has no air movement, I don't think anyone would want an air conditioner with no fans. It would take a couple days to cool off a room.
  • How are you going to power the fans? Propane is a heating source. Refrigeration systems like an AC unit use compressed gas which when heated boils. That source of heat is the warm air you are trying to cool.
  • Technically an absorption AC could be made. In fact most large commercial buildings have an absorption "chiller" outside that makes cold water to feed their massive AC requirements.
    These systems are so large they are only done on commercial buildings. You don't even find houses with this. Putting on in an RV would be virtually impossible. Not to mention extremely expensive, and heavy.
