Abstract
An absorption power cycle is disclosed which achieves a closer match to heat source temperature glide, and also lower heat source exit temperatures, and hence higher conversion efficiencies, in practical equipment. Referring to FIG.,, two separate absorbers (,and,) are provided, each with a pumping path for a different concentration absorbent liquid to a different temperature location within counter-current high-pressure desorber,. Heat source,heats the high-pressure desorber,and superheater,in parallel, and subsequently heats intermediate-pressure desorber,. Dotted lines in the figures signify vapor.
