[T3] Happy New Year

An interesting alternative for lower-powered classic vehicles is to have an
ice-box (literally) and re-circulate the cabin air though that!
The electric vehicle forum at
http://www.diyelectriccar.com/forums/showthread.php?t=5527 suggests that.
They also confirm the 600W rating needed for electric compressors, but you
have obviously done that research already.
We don't have a serious problem over here for excessive heat, though I do
appreciate the air-con on our nearly-new Golf (Rabbit) on occasion. I
recall 110F in the Central Valley in California when over for the Oregon
Invasion, and certainly needed it there for comfort. However, the vent-wing
windows on a Type 3 are better than many modern cars to catch a breeze.
Maybe we need a chute into the airbox so we can shovel ice in there, but
check your drains first!

It would be an interesting project, but keep in mind that the generator
output is limited to 30 A total. So you probably can't count on diverting
more than 10 A to an electric A/C compressor.
The car needs the rest to run the FI fuel pump, the FI brain & injectors,
and the ignition. If you need wipers and/or headlights things get worse.
One thing I should do someday would be to measure normal current consumption
at cruising speed with various loads turned on.

The electric compressors they use on hybrids I think pulls about 50 A. Using
the stock generator would be out of the question with this unless I could
put an extra marine battery on it and charge between trips. Doubt I would
get much millage out of that. If I went this way I would have to come up
with an alternator set up putting out at least 80 A. The first concern I
would have with this is how well it would fit or seal up around where the
generator goes so there is not so much hot engine compartment air being
sucked up around it. The other would be how much of a strain would be on a
stock FI engine. Like I said this is kind of last on the list so who know I
may just drive it between early October and late April.
