Title (EN) CRYOGENIC REFRIGERATION DEVICE
(FR) DISPOSITIF DE RÉFRIGÉRATION CRYOGÉNIQUE
Abstract:
(EN) Cryogenic refrigeration device comprising a working circuit intended to cool a working fluid circulating in the said circuit, the working circuit comprising, arranged in series in a loop: a compression portion (3), a cooling portion (5, 6, 22, 23, 24, 26, 27), a portion with valve(s) (9), an expansion portion (10, 25, 28) and a reheating portion, in order to subject the working fluid to a recuperative working cycle comprising compression, then cooling, then expansion and then reheating to prepare for a new cycle, wherein the compression portion comprises at least one compressor (3, 20, 21) having a linear piston driven by a linear motor (1), the expansion proportion comprises at least one expander (10, 25, 28) with a linear piston, the portion with valve(s) comprises at least one regulating valve (9) linearly actuated by a linear motor and controlled in order to supply or extract the working fluid from the at least one expansion piston.
(FR) Dispositif de réfrigération cryogénique comprenant un circuit de travail destiné à refroidir un fluide de travail circulant dans ledit circuit, le circuit de travail comprenant, disposés en série au sein d'une boucle: une portion de compression (3), une portion (5, 6, 22, 23, 24, 26, 27) de refroidissement, une portion à vanne(s) (9), une portion de détente (10, 25, 28) et une portion de réchauffement, pour soumettre le fluide de travail à une cycle de travail de type récupératif comprenant une compression puis un refroidissement puis une détente puis un réchauffement en vue d'un nouveau cycle, dans lequel, la portion de compression comprend au moins un compresseur (3, 20, 21) à piston linéaire entraîné par un moteur (1) linéaire, la portion de détente comprend au moins un détenteur (10, 25, 28) à piston linéaire, la portion à vanne(s) comprend au moins une vanne (9) de régulation de type linéaire actionnée par un moteur linéaire et pilotée pour alimenter ou extraire le fluide de travail du au moins un détendeur à piston.
