Centrifuge refrigeration via magnetocaloric system

A centrifuge (10), comprising:

• a cylindrical safety vessel (30) includes a cylindrical vessel wall (32);
• said cylindrical vessel wall (32) includes an interior wall (40) and an exterior wall (44), said interior wall (40) and said exterior wall (44) of said cylindrical safety vessel form an unimpeded cylindrical intermediate space (48);
• said cylindrical safety vessel (30) includes an interior space (31);
• a rotor (17) is arranged in said interior space (31) of said cylindrical safety vessel (30), said rotor is connected via a drive shaft (20) to a drive device (22);
• said drive shaft (20) extends through said cylindrical safety vessel (30) to rotate said rotor;
• said interior wall (40) of said cylindrical safety vessel faces said rotor (17);
• said interior wall (40) being in contact with said interior space (31), and heat is generated by said rotating rotor in said interior space (31);
• a magnetocaloric refrigeration unit (102);
• a first fluid passageway through said magnetocaloric refrigeration unit (102) and a second fluid passageway through said magnetocaloric refrigeration unit (102);
• a first cooling circuit (111);
• a first heat transfer medium (19) resides in said first cooling circuit (111);
• said first cooling circuit includes said unimpeded cylindrical intermediate space (48) of said cylindrical safety vessel and said first cooling circuit includes said first fluid passageway through said magnetocaloric refrigeration unit (102);
• said first cooling circuit includes a first set of low pressure lines (111) for an operating pressure of up to 3 bar;
• said first set of low pressure lines of said first cooling circuit (111) being interconnected with said unimpeded cylindrical intermediate space (48) of said cylindrical safety vessel and said low pressure lines of said first cooling circuit (111) being interconnected with said first fluid passageway of said magnetocaloric refrigeration unit;
• said first heat transfer medium in direct contact with said interior wall (40) and said exterior wall (44) of said cylindrical safety vessel, and heat is transferred from said interior space (31) through said interior wall of said cylindrical safety vessel and to said first heat transfer medium;
• a first pump (14a) for pumping said first heat transfer medium (19) through said first set of low pressure lines (111), said unimpeded cylindrical intermediate space (48) of said cylindrical safety vessel, and said first fluid passageway of said magnetocaloric refrigeration unit;
• a second cooling circuit (113);
• said second cooling circuit includes a second set of low pressure lines (113) for an operating pressure of up to 3 bar;
• a heat exchanger in said second cooling circuit (113);
• a second heat transfer medium resides in said second cooling circuit (113);
• said second set of low pressure lines (113) interconnected with said heat exchanger and with said second fluid passageway of said magnetocaloric refrigeration unit;
• a second pump (14b) for pumping said second heat transfer medium through said second set of low pressure lines (113), said heat exchanger (106) and said second fluid passageway of said magnetocaloric refrigeration unit (102);
• said magnetocaloric refrigeration unit extracts heat from said first heat transfer medium (19) of said first cooling circuit as it passes through said first fluid passageway of said magnetocaloric refrigeration unit (102) and feeds said heat to second heat transfer medium in said second fluid passageway of said magnetocaloric refrigeration unit;
• and,
• said second heat transfer medium passes through said heat exchanger (106) thereby releasing heat to the ambient surroundings.
