Abstract:
A refrigeration apparatus includes a refrigerant circuit including: a compressor, a radiator, an expansion mechanism, and an evaporator. The refrigerant circuit encloses a refrigerant that contains a fluorinated hydrocarbon that causes a disproportionation reaction. The refrigerant circuit further includes: a discharged refrigerant recovery receiver that is connected to a path between a discharge side of the compressor and a gas side of the radiator through a discharged refrigerant branch pipe; and a discharged refrigerant relief mechanism that is disposed in the discharged refrigerant branch pipe and that connects the discharge side of the compressor with the discharged refrigerant recovery receiver when the refrigerant on the discharge side of the compressor satisfies a predetermined condition. The predetermined condition includes at least one of a first condition under which the refrigerant does not yet cause the disproportionation reaction and a second condition under which the refrigerant causes the disproportionation reaction.
