I want to take advantage of the cooler weather and begin the process of installing a new freezer/refrigerator system. I read the discussions about the various condenser units available on the market and made a few phone calls and, based on the information I gathered, I have decided to use the Sea Frost system and VIP based insulated panels.
Regardless of which brand of condenser you installed, I am interested in hearing about where you installed your condenser(s) and why you chose that particular location.
I am looking for a location that 1) provides easy access to condenser, 2) is as quite as possible 3) makes thermal sense and 4) is appropriately close to the cold plates.
Any suggestions?

Lee, I too went with SeaFrost. I installed the condenser under the aft berth in the middle compartment. It is a very quiet unit. I turned the fan unit around (under Cleve’s suggestion) and ran 3″ dryer exhaust ducting through to the port sail locker. There is a louvered panel in the compartment where the condenser is. So, it draws air from the inside of the boat and exhausts it into the sail locker. Not real close to the Ice box but the could not come up with anything better. I thought about under the ice box
in the bildge but thought the sea water vapors might be harmful to the condenser.

Hi Lee,
If you look at my blog (http://thesailinglife.blogspot.com) you'll see where my refrigeration compressor is – under the floorboards inboard of the stove. I made an opening there for access and also so I could install a watermaker.

Lee-
If you have not already done, I suggest both Kollmann’s and Caulder’s books on refrigeration.
We have a 1/2 hp 12volt system driving both a freezer between sink and stove, and a frig in the normal spot. One Dole holding plate in freezer, two in the frig. IMHO, success is all about insulation. Add as much as possible.
We have two of three of your wish list on condenser. It is mounted under the qtr berth, so it is not quiet. Water cooling pump is stb, just aft of the v-drive. System runs 2-3 times at night, which I like to monitor, but this is not for everyone. It is reasonably efficient, and quite powerful.

Lee,
My boat came with an Adler Barbour unit that is serving until I get around to upgrading that whole system, starting with the insulation (or lack thereof). The compressor is located to port of the engine, immediately aft of the aft cabin’s bunk’s aft bulkhead (i.e., in the foremost section of the port cockpit locker).
On my last boat I had a Grunert system powered by a 12v 1/2 HP motor. Because I had a big battery bank and good recharging systems, it served me very well during 6 years of full-time liveaboard cruising. I put an insulated divider panel into the original 9 cu. ft. (?) icebox with a pass-thru hole cut at it’s bottom. Then mounted a single large holding plate in the freezer compartment. That one plate kept foods in the freezer frozen hard indefinitely while the bleed-over chilled the refrigerator portion of the compartment perfectly. One plate, very satisfactory performance.
Here’s a neat cruising trick: When you’re stocking up from a butcher’s shop or fish plant in some civilized port, ask them to put your order in their deep freeze overnight. It’ll bring things down much colder than your boat’s unit could do. Then pick it up the next day, wrap it up in the best insulation stuff you can, and get it into your boat’s freezer as fast as you can. Your cold plate will then maintain it in that deep frozen state. I kept chicken, and on another occasion fish fillets, frozen this way for months.

Sounds like a lot of you have traditional holding plate systems like
me. Have you looked at the Sensi-Stat that I designed? It really cuts
down on the cycling of the compressor since it automatically “tops up”
the holding plates when there is “extra” power from the alternator or
solar panels. Lots of other features too.http://www.scadtech.com/?page=204020Refrigeration+Economizer.htm&selecttab=2

Hey Pete-
Could I use one Sensi-stat to control both my freezer and frig, they have independent t-stats and solinoid valves, or would I need two of them?
Have you heard of a device called a Nanopulser? I had a bad experience with one. Really accelerated corrosion of my battery cable ends, and diminished the capacity of a set of golf cart batteries I was using.
How about a special deal on Sensi-stat for sailors smart enough to own P-424s?

Unfortunately, the Sensi-stat is one unit per controlled space.
SCADtech should only sell to distributors rather than compete with them,
but let me see if there is a distributor willing to run a promo for our
group.The nanopulser and similar are intended to knock the sulfites off the
plates of a battery. I used something like this on our RV years ago and
had no problem, but as you know, the marine electro-galvanic environment
has its peculiarities…The Sensi-Stat works on a few principles such as precise thermostatic
control, varying hysteresis, and detection of charging voltages. The
whole manual is available for your study online.Pete

My compressor is located on the port side just forward and to port of the main salon floor opening.
Its not a great shot, but you can just see it in the top left of this piture taken looken forward under the salon.
