Josh,
My AC was working fine when I started my conversion, and I was able to
unbolt the compressor before I removed the engine. That way
everything stays sealed. I figured that would be better than having it
emptied and recharged.
I plan on using either a separate DC motor to direct drive the
compressor, or use an AC motor with VFD. Whichever one is less
expensive is what I will end up going with. From what I have heard on
this list you will need about 2 HP at about 1500-2500 RPM. Direct
drive is better than using a belt drive as it will minimize belt
losses and wear on the bearings. However, It all depends upon what
fits.
You can us the 12V signal that was going to the compressor clutch to
run a motor starter to turn on the motor, so it only runs when you
need it.
