I'm wondering if anyone can give my idea a quick sanity check...
I have a giant icebox
on my 424 (48" W x 18" D x 29" H), and it's insulated "reasonably well" for a 1983 boat
(A 5 lb block of ice can last the better part of a week.) Currently it has an engine
driven holding plate _AND_ a 110V AC holding plate, both seafrost, both probably 15+ years of age (they are converted R-12 units).
I'm never on shore power
, and the shore unit draws about 20 amps @ 12Vdc to run through the inverter
, which burns through my battery
pretty fast (i have an 800 AH bank, so i can run it, but it really sucks the power out...)
driven unit doesn't work
great, I charged it again last year, and by the end of the year I really couldn't get it to be very cold, so i think there's a leak somewhere.
I'd like to rip the whole darn thing out and replace with a new, properly insulated fridge with separate freezer
. However this is a big job and almost definitely means replacing the entire kitchen countertops as well, which is more $$$ than i'd really like to spend this year.
As a temporary solution to last this year, I was thinking of taking both units out, and putting in a supercoldmachine with the really large evaporator (like a VD-152)
100 Series Evaporating Unit
This would give me some refrigeration
, draw say 5-7 amps while it ran. The insulation
isn't super, but i'm guessing it will do as well as the holding plate, giving me about 3-4 hours of runtime for every hour i could run the old unit.
With the big evaporator, I could put things in it to freeze them, make ice, and say keep the fridge at 40 degrees over the summer months in NY (ok for meat for a day or two, and i can leave ketchup and other non-delicate stuff and beer
over the week while i'm gone.)
I have 2 windmills (DF400's) and am going to put some solar
on this year as well.
Next year, I'll make a new box, chop the old one up and remove it, and have a new counter laid down. I'd just have to have the coolant
evacuated from the unit, and could then take it out, and reinstall after the new box goes in & recharge, correct? I might put a second unit for the freezer
, but haven't decided yet for then...
Does this seem reasonable or am i crazy and should just either wait till next year and use ice, or bite the bullet and do all the extra work
Basically is installing, then taking it out and putting it back in the new box worth it or more headache than it's worth? Curious as to what people might think!
I've read the kollman docs, so i know the right answer in the long run is proper insulation
, but wondering if a stopgap measure might be worth it for the summer...
