Abstract
Operation data of a refrigerant circuit is acquired after an initial refrigerant charge amount of refrigerant is charged in the refrigerant circuit and operation of the refrigerant circuit is started, an internal volume of a high-pressure pipeis computed from the obtained operation data and the initial refrigerant charge amount input in a input unit, a target refrigerant charge amount is computed from the computed internal volume of the high-pressure pipeand a standard operating state acquired in advance, the standard operating state being operation data of the refrigerant circuit when the refrigerant circuit is in a standard operating state that satisfies a preset condition, and an additional refrigerant charge amount is computed from the target refrigerant charge amount and the initial refrigerant charge amount.
