The invention relates to an absorption refrigerating machine (1) comprising a circulated working substance, in different mixing ratios of a solvent and a refrigerant depending on the circulating process, a high-pressure area (2) with a generator (14) generating the refrigerant from the solvent while heat is supplied, as a first component, and a condenser (20) condensing generated refrigerant, as a second component, a low-pressure area (3) with an evaporator (25) evaporating the refrigerant while heat is extracted, as a third component, and an absorber (28) for the absorption of refrigerant vapour in the solvent, as a fourth component, a refrigerant expansion valve (24), arranged between the high-pressure area and the low-pressure area, a solvent expansion valve (30), arranged between the high-pressure area and the low-pressure area, and also a working substance pump (8), arranged between the absorber and the generator, and also possibly a deflegmator (10), arranged between the generator and the condenser, as a fifth component, and also possibly a solvent heat exchanger (23), as a sixth component. In order to lower the costs of an absorption machine and increase its efficiency, at least one component is formed in itself or in combination with at least one other component as a plate heat exchanger.
