puntloos Posted July 13, 2022 Share Posted July 13, 2022 In a bored moment I was browsing fridge freezers and I noticed that my favorites all had an energy rating of F which clearly isn't great. Their amazeballs linear inverter, it does nothing?? - https://www.lg.com/uk/fridge-freezers/lg-gsi960pzvv# Now one feature I tend to look for in freezers is an ice maker with external ice dispenser, which punches a meaningful hole through the insulation, but I was assuming that it would be mitigated in a good amount by that nozzle effectively pointing downward which means the cold really sits at the bottom of the freezer and doesn't really have a great path. This video below explains it pretty nicely. What gives? Is perhaps the energy efficiency rating comparing the entire box no matter if it's a single box or a huge multi-door device with much more space to cool? As far as I can tell the energy rating stupidly (imho?) seems to just look at the raw power draw of the device, not power-draw-per-liter-volume? Or does anyone know a "A/B rated" double door american style fridge freezer? Link to comment Share on other sites More sharing options...
joe90 Posted July 13, 2022 Share Posted July 13, 2022 Ha I liked that, I was always told cold air flows out of the door like water which is why a chest freezer is more efficient. Link to comment Share on other sites More sharing options...
JohnMo Posted July 13, 2022 Share Posted July 13, 2022 The A to whatever ratings all got changed about a year ago, think to old A is something like an F. All fridges were A+ or A+++++ so was very much meaningless. Link to comment Share on other sites More sharing options...

Yep exactly, and I can certainly understand the 'ice hole' being a problem for efficiency I imagine it wouldn't be that bad... Link to comment Share on other sites More sharing options...
Ferdinand Posted July 13, 2022 Share Posted July 13, 2022 The change of energy scale is the big difference. A good fridge or freezer is now something like a C. When I looked the only things that made an A were wine coolers. For a comparison perhaps look at annual power consumption. Link to comment Share on other sites More sharing options...
Ferdinand Posted July 13, 2022 Share Posted July 13, 2022 I'm struggling with the Yank term "French Door Refrigerators". Which are the ones we call "American Fridges". 1 Link to comment Share on other sites More sharing options...

I will have to do some soul searching on how important it is to my life. As you can imagine in the current week of 27+C temps expected, being able to get a glass of chilled+iced water without opening the fridge and rummaging around with the ice tray is .. nice. But then again, an ice compartment with a small but easily accessible scoop might be not much worse, and much more energy efficient.... 1 Link to comment Share on other sites More sharing options...
joth Posted July 13, 2022 Share Posted July 13, 2022 Apparently Bertazzoni is where it's at, with A+ appliances on the new (??) rating https://www.appliancecity.co.uk/refrigeration/fridge-freezers/?filter_energy-rating=energy-aa otherwise there's a few A-C rated ones https://www.appliancecity.co.uk/refrigeration/fridge-freezers/?filter_energy-rating=energy-a https://www.appliancecity.co.uk/refrigeration/fridge-freezers/?filter_energy-rating=energy-b https://www.appliancecity.co.uk/refrigeration/fridge-freezers/?filter_energy-rating=energy-c 1 Link to comment Share on other sites More sharing options...

No they're different, American puts the fridge and the freezer side by side (each full height) with a vertical line splitting them , but French has the fridge (generally double "french" doors) stacked on top of the freezer (typically opening as drawers) https://www.appliancecity.co.uk/news/updates/our-favourite-slim-french-style-fridge-freezers/ Edited July 13, 2022 by joth Link to comment Share on other sites More sharing options...
puntloos Posted July 14, 2022 Author Share Posted July 14, 2022 Just some randomish research: https://www.appliancecity.co.uk/refrigeration/fridges/integrated-fridges/liebherr-irbb4170-122cm-integrated-biofresh-larder-fridge/ - most efficient full height(ish) integrated fridge - 72kwh/annum - 191L https://www.appliancecity.co.uk/refrigeration/freezers/integrated-freezers/liebherr-sifnd4155-122cm-integrated-in-column-frost-free-freezer/ - most efficient full height(ish) integrated freezer - 166kwh/annum - 129L So total - 238kwh/annum for 320L https://www.appliancecity.co.uk/refrigeration/american-style-fridge-freezers/lg-gsxv90bsae-door-in-door-instaview-american-fridge-freezer-stainless-steel/ - most efficient american fridge freezer - 348kwh/annum - 635L So "per liter" the american E-rated beast is actually much more efficient 0.54kwh/L than having two A/D rated devices paired up (0.74kwh/L) Link to comment Share on other sites More sharing options...
George Posted July 14, 2022 Share Posted July 14, 2022 Any with a door ice maker / cold water dispenser are basically putting a hole in the freezer door. Link to comment Share on other sites More sharing options...

You'd think but both the video I attached above, as well as the numbers I list here don't seem to bear this out. Link to comment Share on other sites More sharing options...
