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 ...

Heat pumps for both space and water heating will be required in most new homes in the state of Washington beginning next July. The mandate, which applies to single-family and smaller multi-family ...
