Abstract
The invention relates to compositions which contain a chlorofluorinated ether and at least one solvent, and their use in thermal absorption apparatus for the generation of heat or cold. In the compositions according to the invention, the chlorofluorinated ether is 1-difluoromethoxy-1,1,2-trifluoro-2-chloroethane (enflurane: CF.sub.2 H--O--CF.sub.2 CHFCl) and the solvent is selected among aromatic esters and .omega.,.omega.'-dialkylated polyoxyethylene glycols. The present invention can be particularly applied in the heating and refrigeration areas using absorption systems such as, for example, heat pumps.
