Document Type and Number:
WIPO Patent Application WO/2020/208714
Kind Code:
A1
Abstract:
A refrigeration device (1) comprises: a refrigerant circuit in which a refrigerant circulates; a control device (100) that executes a plurality of refrigerant shortage detection functions that detect a shortage of the amount of the refrigerant; and an input device (110) that inputs an action mode set in the control device (100). The action mode includes: a first mode that emphasizes energy saving; and a second mode that allows the operation of the refrigeration device (1) for as long as reliability is ensured. The control device (100) determines which detection result of the plurality of refrigerant shortage detection functions is made valid and which detection result is made invalid according to the action mode set from the input device (110), and provides a notification of the refrigerant shortage in a case where a detection result that is made valid indicates a refrigerant shortage.
