Abstract:
Provided is a refrigerant leakage detection device whereby the implementation of inspections can be confirmed. The refrigerant leakage detection device comprises: a detection circuit that detects output from a refrigerant sensor; a control means that executes, on the basis of the output from the detection circuit, a normal mode in which the presence or absence of a refrigerant leak is determined, and an inspection mode in which an inspection is made as to whether or not the refrigerant sensor is operating normally; and a storage means that, in the inspection mode, stores the date that an inspection was performed on the refrigerant sensor and stores the result of the inspection of the refrigerant sensor.
