Abstract
An improvement to absorption heat pumps and refrigerators, which comprises supplying of a first fraction S.sub.1 of a solution S subjected to a desorption step, to a heating and vaporization zone E where the solution S.sub.1 is progressively heated and vaporized in a temperature interval .DELTA. between an initial temperature T.sub.i, and a final temperature T.sub.f, by heat exchange with a fluid external to the desorption zone, while a vapor phase V' and optionally, a liquid phase L' are produced, which phases are separated from each other, and a second fraction S.sub.2 of the solution S is fed to a desorption zone D in which the fraction S.sub.2 and vapor phase V' are contacted to obtain a liquid phase L', phases L' and L' forming the phase L which is recycled to the absorption step.
