I have an Adler Barbour "Cold Machine" refrigerator on my sailboat. If I
measure the Ah consumed at say 25 deg C ambient can I extrapolate to
what it will draw at 30 deg C? I don't want to wait till summer 2008 to
predict this Ah drain.
If the heat gained through the ice-box walls is proportional to the
outside/inside temperature difference should I assume that a similar
relation exists between the compressor temperature difference and duty
cycle? This then would give something close to a square law relation
between temperature difference and duty cycle.
Any refrig' experts?

WAECO quote a ratio of 1.6 for the running time at 20degC to the running
time at 32degC

Thanks Alec, I couldn't find that info on the Adler-Barbour website.
