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 ...

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 ...

If defrost isn’t working, something in the chain is broken. This step-by-step approach shows you exactly where to look and what to test.

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 ...

A line of transformers suits heat-sealing applications such as handheld sealers. Available in capacities from 144 VA to 3.0 kVA, the parts offer 115- or 115/230-V input with outputs from 6 to 160 V.
