The invention relates to an absorption refrigerant machine having an evaporator for evaporating a refrigerant while heat is absorbed from a coolant circuit and an absorber for absorbing the refrigerant vapor by means of the concentrated, low-refrigerant pair of working substances. Said absorption refrigerant machine is characterized in that the evaporator comprises at least one evaporating unit having a coolant channel, through which the coolant flows and which is bounded at least partially by a heat-conducting, vapor- and liquid-tight wall, and having at least one refrigerant channel, which is adjacent to the heat-conducting wall and which is loaded with the refrigerant and which is separated from a vapor chamber by a vapor-permeable, liquid-tight membrane wall on the side of the refrigerant channel facing the heat-conducting wall, and that the absorber comprises at least one absorption unit having a cooling-medium channel, through which a cooling medium flows and which is bounded at least partially by a heat-conducting, vapor- and liquid-tight wall, and having at least one absorption channel, which is adjacent to the heat-conducting wall and to which the concentrated, low-refrigerant pair of working substances is fed and which is loaded with refrigerant vapor from the vapor chamber by means of a vapor-permeable, liquid-tight membrane wall provided on the side of the absorption channel facing the heat-conducting wall. |
