Yup... but I doubt you could get insurance if they knew you were installing a propane powered refrigerator...

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Smile Improving energy efficiency of refridgerators on board.

Hello,

As a future investment i'm thinking of getting a compressor refridgerator wich has an automatic feature that freezes icepacks at full power for ~3 hours and the shuts off - cooling the contents for zero power draw - until a sensor discovers renewed need to freeze the packs. (Indel Isotherm ASU).
Quite nifty , i must say.


I currently still use a thermoelectric cooler on my boat.
I greatly improved the cooling by mounting a stronger 12 volt(PC fan) and insulating the inside with 3cm thick 'finnfoam' , thats a special hot compressed styrofoam that doesn' crumble when cut.

Now it cools up to 35 °c under the surrounting temp. (used to only manage 15°c). the volume though now is down to 20 liters(from 30).

Its also important to ensure that there is cool air circulating around the unit.
12v Deck vents .

I am planing to install a thermostat or timer - And see if that brings down the 4 amp per hour draw.

Erik.
