Abstract
(EN)
A system comprising a refrigeration engine (132) and regulator (250, 350, 450, 550, 650) positioned within a housing (144, 244), the regulator (250, 350, 450, 550, 650) controlling fuel to the engine through a fuel line (354), a lock-off valve connected to the regulator (250, 350, 450, 550, 650) to shut off fuel supply through the regulator (250, 350, 450, 550, 650), a controller operably connected to the lock-off valve and/or the regulator (250, 350, 450, 550, 650), a guide (462, 562) positioned within the housing (144, 244) and proximate to the refrigeration engine (132), the regulator (250, 350, 450, 550, 650), and/or the fuel line (354) to direct gases leaking from the refrigeration engine (132), regulator (250, 350, 450, 550, 650), and/or at least one fuel line (354), and a methane sensor (566, 666A) positioned within the guide (462, 562) to detect the presence of methane within the guide (462, 562) that is directed by the guide (462, 562), the methane sensor (566, 666A) in communication with the controller and configured to transmit a signal to the controller when methane is detected by the methane sensor (566, 666A). The controller performs a safety action when the signal from the methane sensor (566, 666A) is received.

L'invention concerne un système comprenant un moteur de réfrigération (132) et un régulateur (250, 350, 450, 550, 650) positionné à l'intérieur d'un boîtier (144, 244). Le régulateur (250, 350, 450, 550, 650) commande le carburant vers le moteur par l'intermédiaire d'une conduite de carburant (354). Le système comprend également une soupape de blocage reliée au régulateur (250, 350, 450, 550, 650) pour arrêter l'alimentation en carburant à travers le régulateur (250, 350, 450, 550, 650), un dispositif de commande connecté de manière fonctionnelle à la soupape de blocage et/ou au régulateur (250, 350, 450, 550, 650), un guide (462, 562) positionné à l'intérieur du boîtier (144, 244) et à proximité du moteur de réfrigération (132), du régulateur (250, 350, 450, 550, 650), et/ou de la conduite de carburant (354) pour diriger les gaz s'échappant du moteur de réfrigération (132), du régulateur (250, 350, 450, 550, 650) et/ou de l'au moins conduite de carburant (354), et un capteur de méthane (566, 666A) positionné à l'intérieur du guide (462, 562) pour détecter la présence de méthane dans le guide (462, 562) qui est dirigé par le guide (462, 562). Le capteur de méthane (566, 666A) est en communication avec le dispositif de commande et est configuré pour transmettre un signal au dispositif de commande lorsque le méthane est détecté par le capteur de méthane (566, 666A). Le dispositif de commande effectue une action de sécurité lorsque le signal provenant du capteur de méthane (566, 666A) est reçu.
