Weak Solution and Stage Absoption Heat
To increase the performance of absorption heat transformers, there has been a continuous effort to obtain high temperature lift and COP by using the exhaust gas as the heat source. A two-stage absorption heat transformer (TAHT) is one kind of advanced heat transformer in which it is possible to achieve a higher absorber temperature. A recent study has presented a mathematical model of a two-stage heat transformer with a solution heat exchanger operating with water/sulphuric acid. Rivera et al. has proved that the double configuration can have a higher absorber-temperature, but the COP is less than that for the single-stage ...
