Abstract

See full text

A refrigeration cycle apparatus includes a refrigerant circuit in which a compressor, a first heat exchanger, a first expansion device, a second expansion device, and a second heat exchanger are connected by refrigerant pipes and through which refrigerant circulates, an accumulator provided to the refrigerant circuit, formed to store liquid refrigerant, and from which gas refrigerant is caused to be sucked into the compressor, a liquid-level sensing device provided to the accumulator and sensing a liquid level of the liquid refrigerant stored in the accumulator, and a controller performs, in a case in which the liquid level sensed by the liquid-level sensing device is higher than a threshold, a limiting operation of reducing an amount of suction of the gas refrigerant that is sucked from the accumulator into the compressor and, in a case in which the liquid level is lower than or equal to the threshold, a normal operation.
