Improvement in the step of desorption of the pumps a heat and is absorption refrigerating machines

摘要

An improvement to absorption heat pumps and refrigerators, which comprises supplying of a first fraction S1 of a solution S subjected to a desorption step, to a heating and vaporization zone E where the solution S1 is progressively heated and vaporized in a temperature interval DELTA between an initial temperature Ti, and a final temperature Tf, 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 S2 of the solution S is fed to a desorption zone D in which the fraction S2 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.
