Abstract

Sposób przenoszenia czynnika roboczego w fazie ciekłej z obszaru o niskim ciśnieniu do obszaru o wysokim ciśnieniu, w którym to obszarze czynnik roboczy znajduje się w fazie gazowej lub stanie nadkrytycznym, charakteryzuje się tym, że na etapie CG otwiera się przynajmniej jedną przestrzeń roboczą (P) w obszarze wysokiego ciśnienia i powoduje się opadanie z tej przynajmniej jednej przestrzeni roboczej (P) czynnika roboczego w fazie ciekłej, mającego znacznie większą gęstość niż otaczający go czynnik roboczy w fazie gazowej lub w stanie nadkrytycznym, przy czym w przestrzeni roboczej (P) zastępuje się czynnik roboczy w fazie ciekłej przez czynnik roboczy w fazie gazowej lub w stanie nadkrytycznym. Urządzenie (15) do przenoszenia czynnika roboczego w fazie ciekłej z obszaru o niskim ciśnieniu do obszaru o wysokim ciśnieniu charakteryzuje się tym, że zawiera co najmniej: napędzany przez napęd (19), wirujący i usytuowany w obudowie (11, 12) bębenek (5), w którym znajduje się przynajmniej jedna przestrzeń robocza (P), usytuowane w obudowie (11, 12), połączone z bębenkiem (5) wały z łożyskami (9), usytuowane w obudowie (11, 12) dwie płytki pływające (6) z otworami (GC, CG) łączącymi przestrzeń roboczą (P) z: obszarem wysokiego ciśnienia przed i za parownikiem (16), gdzie w przestrzeni roboczej (P) czynnik roboczy w fazie ciekłej jest wymieniany na czynnik roboczy w fazie gazowej lub w stanie nadkrytycznym, obszarem przed i za skraplaczem (17), gdzie w przestrzeni roboczej (P) czynnik roboczy w fazie gazowej lub w stanie nadkrytycznym jest wymieniany na czynnik roboczy w fazie ciekłej. Układ zawierający urządzenie do przenoszenia czynnika roboczego w fazie ciekłej z obszaru o niskim ciśnieniu do obszaru o wysokim ciśnieniu, parownik, skraplacz i co najmniej jedno urządzenie wykonawcze, charakteryzuje się tym, że urządzenie (15) do przenoszenia czynnika roboczego w fazie ciekłej z obszaru o niskim ciśnieniu do obszaru o wysokim ciśnieniu zawiera co najmniej: napędzany przez napęd (19), wirujący i usytuowany w obudowie (11, 12) bębenek (5), w którym znajduje się przynajmniej jedna przestrzeń robocza (P), usytuowane w obudowie (11, 12), połączone z bębenkiem (5) wały z łożyskami (9), usytuowane w obudowie (11, 12) dwie płytki pływające (6) z otworami (GC, CG) łączącymi przestrzeń roboczą (P) z: obszarem wysokiego ciśnienia przed i za parownikiem (16), gdzie w przestrzeni roboczej (P) czynnik roboczy w fazie ciekłej jest wymieniany na czynnik roboczy w fazie gazowej lub w stanie nadkrytycznym obszarem przed i za skraplaczem (17), gdzie w przestrzeni roboczej (P) czynnik roboczy w fazie gazowej lub w stanie nadkrytycznym jest wymieniany na czynnik roboczy w fazie ciekłej.A method of transferring a working medium in the liquid phase from a low-pressure area to a high-pressure area, in which area the working medium is in the gas phase or supercritical state, is characterized in that at least one working space (P) is opened at the CG stage in a high-pressure region and causing at least one working space (P) to fall from said working medium in the liquid phase having a significantly higher density than the surrounding working medium in the gaseous or supercritical state, wherein the working space (P) is replaced by working medium in the liquid phase by working medium in the gas phase or in the supercritical state. The device (15) for transferring the working medium in the liquid phase from a low-pressure area to a high-pressure area is characterized by the fact that it contains at least: a drum (5) driven by the drive (19), rotating and located in the housing (11, 12). ), in which there is at least one working space (P), shafts with bearings (9) located in the housing (11, 12), connected to the drum (5), two floating plates (6) located in the housing (11, 12) with openings (GC, CG) connecting the working space (P) with: the high pressure area before and after the evaporator (16), where in the working space (P) the working medium in the liquid phase is exchanged for the working medium in the gas phase or in the supercritical state , the area before and after the condenser (17), where in the working space (P) the working medium in the gas phase or in the supercritical state is exchanged for the working medium in the liquid phase. The system comprising a device for transferring the working medium in the liquid phase from a low-pressure area to a high-pressure area, an evaporator, a condenser and at least one actuator is characterized in that the device (15) for transferring the working medium in the liquid phase from an area of low pressure to the high pressure area contains at least: a drum (5) driven by the drive (19), rotating and located in the housing (11, 12), in which there is at least one working space (P), located in the housing (11). , 12), shafts with bearings (9) connected to the drum (5), located in the housing (11, 12), two floating plates (6) with holes (GC, CG) connecting the working space (P) with: the high pressure area upstream and after the evaporator (16), where in the working space (P) the working medium in the liquid phase is exchanged for the working medium in the gas phase or in the supercritical state - the area before and after the condenser (17), where in the working space (P) the working medium in in the gas phase or in the supercritical state is exchanged for the working medium in the liquid phase.
