High efficiency fridge-freezers

[puntloos]

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?

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.

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.

Yep exactly, and I can certainly understand the 'ice hole' being a problem for efficiency I imagine it wouldn't be that bad...

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.

I'm struggling with the Yank term "French Door Refrigerators".

 

Which are the ones we call "American Fridges".

Heh yep. But the video actually touched on many items including the in-door icecube makers. 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....

Apparently Bertazzoni is where it's at, with A+ appliances on the new (??) rating

otherwise there's a few A-C rated ones

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)

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)

Any with a door ice maker / cold water dispenser are basically putting a hole in the freezer door.

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.
