Beschreibung
Zusammenfassung:	The present invention discloses a method and device for detecting a gas concentration by a refrigerator, and the refrigerator. The method comprises: acquiring a gas leakage amount St and a volume V of a kitchen, and detecting an opening angle α1 of a kitchen door and an opening angle α2 of a kitchen window; calculating a gas concentration Ct based on the V, α1, α2 and St; and activating, if the gas concentration Ct exceeds a minimum warning value, a gas emergency shut-off device to cut off a gas main switch, and activating a ventilation device of the kitchen. Compared with the prior art, the method of the present invention calculates the gas concentration in the kitchen by detecting the gas leakage amount, the size of the kitchen space, the opening angle of the kitchen door and the opening angle of the kitchen window, which allows to take different measures based on different gas concentrations.
