But why? Cooling has been a solved problem for literally over a century. No Peltier cooler will ever even come close to normal refrigerant-based coolers in efficiency, both in cost and power consumed.

- toast0 1y agoPeltier coolers can do precision better than a compressor. The also work at small sizes/small loads, where a compressor generally needs to be a certain minimum size to be feasible. Do you need those things in a home refrigerator? I suspect not. But it might be handy for lab refrigerators.
- AngryData 1y agoYou can actually get surprisingly small compressors now the last few year. There are a few compressor driven ice coolers available now that are likely worth the effort and price if you need a boost in cooling capacity or battery life over the cheaper peltier equivalents. And they are also used by some people for large bulky cosplay and costume outfits that are otherwise just a super insulated hotbox. Obviously they still have a minimum size limit, but I think many people would be surprised at how small you can get them now.
- ranger_danger 1y agoAre you implying that "normal refrigerant-based coolers" are somehow always the most appropriate solution for any cooling task?
- okanat 1y agoNot the poster but yes. Compressors use phase change which is fundamentally better way of transferring heat. Solids like peltiers will always leak more heat than liquid to gas phase change. Peltiers cannot get the same efficiency because of physics.
- ranger_danger 1y agoSo a compressor that's too big to fit and/or too noisy/vibrating for a particular application is still somehow the most appropriate solution?
