Absorption heat transformers are devices with the unique capability of raising the temperature of part of a low grade heat source whilst simultaneously rejecting the rest of the heat at a lower temperature. The gross temperature lift that could be attained in the process depends on the characteristi

✦ Synopsis
In order to increase the temperature lift and efficiency of single-absorption heat transformers there are other possible arrangements. Double-absorption heat transformers have a relatively simple design and smaller size compared to two-stage heat transformers. In this work, the thermodynamic performance of the water/calcium chloride system was modelled for a double-absorption heat transformer. Results indicate that temperature lifts of up to 40 °C are possible with coefficients of performance close to 0)3.

It is proven that a solar absorption heat transformer affected by the irreversibility of finite-rate heat transfer may be modelled as an equivalent combined system consisting of a solar collector and an endoreversible absorption heat transformer, the latter being further treated as a combined cycle
