I found nice compression grommets for your watertight compartments.

Tell us more about the application.

No, they have this marvelous new technology called electricity!

I am putting in a 12V freezer, that way it can run when it needs to
regardless of what our power config (shore power, underway, anchored,

genset running, etc).


Even a 12 V electric compressor can be noisy. With just a few feet of
plumbing you can have a more proffessional set up and better access to
your compressor in the engine room.

Not sure yet whether I'm going to get a custom welded stainless steel

box & insulate it in place, or mold a fiberglass box myself and put
in a
cold plate. Either way I'm thinking of putting in those expensive
vacuum
insulation panels.

Right now I'm leaning towards cabin ambient air cooled, with exhaust
to
the outside. This is how our fridge is set up.


Id go with the stainless steel. Make it a double walled 6" thick min.
and inject expandable foam in it. Will last forever.

Front or top access?

A refrigerator is a heat pump.

It is rather stupid to put the compressor in a hot engine room because
it decreases the efficiency of the heat pump when the hot side of the pump
is in a hot environment.

It's far better to put the compressor in as cool and well-ventilated space as
can be found on the boat within the limits of the copper tubing to the evaporator,
of course.

I hope this helps.

Am I understanding this right? A Peltier chip that can achieve a 130 +
degree delta-T?? What's the catch, only the USAF can afford them???

It's worth a phone call to find out, anyway. Plugging in these numbers
results in a very nice installation... efficient and compact.

Thanks Bob C!

You may be able to get them as free samples. Coleman and others make entire
refrigerators out of these things.

Keep cool,

Amen!

I've always felt engine-driven refrigeration is superior, but our boat came
with a 12V Adler-Barber. Bottom line: our friends with engine-driven
compressors have had numerous problems, while we have had absolutely none.
The 12V compressor is quiet to the point of only hearing it when it runs at
night and I'm wide awake listening to the carp roll and thump against the
boat. Our friends have ****ed off others in quiet anchorages with their
nightly fridge recharge (engine run).

Strictly anecdotal, and not an endorsement of DC refrigeration.

Depends on what you call "noisy." We just put in a new 12V fridge. You
can hear it running if you stand next to it... you can hear the
thermostat click... and that's about it.


... With just a few feet of

your compressor in the engine room.


If you're talking about engine driven, it's too cumbersome and only
works when underway. And the compressor will run at all kinds of RPM
depending on everything except what the refrigeration system needs.
Really inefficient, plus you have refrigerant lines draped all over the
engine room. I'm not seriously considering engine driven refrigeration.

It would make more sense to have a 120VAC 3-phase diesel genset driving
a compressor, that would be smaller, quieter, more efficient, more
flexible with regard to layout, and you could tie in more efficient
3-phase appliances. Hard to find off-the-shelf stuff though, and it'd be
a lot more expensive (unless you could scrounge most of the parts).



Id go with the stainless steel. Make it a double walled 6" thick min.
and inject expandable foam in it. Will last forever.

We don't have the cubic for that thick insulation, especially not with a
double walled SS box. And pour-in foam has a poor R value, about 3 or 4
IIRC. A poor match economically. If I was going to spend that kind of
money I'd get the whole thing put under a vacuum, maybe put in a little
dedicated vacuum maintainer pump. It'd be one big Thermos!



Front or top access?


Top. It's going under the dinette settee. With 4" insulation we can get
a smidge over 4 cu ft, although it has to be irregularly shaped.

Any reason why? I feel that it's superior if one assumes 1960s level of
technology.

Hmm, it sure sounded like one. Thanks a lot for the info... I have
already spec'd & priced a system using Adler-Barbour components and that
is certainly a strong contender.

Thank you again-
