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 ...

Forty percent of the energy in the fuel used in cars and trucks escapes through the tailpipe as waste heat. Thermoelectric generators convert this heat to electricity, reducing alternator loads and ...

A research team led by Prof. Guo Bin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has designed and optimized an organic Rankine cycle (ORC) system specifically for ...

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 ...

Geothermal heat exchangers almost always use condenser water or glycol as the heat transfer medium — and, sometimes, refrigerant. Wastewater heat recovery systems typically preheat domestic cold water ...
