Claim:
1. An absorption refrigeration machine having an evaporator for evaporating a refrigerant to produce a refrigerant vapor while absorbing beat from a refrigerant agent circuit circulating a refrigerant agent and having an absorber for absorbing the refrigerant vapor through a concentrated, low-refrigerant working substance pair, wherein the evaporator comprises a plurality of evaporation units each having a refrigerant agent channel flowed through by the refrigerant agent and bounded at least in part by a heat-conductive, vapor-tight and liquid-tight wall and having at least one refrigerant channel which is adjacent to the heat-conductive wall, which is acted on by the refrigerant and which is separated from a vapor space at its side disposed opposite the heat-conductive wall by a vapor-permeable, liquid-tight membrane wall; and wherein the absorber comprises a plurality of absorption units each having a coolant channel flowed through by a coolant and bounded at least in part by a heat-conductive, vapor-tight and liquid-tight wall and having at least one absorption channel which is adjacent to the heat-conductive wall, to which the concentrated, low-refrigerant working substance pair is supplied and which is acted on by refrigerant vapor from the vapor space ( wherein a respective evaporation unit and a respective absorption unit are alternately provided in a consecutive arrangement of the plurality of evaporation units and absorption units for forming an integrated evaporator/absorber unit, wherein a respective pair of directly consecutive evaporation and absorption units or absorption units and evaporation units has mutually facing, vapor-permeable, liquid-tight membrane walls; wherein the evaporation units arranged between two absorption units each have a refrigerant channel at at least two mutually opposite sides of the refrigerant agent channel, said refrigerant channel being separated from the refrigerant agent channel by a heat-conductive, vapor-tight and liquid-tight wall and being separated from the vapor space at its side disposed opposite the heat-conductive wall by a vapor-permeable, liquid-tight membrane wall; and wherein the absorption units arranged between two evaporation units each have an absorption channel at at least two mutually opposite sides of the coolant channel, said absorption channel being separated from the coolant channel by a heat-conductive, vapor-tight and liquid-tight wall and being acted on by vapor from the vapor space via a vapor-permeable, liquid-tight membrane wall provided at its side disposed opposite the heat-conductive wall.
