I'd be quite surprised if it achieved a better delta-T overall, though it could certainly move the reference point to a more favorable location than the inside of a closed van. And don't be totally shocked if it makes the thing stop working entirely: I was quite impressed back in the day to find that adding a boxer fan to pull chunks of air out of that space caused a definite deterioration in performance. Wouldn't surprise me a bit to find that there's a definite delta-T necessary between those two sets of fins in the back. As to the 2.5 amps, that's a 1.5 orders-of-magnitude increase over the intermittent 60 ma of the stock setup and to me is out of the question for off-grid use, not to mention the noise. As originally constituted and with all its faults this fridge would run 2-4 weeks on one charge of propane, without running down the battery. Of course I feel the same way about the Norcold.

Well, I stopped short of suggesting using the water tank as a heat reservoir for my Peltier idea. I submit that in the half-assed spirit of this whole discussion. <g> david -- David Beierl - Providence RI USA -- http://pws.prserv.net/synergy/Vanagon/ '84 Westy "Dutiful Passage," '85 GL "Poor Relation" |
