Abstract
A refrigerant leakage notifying device includes a refrigerant sensor, a determination unit, a notification unit, and an output unit. The refrigerant sensor detects a refrigerant and outputs a detection signal according to a detection result. The determination unit receives the detection signal outputted from the refrigerant sensor and determines leakage of the refrigerant in accordance with the detection signal received. The notification unit notifies leakage of the refrigerant with at least one of sound and light in a case in which the determination unit has determined that the refrigerant is leaking. The output unit is provided separately from the refrigerant sensor. The output unit outputs a test signal to the determination unit. The test signal is a signal that the determination unit has determined that the refrigerant is leaking in a case in which the determination unit receives the signal.
