Title
(EN) LEAK DETECTING DEVICE AND LEAK DETECTING SYSTEM
(FR) DISPOSITIF DE DÉTECTION DE FUITE ET SYSTÈME DE DÉTECTION DE FUITE
(JA) 漏洩検知装置及び漏洩検知システム
Abstract
(EN)
This leak detecting device for detecting a refrigerant leak from an air conditioner in an air conditioned space which is air conditioned by means of the air conditioner is characterized by being provided with: a leak detecting unit for detecting a refrigerant leak; a communication unit which, if the leak detecting unit has detected a refrigerant leak, transmits notification information indicating that a leak has been detected, to an external device by way of a communication network; and a power supply unit which is turned on and off independently of an electricity supply to the air conditioner, and which supplies electricity to the leak detecting device.
