In a given "hour", an empty refrigerator will       run say "12 minutes", starting probably "6 times", and stopping "6 times". A       full refrigerator will start maybe "once" in that hour and run the full "12       minutes".       >       > So yes, the thermal mass (water, soda, beer) will reduce the starts per       hour, potentially letting the compressor last longer (each start reduces       overall life of the system).       >       > Don't worry about "most efficient". Roughly, each pound / kilogram you put       in there will be equivalent. If you are worried about being inert, just use       bricks, car parts, whatever makes sense in your context.       >       > David A.

It increases the thermodynamic efficiency.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
