USSR made compact fridges like that, called Морозко. They are still made. No moving parts, very quiet.

- VladVladikoff 1mo agoMan WTH? Now I want one. I hate how loud my fridge is!
- HPsquared 1mo agoThey're not energy efficient so I'm not sure that type of fridge is available to buy now.
- lstodd 1mo agoEnergy efficiency is secondary, that can be mitigated by solar power plus some thermal mass inside. That is actually most efficient use of solar from my pow. Their bane is hydrogen partial pressure dropping due to it leaking through the metal of the tubes. That .. is problematic. OTOH it'll last for like 20 years before you'd need to replenish.
- RobGR 1mo agoThe Einstein-Szilard device doesn't use hydrogen, did the USSR device use it ?
- tingletech 1mo agoin the US you can still buy hydrogen/ammonia/water gas absorption refrigerators such as "EZ Freeze". Propane/Natural Gas refrigerators use this cycle. I'm sure you can get them all over the world, the cycle is older than the one in the article.
- ninalanyon 1mo agoYou can buy them almost anywhere where there is a need to keep food cold without electricity.
- grumbelbart 1mo agoGet one with an inverter compressor, they are very quiet. They have a compressor that can be run at varying power levels, so instead of having one that goes of noisy at 100%, then sits off for a while, you have one that runs for example at 10% most of the time.
- VladVladikoff 1mo agoInteresting. Is this better or worse for compressor life span?
- grumbelbart2 1mo agoFrom what I know it's better for the life span. Less load, fewer start-stop cycles, less vibration.
- yencabulator 1mo agoUsually that means either a fan or compressor pump is making a metal panel resonate; the pump itself is usually pretty quiet, and the fan is pretty much the same as a PC fan. You can usually add a sticky foam panel to the metal backpanel to eliminate the vibration.
