Abstract:
An absorption refrigeration machine according to the Platen-Munters system, with a generator (7) for evaporating a refrigerant in a solvent, a solvent separator (2) in which the separation of the solvent from the refrigerant is performed, a condenser (3) for liquefying the refrigerant, an evaporator (4) in which the refrigerant is evaporated using a dry gas while being cooled, optionally with a first gas heat exchanger (6), and an absorber (5) in which the evaporated refrigerant is added to the depleted mixture of refrigerant and solvent which is then again evaporated in the generator (7), characterized in that the output of the evaporator (4) or the output of the optional first gas heat exchanger (6) which is arranged downstream of the evaporator (4) and the output of the generator (7) open into a bypass (8) leading into the absorber (5), with the mixture consisting of evaporated refrigerant and dry gas which arrives from the evaporator (4) via the first gas heat exchanger (6) being transferred to the output of the generator and from there through the bypass (8) where the gas mixture is brought into contact with the hot, partially degassed solution coming from the generator (7) and withdraws further refrigerant from the same.
