Climate control, Fan blower amps usage and Time to turn off, A/C Heat 3rd Battery etc
1) For those Wagon passengers vans with the rear A/C option: with the key in, turned at first position, engine not running ("key off"?) can the rear blower fans push fresh outside air? At the blower speed of my choosing? Does it stop after a while (perhaps 30 min) or will it run until the battery dies? If it stops after a preset time, can you change a fuse or something so that it doesnt stop (perhaps until the current drops below 12.2V or 10.5V or something.
2) What is the total electrical consumption of those blower fans , at the various blowing speeds?
3) With the Dual heavy-duty battery option, how many amp x hour do you get from your batterie, is it 78?
4) with the gas heavy duty 210A alternator how long does it take to recharge the dual heavy duty batteries,about 20min? (78/210 x 60min)
5) With the engine not running can you get A/C and heat in those rear blower fans? If yes, until the batterie dies or it stops after a preset time? what's the amp consumption like for each A/C and heat?
6) How do you get humidity out? when its cool outside maybe turning on the van's heating? and when it's hot outside, can you turn on both heat and A/C at the same time?
7) Regarding connecting a separate interior 12V/110V A/C in the summer, heater in the winter, and sometimes a dehumidifier, have you guys tried that? Do you know good products that can be bought off-the-shelf (that goes inside the van not the ones you fix on the roof)? windows intake / vent/exhaust hose through the 2nd-row driver-side flip-open glass? I'm guessing 300W (25A) should be enough, but on a 78 amp hour battery that would give a discharge rate of 1/3, ie 3 hours discharge time (possibly even less because of Peukert's law), would that be too much for the batterie chemistry on the long run? I suppose adding 2 other 78amp hour batteries in parrallel to the van's batterie would make the discharge time better.
The 12V socket "customer connection point on the outboard side of the driver seat pedestal" is what, a 15A maximum? Which means for more than 180W I would need a direct connection to the batterie(s)?
