A working procedure of a sorption power cycle for a binary mixture of ammonia and water, with main components of a cycle referred to in the following as the main cycle: - at least one high-pressure desorber (3, 3a, 3b, 3c, 9) to desorb high-pressure vapour of ammonia and water from a strong solution (2, 2a, 2b) that is fed in, - a superheater to superheat a high-pressure vapour of ammonia and water, - a working high-pressure relief apparatus to relieve the high-pressure vapour, - at least one absorber (12a, 13, 14, 14a, 14b) to absorb the relieved vapour, - at least a first solution heat exchanger to transfer heat from the weak solution to the strong solution, - at least one heat source, characterised in that - the weak solution is fed to an absorber (12a, 12b, 13, 13a, 14) working at the lowest pressure level for absorption, and the weak solution is lowered to this pressure level with the aid of at least one throttle valve, - the strong solution is raised to the high pressure level by an absorber (14, 14a, 14b) working at the highest pressure level by means of a first solution pump, - and the strong solution is fed to at least one high-pressure desorber (3, 3b, 9) to be desorbed, - high-pressure vapour is relieved at least in a second section of the relief with partial condensation, - the dew point being exceeded at a pressure of 9.5 to 15 bar - preferably 13.5 bar - and at least some of the high-pressure vapour being relieved to a final pressure of 1.1 to 4 bar - preferably 1.5 to 2 bar, - and the high-pressure vapour to be relieved being set at a water content by weight of 3 to 10 percent - preferably 6%, - and that the water content by weight in the high-pressure vapour and optionally its superheating pressure is such that the vapour content at the end of the relief remains above a drop impact limit in the high-pressure relief apparatus, - the water content by weight being set by at least one of the following procedural steps: - in at least one high-pressure desorber high-pressure vapour is produced at the equilibrium point for the incoming solution, and in at least one high-pressure desorber (3, 9a) high pressure vapour is produced at the equilibrium point for the outgoing solution, - the water content by weight of the high-pressure vapour is established in a rectifier, the rectifier being designed for partial rectification, - the water content by weight of the high-pressure vapour being set by feeding and evaporating solution into the superheater (10, 11). - at least one high-pressure desorber (3, 3a, 3b, 3c, 9) to desorb high-pressure vapour of ammonia and water from a strong solution (2, 2a, 2b) that is fed in, - a superheater to superheat a high-pressure vapour of ammonia and water, - a working high-pressure relief apparatus to relieve the high-pressure vapour, - at least one absorber (12a, 13, 14, 14a, 14b) to absorb the relieved vapour, - at least a first solution heat exchanger to transfer heat from the weak solution to the strong solution, - at least one heat source, - the weak solution is fed to an absorber (12a, 12b, 13, 13a, 14) working at the lowest pressure level for absorption, and the weak solution is lowered to this pressure level with the aid of at least one throttle valve, - the strong solution is raised to the high pressure level by an absorber (14, 14a, 14b) working at the highest pressure level by means of a first solution pump, - and the strong solution is fed to at least one high-pressure desorber (3, 3b, 9) to be desorbed, - high-pressure vapour is relieved at least in a second section of the relief with partial condensation, - the dew point being exceeded at a pressure of 9.5 to 15 bar - preferably 13.5 bar - and at least some of the high-pressure vapour being relieved to a final pressure of 1.1 to 4 bar - preferably 1.5 to 2 bar, - and the high-pressure vapour to be relieved being set at a water content by weight of 3 to 10 percent - preferably 6%, - and that the water content by weight in the high-pressure vapour and optionally its superheating pressure is such that the vapour content at the end of the relief remains above a drop impact limit in the high-pressure relief apparatus, - the water content by weight being set by at least one of the following procedural steps: - in at least one high-pressure desorber high-pressure vapour is produced at the equilibrium point for the incoming solution, and in at least one high-pressure desorber (3, 9a) high pressure vapour is produced at the equilibrium point for the outgoing solution, - the water content by weight of the high-pressure vapour is established in a rectifier, the rectifier being designed for partial rectification, - the water content by weight of the high-pressure vapour being set by feeding and evaporating solution into the superheater (10, 11).
