A group of researchers led by the Chinese Academy of Sciences (CAS) has developed a heat-driven thermoacoustic refrigerator/heat pump (HDTAR/HDTAHP) for high heating-temperature operation. They ...

Researchers in Singapore have built a refrigerator that's just three atoms big. This quantum fridge won't keep your drinks cold, but it's cool proof of physics operating at the smallest scales.

The heat transfer "fluid" doesn't need to be a liquid. Blowing (not sucking) air through the copper tube with a fan that's switched on and off by the temperature in the "fridge" side would work fine ...

Absorption heat transformers (AHTs) are advanced thermal systems designed to upgrade low-grade waste heat to higher, more useful temperature levels. By exploiting the thermodynamic properties of ...
