Genuinely curious - when did this become a thing? I have a couple of relatively recent fridges (less than 10 yrs old, and same model still sold today) that constantly cycle on/off, and spend more time off than they do on.
I'd imagine a variable speed system (like are available in inverter-based heat pumps today) could be designed to run nearly constantly, but the variability of things like room temp, fridge loading (empty fridges are less efficient than full ones), open/closing doors, and the addition of warm/hot things in the fridge would make it so there's always a need for cycling at some level...
- Scoundreller 2y agoFrom what I’ve seen, they’re usually marketed as “inverter fridges”. And yeah, at least the fan turns off when you open the door, and I’d imagine if you put a bunch of ice into the fridge, it wouldn’t need to run at all for a while. Meanwhile my local electric code (Ontario Canada) still requires a dedicated circuit for the fridge, which will now basically hum along at 1-2amps and never brownout/trip a circuit. What a waste.
- fomine3 2y agoSo we should just buy efficient inverter refrigerator, rather than add 48VDC.
- Scoundreller 2y agoAt the end of the day, they’re going to (possibly transform the voltage), rectify and AC input into DC and chop it up to get variable-frequency drive. I kinda wonder how low or high voltage it could run on out-of-the-box but there might be other stuff that runs off straight 120V (e.g. defrost cycle).
