Abstract: A turbomachine, in particular a gas turbine, is in the traditional manner provided with air cooling of the components that are subject to a high thermal stress. The cooling system (21, 31, 41) is provided with elements through which another medium (25, 35, 45), for example water or steam, can be added to the cooling system during peak demand. This medium displaces cooling air (26, 36, 46) from the cooling system, the air being then available additionally in a heat generator (2, 4). This means that more fuel (12, 13) can be added without increasing the hot gas temperature (T.sub.1, T.sub.3) at the turbine inlet (301, 501), and the power is increased. The quantity of the medium added to the cooling system is controlled by control elements (24, 34, 44) as a function of a control deviation (P.sub.set -P.sub.act) of the power.

Abstract: A combined thermodynamic power and cryogenic refrigeration system using a first and second (binary) working fluid has a low-temperature closed bottoming cycle and either a closed or open topping cycle. In the bottoming cycle a mixture of a first gas such as helium or hydrogen and a low temperature liquid such as liquefied nitrogen is isothermally compressed and then the liquid content is separated. The separated first gas is heated using heat from a second gas or ambient air expanded in the topping cycle and then the heated first gas is adiabatically expanded and supercooled while performing useful work and thereafter is mixed with the separated liquid to serve as a coolant and facilitate rejection of adiabatic heat and to supplement the cool gas/liquid fed to the compressor and thus completes the bottoming cycle. The bottoming cycle functions to cool the second gas during its compression in the topping cycle. The topping cycles are closed or open modified Brayton cycles.
