    • The invention relates to a cryogenic refrigeration device intended to transfer heat from a cold source (15) to a hot source (1) via a working fluid flowing through a closed working circuit (200) including the following portions in series, namely: a portion for the substantially isothermal compression of the fluid, a portion for the substantially isobaric cooling of the fluid, a portion for the substantially isothermal expansion of the fluid, and a portion for the substantially isobaric heating of the fluid. The compression portion of the working circuit (200) includes at least two compressors (7, 5, 3) disposed in series and the expansion portion of the working circuit (200) includes at least one expansion turbine (9, 11, 13), said compressors (7, 5, 3) and expansion turbine(s) (9, 11, 13) being driven by at least one high-speed motor (70) including an output shaft. One end of the output shaft supports and rotates, by means of direct coupling, a first compressor (7, 5, 3), while the other end of the output shaft supports and rotates, by means of direct coupling, a second compressor (7, 5, 3) or an expansion turbine (9, 11, 13).
    • 本发明涉及一种低温冷冻装置,其旨在经由流经闭合工作回路(200)的工作流体将热量从冷源(15)传递到热源(1),该工作流体包括以下部分,即:一部分 用于流体的基本等温压缩,用于流体的基本上等压冷却的部分,用于流体的基本上等温膨胀的部分以及用于流体的基本上等压的加热的部分。 工作回路(200)的压缩部分包括至少两个串联设置的压缩机(7,5,3),并且工作回路(200)的膨胀部分包括至少一个膨胀涡轮机(9,11,13) 所述压缩机(7,5,3)和膨胀涡轮(9,11,13)由包括输出轴的至少一个高速电机(70)驱动。 输出轴的一端通过直接联接支撑和旋转第一压缩机(7,5,3),而输出轴的另一端通过直接联接支撑和旋转第二压缩机(7) ,5,3)或膨胀涡轮机(9,11,13)。
