Title:
REFRIGERANT LEAK MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/244798
Kind Code:
A1
Abstract:
When operation of a refrigeration cycle device is stopped over a long period of time, it is difficult to check for the presence/absence of refrigerant leaks. A refrigerant leak management system (1) comprises a timer (20) and a control unit (100). The timer (20) counts the duration of a period of time in which operation of a refrigeration cycle device (10) is stopped. The control unit (100) determines whether or not the operation stop period of the refrigeration cycle device (10) is longer than a predetermined first period. Upon determining that the operation stop period of the refrigeration cycle device (10) is longer than the first period, the control unit (100) causes the refrigeration cycle device (10) to operate or provides notification to a manager of the refrigeration cycle device (10).
