Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
212 words
In a method for the deliverance of heat by means of a heat pump of the type wherein a heat carrier fluid is heated by a heat source; said heat carrier fluid is compressed with temperature elevation in a compressor subsequent to the heat source; heat is delivered from said heat carrier fluid to a heat-admitting process (heat delivery); and said heat carrier fluid is allowed to expand in a gas turbine furnishing a part of the compression energy, the improvement wherein said heat carrier fluid has a temperature of more than about 800° C. before said heat delivery and is delivered to a heat-admitting process running only at temperatures above about 800° C. with a satisfactory rate of reaction, and work collectively provided to drive the compressor, as far as not being furnished by said gas turbine, is furnished mainly by the thermal energy of the always gaseous heat carrier fluid which is still available after the heat delivery in that said heat carrier fluid delivers said thermal energy to a thermal power process which furnishes work to drive said compressor, with or without some of the heat energy which can be delivered by said heat-admitting process and which is available at a temperature below the temperature of said heat delivery.
