A multicomponent working fluid consisting of a lower boiling point component ''solute'' dissolved in higher boiling components ''absorbant'', is pumped as a liquid (15.1) to a high working pressure. The liquid is heated up in a steam generator (9.1) and is partially evaporated, splitted into a gaseous working fluid (14.1) consisted mainly from the lower boiling component and a lean solution (13.1) with respect to lower boiling component. After successive reheatings and expansions the gaseous working fluid is absorbed by the lean solution returning to absorber (14.1). The purpose of this procedure is to increase the thermal efficiency of the cycle by expanding the gaseous working fluid to a low temperature and by reducing the heat amount rejected to ambient. |
