Title (EN) ENGINE FOR ELECTRICAL RECOVERY
(FR) MOTEUR DESTINÉ À UNE RÉCUPÉRATION ÉLECTRIQUE
(JA) 電気回収エンジン
Abstract:
(EN) Disclosed is an engine for electrical recovery characterized in that one Stirling engine and another Stirling engine are unitized by being coupled to each other, using a heat exchanger (50) comprised of one gas passage (51A) which communicates with an expansion space (22A) of one displacer piston (20A), another gas passage (51B) which communicates with an expansion space (22B) of the other displacer piston (20B), and a heat medium passage (52) which heats the gas passage (51A) and the gas passage (51B). In the engine for electrical recovery, even a low-temperature exhaust heat of around 200°C which has been exhausted from a flue of a factory can be efficiently converted into electric energy by a heat exchanger for a low-temperature exhaust heat having a sufficient heat-transfer performance.
(FR) L'invention concerne un moteur destiné à une récupération électrique, caractérisé en ce qu'un moteur Stirling et un autre moteur Stirling sont réunis en étant couplés l'un à l'autre, à l'aide d'un échangeur thermique (50) constitué d'un premier passage de gaz (51A) qui communique avec un espace de dilatation (22A) d'un premier piston de déplacement (20A), d'un autre passage de gaz (51B) qui communique avec un espace de dilatation (22B) de l'autre piston de déplacement (20B) et d'un passage de fluide de chauffage (52) qui chauffe le passage de gaz (51A) et le passage de gaz (51B). Dans le moteur destiné à la récupération électrique, même un rejet thermique basse température d'environ 200 °C qui a été évacué à partir d'un conduit d'une usine peut être converti efficacement en énergie électrique par un échangeur thermique afin de générer un rejet thermique basse température présentant une performance de transfert thermique suffisante.
(JA)  本発明の電気回収エンジンは、一方のディスプレーサピストン20Aの膨張空間22Aと連通する一方のガス通路51Aと、他方のディスプレーサピストン20Bの膨張空間22Bと連通する他方のガス通路51Bと、一方のガス通路51A及び他方のガス通路51Bを加熱する熱媒体通路52とを形成する熱交換器50によって、一方のスターリングエンジンと他方のスターリングエンジンとを連結してユニット化したことを特徴とし、十分な伝熱性能を有する低温排熱用熱交換器により、工場などの煙道から排出される200℃域の低温排熱からでも効率よく電気エネルギーに変換できる電気回収エンジンを提供する。
