| description | A refrigerant leakage determination device (60) includes a calculator (66) and a determination unit (67). The calculator (66) calculates a deviation degree of a refrigerant circuit (20) from a normal state based on data related to operation of a refrigeration apparatus (1). The determination unit (67) determines refrigerant leakage or estimates refrigerant leakage occurrence time based on a calculation result of the calculator (66). The calculator (66) calculates first and second index values respectively from data related to operation of the refrigeration apparatus (1) in a first period and a second period that differs in length from the first period and calculates the deviation degree of the refrigerant circuit (20) from the normal state based on the first and second index values. The determination unit (67) determines refrigerant leakage or estimates refrigerant leakage occurrence time based on the deviation degree of the refrigerant circuit (20) from the normal state. |
