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 ...

The proposed system uses waste heat by thermally coupling a water lithium bromide absorption heat transformer with a water vapor compression heat pump. It reportedly achieved a temperature elevation ...

Chinese scientists have unveiled a new ultra-high-temperature heat pump with no moving parts that could one day allow sunlight or industrial waste heat to power some of the world’s most ...

A research team led by scientists from the Chinese Academy of Sciences (CAS) has developed a novel heat-driven thermoacoustic heat pump (HDTAHP) that is reportedly capable of achieving higher ...
