A condensation system for the condensation of turbine exhaust steam has a condenser installation (25) in which a surface condenser (30) and a direct-contact condenser (35) work in combination. In this case, the two condensers (30, 35) are either arranged in a single common housing or are each arranged in a separate housing. In one embodiment, the condenser installation (25) is connected in a circulation circuit for the cooling media to a wet-dry cooling tower or hybrid cooling tower (40). In this case, the cooling water of the surface condenser (30) is recooled in the wet part (42) and the cooling condensate of the direct-contact condenser (35) is recooled in the dry part (41) of the hybrid cooling tower (40). The condensation system according to the invention has the advantages that the manufacturing costs of the condenser installation are reduced by reducing the tube heating surface, the power of the turbine is increased by reducing the condenser pressure, no fog is caused by the hybrid cooling tower (40), and a smaller quantity of make-up cooling water is required.
