   That isn't correct. It is more efficient to have some thermal inertia   
   inside the fridge and especially freezer so that the thermal control   
   loop doesn't spend its time hunting. A large bottle of water should be   
   enough to provide the thermal inertia to keep things well behaved.   
      
   Any empty one will use more power than a moderately full one but it   
   shouldn't run continuously unless it is installed in one of the inner   
   circles of Hell or the coolant has mostly leaked out.

   The largest possible thermal mass that you can put inside it then. Why   
   are you running a huge empty refrigerator empty in the first place?   
      
   Don't you think that buying a small well insulated fridge suited to the   
   intended usage might be a lot more cost effective?
