Title
(EN) IMPROVED ORGANIC RANKINE CYCLE DECOMPRESSION HEAT ENGINE
(FR) MOTEUR THERMIQUE À DÉCOMPRESSION À CYCLE DE RANKINE ORGANIQUE AMÉLIORÉ
Abstract
(EN) An improved heat engine includes an organic refrigerant having a boiling point below -35°C; a heat source having a temperature of less than 82°C; a heat sink; a sealed, closed-loop for the organic refrigerant, the closed-loop having both a high- pressure zone which absorbs heat from the heat source, and a low-pressure zone which transfers heat to the heat sink; a positive displacement decompressor providing a pressure gradient through which the organic refrigerant in its gaseous phase flows continuously from the high-pressure zone to the low-pressure zone, the decompressor extracting mechanical energy from the pressure gradient; and a positive displacement hydraulic pump, which provides continuous flow of the organic refrigrerant in its liquid phase from said low-pressure zone to said high-pressure zone, said hydraulic pump and said decompressor maintaining a pressure differential between the two zones of between about 20-42 bar.
(FR) L'invention concerne un moteur thermique amélioré qui comprend un réfrigérant organique ayant un point d'ébullition inférieur à -35°C; une source de chaleur ayant une température inférieure à 82°C; un dissipateur thermique; une boucle fermée étanche pour le réfrigérant organique, la boucle fermée ayant à la fois une zone haute pression qui absorbe la chaleur provenant de la source de chaleur, et une zone basse pression qui transfère la chaleur vers le dissipateur thermique; un décompresseur à déplacement positif produisant un gradient de pression à travers lequel le réfrigérant organique dans sa phase gazeuse s'écoule en continu à partir de la zone haute pression vers la zone basse pression, le décompresseur fournissant une extraction d'énergie mécanique à partir du gradient de pression; et une pompe hydraulique à déplacement positif, qui produit un écoulement continu du réfrigérant organique dans sa phase liquide de ladite zone basse pression à ladite zone haute pression, ladite pompe hydraulique et ledit décompresseur maintenant un différentiel de pression entre les deux zones compris entre environ 20 et 42 bars.
