Sustainability Post #20 — Efficient Refrigerators

Filed under: Information — Tags: , — Topher @ 4:57 pm

The recommendation often seen is that you should replace any refridgerator made before 1993.

Here is an extensive list from Energy Star.

The quick things to take away, 1) Top or bottom freezer beats side by side, 2) Manual defrost beats Automatic defrost (if you defrost once a year),  3) Through the door whatever sends energy out the window.  Also beware of the energy guide labels, they compare similar fridges thus a ‘best’ which is large, auto defrost, with through the door ice and water, will use much more electricity than a ‘worst’ which is small and manual.  Use the kWh / year as your number for comparison.  If you have a chest freezer, a refrigerator only will be a big win (be sure to buy based on the capacity of comparable refrigerator portions of combo units.

Well, all of those can be handily beaten by this idea ( a conversion of a chest freezer into a refrigerator):




Instead of the custom made thermostatic control you can use this beer making fridge control.
