Okay so I know this is a dumb idea but the more I think of it, the more potential it has.
Here is the background:
I have a 1979 Pearson 365 Sloop
. Great Vessel. I have a standard Ocean Breeze A/C which does great when running from the dock
. On the hook, I know if I were to try to run it off a Honda
it would be just a bit more than the genset could handle (probably have to have a 3k which is just too big and also $1900) , plus the whole noise
, gas on a diesel boat
issue, and other issues.
I live / sail mainly in Florida
. 4 months of the year it is HOT. Like 90+ heat index in the evening! A little breeze (with LOTS of humidity) brings down actual temps to low 80's but the Heat Index stays up about 90 at night in the boat
So recently I replaced the original AB Fridge system. I mean at 36 years old, I couldn't complain about the service
life. Got a good price
($850) for an Isotherm
2501 - installation
was easy - cools GREAT! Draws 1-5 amps depending on how much I open the cold box.
SO that is what got me thinking. What if I bought another Iso 2501, installed in the bottom of my starboard locker in the forward compartment, built a water
proof box on the next shelf up for the evaporator, added a blower to blow over the evaporator and out into the forward v berth, and only ran it right before I went to bed
, until the humidity and temp dropped a bit. Maybe pulling 7 amps for 5 hours of cooling
in that fwd compartment only. Say 35 amps for the evening of relaxing sleep in the v berth. As this is an air cooled unit - Hot Air cold be directed into head
which has roof hatch
. Many little issues to be thought out but I think you get my drift.
Assumption is 250AH House Bank (4 6v T105's in 12v config)
Recharge via 2 x 250W solar panels
Total average battery
usage on hook or underway is 85 amp per day
so on the days we used this hybrid a/c kludge we would use 135 amps per day.
So Much Better than a gas generator
and all the accompanying issues.
So how bout it friends? Is this a ridiculous idea?
Look forward to your thoughts, ideas, etc
