発明の名称
(EN) GAS LEAK SENSING SYSTEM AND GAS LEAK SENSING METHOD
(ZH) 气体泄漏检测系统以及气体泄漏检测方法
要約
(EN) A gas leak sensing system comprises: an enclosed chamber configured such that ventilation is possible, the enclosed chamber being provided with an air supply opening and an air discharge opening; a pipe through which flows a liquefied gas or an evaporation gas obtained by evaporating the liquefied gas, the pipe having a plurality of leak expectation locations scattered within the enclosed chamber;a first gas sensor disposed in the air discharge opening; and at least two second gas sensors having lower sensitivity to gas than does the first gas sensor, the at least two second gas sensors beingdisposed in the vicinity of at least two of the plurality of leak expectation locations, respectively.
(ZH) 气体泄漏检测系统具备:密闭室,其构成为具备进气口以及排气口,能够进行换气;配管,其供液化气或该液化气气化后的蒸发气体流动,具有散布在密闭室内的多个泄漏假定部位;第1气体检测器,其设置于排气口;以及至少两个第2气体检测器,它们的气体检测灵敏度比第1气体检测器低,并且分别设置在多个泄漏假定部位中的至少两个泄漏假定部位的附近。
