Refrigerator Insulation

My 2010 Jeanneau 42i has an air cooled compressor under the galley sink, that is directly adjacent to the refrigerator it's supposed to keep cool. Not sure who thought this was going to be a good idea, but looking for ways to improve the efficiency of the refer. Looking at lining the refer with this: Cryogel® – Pacor, Inc.

Does anyone have any experience with this or another product that might improve the performance of my refer?

This stuff is great we use it to do our doors , expensive to do a whole box with it .

We get ours on ebay.

Re: Refrigerator Insulation

Venting the cabinet containing the compressor may help, something like a computer fan that kicks in every time the compressor does ?

Re: Refrigerator Insulation

+1 for Aerogel, Cryogel.
We did our box several years ago, also made a portable "freezer" for meat and ice cream by trading a pair of these out of our freezer compartment each day:

and a separate "refrigerator" for veggies using a pair of these:

https://www.amazon.com/Arctic-Ice-Al...tic+ice+tundra

The refrigerator runs a lot more because we have more than doubled the effective size of our box but with plenty of solar, who cares?

My wife is an accomplished seamstress and made a couple of cryogel insulated zippered bags which live under the forward berth. They fit the space perfectly and were made to fit the largest size freezer brick/refrigerator brick.
Our freezer compartment JUST FITS one freezer and one refrigerator brick.
Each day we swap the pairs.

Re: Refrigerator Insulation

Yes, a little computer fan should extract the heat and could be wired right to the unit to shut on and off. Also, possible to put a vent in the cabinet wall right where the refrig fan blows?

Re: Refrigerator Insulation

One thing to remember if you decide to add another fan . The Danfoss controllers are limited to .5 of an amp , so if you add a fan and connect it to the controller, the combine amperage must not exceed .5 of an amp . If it does, the controller will trigger an error and the compressor will not start .
To over come this you could use a relay and control the fans that way . You could also install a snap temperature switch on the top of the compressor like the one below and have it switch a fan on when it reaches certain temperature to remove warm air from the cabinet space .

You will have to find one that has the right "turn on" temperature.

Regards John.
