(EN) GAS LEAK SENSING SYSTEM AND GAS LEAK SENSING METHOD
(FR) SYSTÈME DE DÉTECTION DE FUITE DE GAZ ET PROCÉDÉ DE DÉTECTION DE FUITE DE GAZ
要約
(EN) A gas leakage detection system includes: a closed chamber including an inlet port and an exhaust port and configured such that the closed chamber is ventilatable; piping through which liquefied gas or boil-off gas generated as a result of evaporation of the liquefied gas flows, the piping including a plurality of leakage-expected portions that are present in the closed chamber in a scattered manner; a first gas detector installed at the exhaust port; and at least two second gas detectors, each of which has a gas detection sensitivity lower than that of the first gas detector and is installed near at least two of the plurality of leakage-expected portions.
(FR) L'invention concerne un système de détection de fuite de gaz comprenant : une chambre fermée configurée de telle sorte qu'une ventilation est possible, la chambre fermée étant pourvue d'une ouverture d'alimentation en air et d'une ouverture d'évacuation d'air ; un tuyau à travers lequel s'écoule un gaz liquéfié ou un gaz d'évaporation obtenu par évaporation du gaz liquéfié, le tuyau possédant une pluralité d'emplacements de fuite probable dispersés à l'intérieur de la chambre fermée ; un premier capteur de gaz disposé dans l'ouverture d'évacuation d'air ; et au moins deux deuxièmes capteurs de gaz ayant une sensibilité au gaz inférieure à celle du premier capteur de gaz, les au moins deux deuxièmes capteurs de gaz étant respectivement disposés au voisinage d'au moins deux de la pluralité d'emplacements de fuite probable.
