Document Type and Number:
Japanese Patent JP7118248
Kind Code:
B2
Abstract:
A refrigeration apparatus (1) includes: a refrigerant circuit through which refrigerant circulates; a controller (100) to execute a plurality of refrigerant shortage sensing functions of sensing a shortage of an amount of the refrigerant; and an input device (110) through which an operation mode to be set is input into the controller (100). The operation mode includes: a first mode in which energy-saving performance is emphasized; and a second mode in which the refrigeration apparatus (1) is permitted to operate in a range in which reliability is ensured. In accordance with the operation mode set through the input device (110), the controller (100) determines which one of sensing results obtained by the refrigerant shortage sensing functions is enabled and which one of sensing results obtained by the refrigerant shortage sensing functions is disabled. When a sensing result determined to be enabled shows a refrigerant shortage, the controller (100) gives a notification about the refrigerant shortage.
