Yes, no motor, no hum, no fan noise. If you and a adsorption refrigerator were in a Anechoic chamber your heart beat would be the loudest sound there.

I found one at a junk store for $20, They use the ancient system of "Adsorption" refrigeration. It is a closed system of ammonia, water and hydrogen. that cools without a motor. It is the same type as the old Servel gas fridges except instead of using heat from burning gas it uses a electrical heating element. It's maximum power consumption is 60w. It cools better than a Peltier yet it is even quieter.
The mini bar fridges were the kind that was part of the German stereos.
The type of refrigeration cited here are the same type used in camper fridges that run on 120vac, 12vdc and propane.

In Romania the most spread model was an 'Fram'. A model with locking sistem... the final step in life for some lot of kids
I never seen an abortion system refrigerator working.

Well the gases and liquids are inside steel tubing, to see it work you would have to have X-ray vision! lol
A youtuber named v8jagnut took the absorption cooling unit out of a RV fridge cabinet and tried to make a water chiller out of it. the video shows a nice visual of the cooling system operating with frost on the evaporator..
