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.              > Again, the simple question was what contents within the refrigerator       > will retain the cold so that the motor/compressor will only rarely       > come on? The refrigerator is accessed only about once a month.              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?              --       Regards,       Martin Brown              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
