Embodiment Construction

[0049] figure 1 A schematic process block diagram of a thermodynamic cycle process as known in principle from the prior art is shown. When used as a heat pump as shown, the gaseous working medium is firstly compressed isentropically by means of the compressor 1 . Then, isobaric heat dissipation is carried out through the heat exchanger 2, so that the heat energy with a very high temperature is released to the heating circuit through the circuit (water, water / antifreeze or other liquid heat transfer medium).

[0050] An isentropic decompression is then carried out in a decompression unit 3 designed as a turbine, whereby the mechanical energy is recovered. An isobaric heat supply is then carried out via a further heat exchanger 4 , whereby low-temperature thermal energy is fed to the system via a circuit (water, water / antifreeze, brine or another liquid heat transfer medium). In this case, thermal energy is usually supplied from well water from so-called depth probes, for whi...

Abstract

Method for converting thermal energy at a low temperature into thermal energy at a relatively high temperature by means of mechanical energy, and vice versa, with a working medium which runs through a closed thermodynamic circulation process, wherein the circulation process has the following working steps: —reversible adiabatic compression of the working medium, —isobaric conduction away of heat from the working medium, —reversible adiabatic relaxing of the working medium, —isobaric supply of heat to the working medium, and wherein the increase or decrease in pressure of the working medium is produced during the compression or relaxing, increasing or decreasing the centrifugal force acting on the working medium, with the result that the flow energy of the working medium is essentially retained during the compression or relaxing process.

Description

technical field [0001] The invention relates to the conversion of low-temperature thermal energy into higher-temperature thermal energy by means of mechanical energy using a working medium flowing through a closed thermal cycle process and vice versa, that is to say, the conversion of high-temperature thermal energy into A method of thermal energy at low temperatures, wherein the cyclic process has the following working steps: [0002] - reversible adiabatic compression of the working medium; [0003] - Dissipate heat isobarically from the working medium; [0004] - Reversible adiabatic decompression of the working medium; [0005] - Heat isobarically supplied to the working medium. [0006] Furthermore, the invention relates to a device for carrying out the method according to the invention, which device has a compressor, a pressure reduction unit and a heat exchanger for heat supply or heat dissipation, respectively. Background technique [0007] Various devices are k...
