I have read that they can require something like 10 hp to spin at "hiway"
speeds - 2000 rpm?
Sounds like an interesting project. It would require some sort of
electrical supply to engage the clutch, at least on the compressors I have
seen. It seems like the electric clutches draw quite a bit of current also,
just by watching the volt meters in the cars and trucks I have had.
Maybe a 14-18 horse kohler or briggs would have a big enough charging system
to keep a auto battery going for a while anyway.
Good luck, and keep us posted.
That was what I was thinking too. Maybe our Irish guy wasn't that far off.
Maybe a motorcycle engine. I figured I would spin up an alternator too to run
the evaporator. I doubt the one on a bike would be enough.
If you folks haven't figured it out I am going for a hurricane A/C plan without
having to buy a pad mount generator. I already have a propane fridge and a gas
I do heating and AC work for a living, and I would not even bother with what
you want to do, even if all the parts were free! Trust me, a genny will be
much easier, cheaper in the long run!
You must have a ton of free time on your hands!
12-14 HP engine,
Oversized fuel tank,
Then somebody that is licensed to charge it up! (good luck with this part!),
then on top of all this you still would have a electric condensing unit for
the rest of the time, and somehow interconect the two.
Do you live in a city, one that requires permits? If the city inspector saw
this in our city, it would not fly. No UL label? No install in our city!
Seems pretty crazy to me to build something you will use a week or two out
of every 5-10 years!
What you are suggesting has been done for years on refrigerated cargo
trailers and some busses. I never saw it but a friend once told me of a
church cooled by a unit powered by a Ford flathead auto engine.
Check out the power unit of a "reefer" or refrigerated trailer, (like
those used to haul produce) That will give you a good idea of the size of
the components you will need.
