What's Going on with The New Super Efficient Fridges

I'm just looking for a new fridge as our current one is frosting a lot. I found out that there are 2 fridges that stand out from the rest in terms of efficiency (Haier HRF420BEC - 8 stars, Hisense HRBM418D - 7 stars). Wondering if anyone knows of any significant improvements in this area. I'm a nerd and just looked into the specs of the two fridges, I couldn't really tell if there is any major new tech, all I can see is they're both using R600a/48g, while their less efficient ones use R600a/55g. But I don't have enough knowledge in refrigerant to tell the differences, and hope to have someone shedding some light here.

Update: I've got a HRF420BEC delivered yesterday, it's been good so far.

    Better heat exchange, compressor efficiency, and insulation probably makes new fridges much more efficient than an average one from 10 years ago. it should tell you on the fridge how much energy it uses.

      Yeah I get it, I'm just curious if there is any new technology that makes the difference. Mainly because no other major brands (e.g. Electrolux/LG/Westinghouse) have a model close to that efficiency.

      Edit: I'm also comparing these with the 2-3 y.o 5-star fridges (e.g. https://www.electrolux.com.au/fridges-and-freezers/fridges/e…), not the 10 yo ones.

    What's the kWh usage? Stars are meaningless really with so many variables.

    • Tmbao95 on 04/06/2024 - 11:06

      They're advertised as 155 and 171 kwh/year respectively.

      CEC numbers are about 10% higher

        Litreage of each?

          155kwh/year: 8 star - 433L Haier
          171kwh/year: 7 star - 417L Hisense

            @Tmbao95: Just had a quick look at the designs, aside from any changes to refrigerants etc, my gut says design would impact it.

            Im looking at Hitachi fridges atm.

            An example - Japanese style (highly compartmentalised, freezers down the bottom)

            615L - 400kWh
            670L - 420kWh

            But flick to their traditional European 4 French door style

            638L - 542kWh

            Still freezers down the bottom but design wise it would take way more effort to cool.

        That's decent innit?

    HRF420BEC features vacuum insulated panels, outperforms PU foam

    Inverter models allow the compressor to run slowly which increases efficiency.

      I've also got a well dated Samsung fridge 3.5 star and still featured as inverter :D. Is it standard nowadays

    I have the Hisense fridge, or a near identical earlier revision. It is a noisy POS. Would not recommend.

    • Tmbao95 on 04/06/2024 - 18:28

      Interesting, is it a deal breaker for you

      • Aureus on 04/06/2024 - 21:02

        Yeah.

        Obviously this is a sample size of one, but I wouldn't touch Hisense appliances again.
