Abstract
A refrigerant leakage determination system includes a refrigerant circuit including a compressor, a condenser, an expansion mechanism, and an evaporator. The system performs a first determination, and a second determination. The first determination determines that refrigerant has leaked from the refrigerant circuit, by using a first state amount of refrigerant as a determination index, the first state amount including at least one of an outlet temperature of the condenser, a suction temperature of the compressor, and a discharge temperature of the compressor. The second determination determines that refrigerant has leaked from the refrigerant circuit, based on information different from the first state amount.
