Re: Modern AC Compressor in a 6-Volt Car

I don't know where this electric bypass solenoid stuff came from.

On the original Packard system the only compressor control was to take the belt off.

When the heat load in the system falls the pressure in the system also falls. There was a high pressure relief valve and that was it. In cold weather the TXV will close and the low side run a vacuum while the high side condenses into liquid. You can't compress a vacuum so not much happens.

So for a car in Texas there is no reason to screw around with batteries in the trunk, and cables, and all that non-sense unless you want to dazzle everybody at a CCCA cocktail party.

I can see Jim hooting that up in my mind right now. It must have been hilarious.
