Abstract
A refrigeration cycle device performs a heating operation and a defrosting operation. A refrigerant circulates in opposite directions in the defrosting operation and the heating operation. The refrigeration cycle device includes a compressor, a first heat exchanger and a second heat exchanger, a decompressor, and a flow path switch. In the heating operation, the refrigerant circulates in the order of the compressor, the first heat exchanger, the decompressor, and the second heat exchanger. In the defrosting operation, the refrigerant circulates in the order of the compressor, the second heat exchanger, the decompressor, and the first heat exchanger. The defrosting operation includes a first mode and a second mode. The opening of the decompressor is greater in the first mode than in the heating operation. The opening of the decompressor is less in the second mode than in the first mode.
