Improving Fridge Airflow
Last fall I added an additional vent and muffin fan to help cool the
enclosure my 8 cu ft. Tundra marine fridge is in.
I have the fridge out and am trying to decide if I need to change where fan
is, direction etc.
Compressor and condenser are located at lower rear of unit in a cutout
across the back and fan on condenser sucks air from left to right looking at
unit from front. Air goes thru condenser then over compressor and then
electronic unit for compressor.
As luck would have it all vents are on right side of enclosure toward rear;
two near bottom ( lowest one has my added fan ) and one up high.
With unit installed there is about 4 inches of air space on sides and back.
I think some type of cross ventilation across lower back of unit would be
best but that is not possible on my boat.
My question concerns the aux fan. Right now it blows in on the lower vent
and I am wondering if that fights the airflow going in other direction from
consenser fan. Should I reverse it to pull air from lower vent? Our should I
be pulling air with fan on upper vent. Not really sure what is best?
Here are pictures of my enclosure and back of unit:
The cabinet the unit is installed in:

and the back of the unit where compressor and condenser are located:

the fan is mounted on condenser to left and pulls air in as noted by
direction arrow.
Any air flow engineers out there? Should switch aux fan to pull air out
of the bottom vent?

Joe,
It looks to me like you have it about right. You're already
supplementing the natural air movement, your muffin fan will provide air
circulation to remove the heat from the enclosure, the condenser fan
will move the air across the condenser. I think changing it would be
splitting hairs. If anything, maybe wire the fan into the fridge so it
only runs when the fridge cycles. The important thing is that you have a
good setup for removing that reject heat. Your fridge should be thankful
to have such a responsible owner.

Stephen wouldn't send this question, so I will.
Kitchen --galley --question? What to do with gunky stuff, like liquid
drained off canned goods, grease in pans, etc? Seems not right to put it
down the head or into sink and thus to bottom of boat or overboard. The
question is where to put simi yucky stuff. Please advise.

Best place is in a 'Yucky Stuff' container that can de emptied/discarded
onshore, etc.

It is warranted air-tight and guaranteed for life. It is presently on sale
for $63.99. Accessories include gimble and rail mounts as well as vinegar
and bleach auto-injector tanks. The ideal galley accessory and gift. A
vacuum insulated model will be available in the Spring.

Gunky, yucky food stuff?? <grin> Canned foods are usually stored in their
own juices or plain water.
But if the liquid from the so called food stuff is gunky or yucky why would
you even consider eating the food source? <VBG>
Seriously though; disposal of unwanted food stuff does pose a problem on
board. Water from canned peas, corn, etc. can safely be put overboard except
in harbors, marinas, and other congested places like canals which lack good
water flow.
Fatty residues can be frozen to a hard lump and then dumped in the open sea,
but not inshore ir inland waters. This will then slowly be consumed by
sealife and or bacteria. Nor do I think dumping a collection of containers
of animal fats in dumpsters ashore is a good idea since this is an
attractive food substance to scavengers. This is what attracts rats, mice
and other rodents to marina dumpsters. Wanna pick up a hitch hiker and give
em a ride; or maybe even free room and board?
As a related subject how do people feel about garburators installed in the
galley sink.
This seems like an invitation to attract the unwanted attention of water
quality protection cops and the eventual legislation mandating grey water
retention everywhere, as we now have to do with black water.
I can't imagine a worse situation than a grey water tank sludged up with the
effluvient of a garburator or having the cozy anchorage waters befouled with
a lot of garburators dumping lots of left over dinners into the clean
waters.
Is this an idea whose time should never have come?

I keep an old plastic mayo jar to pour cooking grease into. It works well,
since the polymers they use are resistant to oils and greases. It's actually
just as illegal to discharge cooking oils, animal fats, etc. into the water
as it is engine oil. http://www.epa.gov/oilspill/vegoil.htm.
Other stuff like milk, water from vege cans, etc. just goes down the sink
and overboard. Don't put ANY of this stuff down the toilet unless you've
eaten it first. I usually throw food scraps overboard, figuring something
will eat it.
