  • Absorption refrigerating system and working mixture for said system
    Patent number: 6141987
    Abstract: An absorption refrigeration system which utilizes absorption with a double separating effect where the pressure of the condenser (K2) is offset relative to the pressure of the second generator (G2). In this system, absorption of the working mixture is achieved using methanol as the refrigerating agent and a compound having a methylphenol group as a solvent. The system is useful for producing cold or heat, particularly for the air conditioning of elementary units of a building.
