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 ...

The use of environmentally damaging gases in air conditioners and refrigerators could become redundant if a new kind of heat pump lives up to its promise. A prototype, described in a study published ...

Heat pumps function similarly to refrigerators or air conditioners, which take warm air from one space and send it to another. In the winter, a heat pump transfers heat from the outdoors inside and, ...

Academics from the Cape Peninsula University of Technology in South Africa have designed a PV-powered integrated heat pump and cooling system to heat up food and refrigerate drinks. The system uses a ...

Finite-time thermodynamics (FTT) is an advanced field that addresses the inherent irreversibilities associated with real-world energy conversion processes. Unlike classical thermodynamics which ...

A new physics discovery may lead to more efficient refrigerators, heat pumps and airport scanners, among many possible uses –- perhaps within a decade.The refrigerator of 2024 may be cooled not by ...

With global warming becoming an urgent issue, heating our homes efficiently -- and sustainably -- has taken center stage. As winters become more unpredictable (and unexpectedly harsh), finding ...
