[ausev] A/C in an EV

[TERRY KING]

I don't have exact figures in my head regarding how much horsepower is used to run an R-134 air conditioning compressor off an ICE, but I think it would surprise us all. I'm thinking at least 10 to15 HP to run one. Another alternative that just popped into my head is those 12 volt coolers that are plugged into the cigarette lighter. I don't remember the principle on which they work, and I haven't ever owned one to see how much capacity they have but they might be adaptable.

While a realize a question of motives might be a bit of a stretch for
this list, I am kind of curious for a brief take on why you do not
plan on using refrigerant.

I live in TX too, and I sure as heck plan on having A/C in my car, but
in my car, the plan is to just use the refrigerant that is already in
the car, and just hook an electric motor to run the compressor. (Even
if I didn't use the refrigerant, I would still have to dispose of it.)
This method is less efficient, but it is cheaper and easier.
