Based on the performance analysis of the single stage, the two-stage and the double absorption heat transformer, a new ejection-absorption heat transformer is presented and analyzed in this paper. The results show that it has a simpler configuration than the double absorption heat transformer...

Low concentration methane, emitted from coal mines, landfill, animal waste, etc. into the atmosphere, is not only a greenhouse gas, but also a waste energy source if not utilised. Methane is 23 times more potent than CO2 in terms of trapping heat in the atmosphere over a timeframe of...

The absorption heat transformer (AHT) is a promising system for recovering waste heat. It can effectively recover about 50% of the waste heat and reuse it in industrial processes. However, there exists a need for identifying suitable working fluid combinations and for evaluating their relative...
