Abstract: In a method for the generation of heat using a heat pump in which a heat carrier fluid is heated by a heat exchanger and compressed with temperature increase in a subsequent compressor, heat is delivered therefrom to a heat-admitting process; the fluid is then expanded in a gas turbine, producing work, and afterwards its residual heat is delivered to a thermal power process, the maximum temperature of the energy sources of which, that provide work for the compressor, lies below the temperature of heat delivery. The main heat source can consist of an exothermic chemical or nuclear reaction and the heat-admitting process can be a coal gasification process. The work in the compressor is furnished essentially by the gas turbine and the thermal power process.

Abstract: A controlled exhaust driven turbo-supercharger is designed for an engine revolution below the nominal speed or revolutions of the engine to be supercharged and has an impellerless guidance device. A control device is provided which responds to the supercharger speed or a nominal characteristic (supercharger pressure) derived therefrom whereby the adjustment member for the control device is coupled with a control means which enlarges the flow cross section of the guidance device during the increasing supercharger speed.
