DC Fridge ?

Friend of mine took an old "dorm" fridge and glued 3/4" styrofoam all around the outside. It looked like hell but he says it cut his power use dramatically. If the unit is going to be in a cabinet, the styrofoam wouldn't show anyway.
 
Not sure about glueing styrofoam to the outside as the outside metal is used as the heat radiator.
 
Nah this one had coils on the back... the styrofoam DID help.
 
Insulation helps as long as the heat exchanger (coils) are exposed. Mine has a small low current DC fan that blows air across the coils.

I've seen several installations where the fridge is built-in with no ventilation... Not exactly efficient.
the DC fan should help a lot.
