Abstract
(EN)
Disclosed are a precooling device for cryotherapy and a cryotherapy system. The precooling device comprises an air inlet interface (8), at least three gas through-flow branch paths, a single-stage compression self-cascading refrigeration system assembly (2), and a pressure regulating assembly (1), wherein the single-stage compression self-cascading refrigeration system assembly (2) comprises at least three stages of refrigeration cycle (200), each refrigeration cycle (200) can perform heat exchange with gas flowing through the corresponding gas through-flow branch path so as to precool the gas flowing through the corresponding gas through-flow branch path, the pressure regulating assembly (1) is used for controlling the pressure at a gas outlet end of the pressure regulating assembly (1), and the pressure at the gas outlet end of the pressure regulating assembly (1) is related to the current precooled gas through-flow branch path.

L'invention concerne un dispositif de pré-refroidissement pour cryothérapie et un système de cryothérapie. Le dispositif de pré-refroidissement comprend une interface d'entrée d'air (8), au moins trois voies de dérivation de flux de gaz, un ensemble de système de réfrigération en cascade à compression à étage unique (2), et un ensemble de régulation de pression (1). L'ensemble système de réfrigération en cascade à compression à étage unique (2) comprend au moins trois étages de cycle frigorifique (200) dont chacun peut effectuer un échange de chaleur avec le gaz s'écoulant à travers le trajet de dérivation de flux de gaz correspondant de façon à pré-refroidir le gaz s'écoulant à travers le trajet de dérivation de flux de gaz correspondant, l'ensemble de régulation de pression (1) est utilisé pour contrôler la pression au niveau d'une extrémité de sortie de gaz de l'ensemble de régulation de pression (1), et la pression au niveau de l'extrémité de sortie de gaz de l'ensemble de régulation de pression (1) est liée au trajet de dérivation de flux de gaz pré-refroidi actuel.
