Cold and/or heat are produced by a process operated according to the absorption technique and which comprises at least two successive absorption steps of the solute vapor in a solvent. At least one part of the heat evolved in the first absorption step is used to partially vaporize the solution recovered from the second absorption step, said second absorption step being operated at a lower temperature than the first absorption step. The solution recovered from said second absorption step is brought to higher pressure and partially vaporized with use of the heat evolved in the first absorption step. The resultant solution is then desorbed in a countercurrent contact zone wherein the solution is contacted with a vapor phase generated by heating of this solution. |
