Abstract
Provided is an inspection support system (100) for an alarm (6) of an air conditioning system (1) including a refrigerant leakage detection sensor (5) and the alarm (6), which issues an alarm sound when the refrigerant leakage detection sensor (5) detects refrigerant leakage. The inspection support system (100) comprises: a communication unit (10) that communicates with a terminal device (21) via a network (20) and that transmits an alarm start request, which is a signal for instructing the alarm (6) to issue an alarm sound, to the alarm (6) when a remote inspection start signal is received from the terminal device (21); a sound collection unit (11) that is installed in a space (8) to be air-conditioned and that collects a first environmental sound, which is a surrounding sound, after the communication unit (10) transmits the alarm start request to the alarm (6); and a sound determination unit (12) that determines an inspection result to be normal when it is determined that an alarm sound is contained in the first environmental sound collected by the sound collection unit (11), determines an inspection result to be abnormal when it is determined that an alarm sound is not contained in the first environmental sound, and transmits the inspection result to the terminal device (21).
