(FR) SYSTÈME DE RÉCUPÉRATION DE CHALEUR D'UN MOTEUR À COMBUSTION INTERNE
Abstract:
(DE) Abwärmerückgewinnungssystem einer Brennkraftmaschine (5), wobei das Abwärmerückgewinnungssystem einen Arbeitsfluidkreislauf (1) mit einer Fluidpumpe (14), mit zumindest zwei in jeweils einem Fluidzweig (15a, 15b) des Arbeitsfluidkreislaufs (1) angeordneten Wärmetauschern (2a, 2b), einer Expansionsmaschine (11) und einem Kondensator (12) aufweist. Erfindungsgemäß wird ein Abwärmerückgewinnungssystem bereitgestellt, bei dem die Einstellung der jedem Fluidzweig (15a, 15b) zuzumessenden Menge Q1 und Q2 des Arbeitsfluids verbessert ist. Erreicht wird dies dadurch, dass die Fluidpumpe (14) zumindest zwei oszillierende Verdränge (20a, 20b) aufweist, und dass jeder Verdränger (20a, 20b) mit einem Fluidzweig (15a, 15b) zusammenwirkt.
(EN) The invention relates to a waste-heat recovery system of an internal combustion engine (5), wherein the waste-heat recovery system has a working fluid circuit (1), which has: a fluid pump (14), at least two heat exchangers (2a, 2b) arranged in respective fluid branches (15a, 15b) of the working fluid circuit (1), an expansion machine (11), and a condenser (12). According to the invention, a waste-heat recovery system is provided, in the case of which the adjustment of the amount Q1 and Q2 of the working fluid to be metered to each fluid branch (15a, 15b) is improved. This is achieved in that the fluid pump (14) has at least two oscillating displacing elements (20a, 20b) and that each displacement element (20a, 20b) interacts with one fluid branch (15a, 15b).
(FR) Système de récupération de chaleur d'un moteur à combustion interne (5), comprenant un circuit de fluide de travail (1) comprenant une pompe à fluide (14), au moins deux échangeurs thermiques (2a, 2b) disposés respectivement sur une branche de circulation de fluide (15a, 15b) du circuit de fluide de travail (1), une machine de détente (11) et un condenseur (12). L'invention a pour objet de fournir un système de récupération de chaleur permettant d'améliorer le réglage de la quantité Q1 et de la quantité Q2 du fluide de travail à fournir à chacune des branches de circulation de fluide (15a, 15b). Pour ce faire, la pompe à fluide (14) comprend au moins deux organes de refoulement (20a, 20b), et chaque organe de refoulement (20a, 20b) coopère avec une branche de circulation de fluide (15a, 15b).
