Abstract (en)

A method of transferring a working medium in a liquid phase from a low-pressure area to a high-pressure area, in which a working medium is in the gaseous phase or supercritical state, is characterized in that at least one working space (P) is moved and as a result of the moving the at least one working space (P) is opened at the CG stage in the high-pressure area and the working medium in the liquid phase, having a much higher density than the surrounding working medium in the gaseous phase or supercritical state, is caused to drop from this at least one working space (P), whereby the working medium in the liquid phase is replaced in the working space (P) by the working medium in the gaseous phase or supercritical state.A device (15) for transferring a working medium in a liquid phase from a low-pressure area to a high-pressure area, characterized in that it comprises at least:- drum (5), driven by drive (19), rotating and arranged in housing (11, 12), in which there is at least one working space (P),- bearing shafts (9) connected to drum (5) and arranged in housing (11, 12),- two floating plates (6) with openings (GC, CG) arranged in housing (11, 12) and connecting working space (P) to:- the high-pressure area upstream and downstream of the evaporator, where the working medium in the liquid phase is exchanged in the working space for the working medium in the gaseous phase or supercritical state- the area upstream and downstream of condenser (17), where the working medium in the gaseous phase or supercritical state is exchanged in working space (P) for the working medium in the liquid phase.A system comprising a device for transferring a working medium in a liquid phase from a low-pressure area to a high-pressure area, an evaporator, a condenser and at least one working device characterized in that device (15) for transferring a working medium in a liquid phase from a low-pressure area to a high-pressure area comprises at least:-drum (5), driven by drive (19), rotating and arranged in housing (11, 12), in which there is at least one working space (P),- bearing shafts (9) connected to drum (5) and arranged in housing (11, 12),- two floating plates (6) with openings (GC, CG) arranged in housing (11, 12) and connecting working space (P) to:- the high-pressure area upstream and downstream of the evaporator, where the working medium in the liquid phase is exchanged for the working medium in the gaseous phase or supercritical state- the area upstream and downstream of the condenser (17), where in the working space (P) the working medium in the gaseous phase or supercritical state is exchanged in the working space for the working medium in the liquid phase.
