Title (EN) VOLUMETRIC EXPANSION MACHINE FOR A RANKINE CYCLE, AND CONTROL METHOD
(FR) MACHINE DE DETENTE VOLUMETRIQUE POUR CYCLE DE RANKINE, ET PROCEDE DE COMMANDE
Abstract:
(EN) The present invention concerns a volumetric expansion machine for a Rankine cycle, comprising a temperature sensor integrated into an expansion zone (316) comprising at least one cavity, in which movable means are arranged to drive a drive shaft (313), and a pressure sensor arranged downstream from the expansion zone (316), said sensors delivering an electric signal used by a computer controlling the state of said bypass valve (315) controlling the circulation of fluid in a bypass channel formed between a high-pressure inlet zone (314) for a pressurised working fluid (308) connected to the inlet port and a low-pressure exhaust zone (317) comprising the transmission between the movable means and the drive shaft (313) and connected to the exhaust port.
(FR) La présente invention concerne une machine de détente volumétrique pour cycle de Rankine, comprenant un capteur de température intégré dans une zone d'expansion (316) comprenant au moins une cavité, dans laquelle des moyens mobiles sont disposés pour entraîner un arbre moteur (313), et un capteur de pression disposé en aval de la zone d'expansion (316), lesdits capteurs délivrant un signal électrique exploité par un calculateur commandant l'état de ladite vanne de dérivation (315) commandant la circulation de fluide dans un canal de dérivation formé entre une zone d'admission (314) à haute pression d'un fluide de travail (308) sous pression raccordée à l'orifice d'admission et une zone d'échappement à basse pression (317) comprenant la transmission entre les moyens mobiles et l'arbre moteur (313) et raccordée à l'orifice d'échappement.
