Abstract

A process for cold and/or heat production using carbon dioxide, a solvent for carbon dioxide and a condensable fluid (F), comprising conducting an absorption/condensation step wherein carbon dioxide is absorbed in the solvent and the gaseous fluid (F) is condensed, a step of separation of the resultant liquid phases, a desorption step for the CO.sub.2 solution, a mixing step and an evaporation step for the condensed fluid (F).
