Abstract
This invention provides a refrigeration and air conditioning system and a method for inspecting such a system that enables highly accurate inspection. [Solution] The refrigeration and air conditioning system comprises a refrigeration and air conditioning device 1, an alarm 71 that outputs an alarm sound when a refrigerant leak from the refrigeration and air conditioning device 1 is detected, a sound collector 72 positioned to collect the alarm sound from the alarm, and a control device 2 that performs inspections of the alarm 71 and the sound collector 72 based on the sound collected by the sound collector 72 during periods when the alarm 71 is not emitting an alarm, and the sound collected by the sound collector 72 during periods when the alarm 71 is emitting an alarm.
