A regenerative refrigeration cycle apparatus includes a refrigeration cycle circuit which is constructed by connecting a compressor, a four-way valve, an indoor heat exchanger, an expansion valve, and an outdoor heat exchanger. A regenerative unit for accumulating heat is arranged between the discharge side of the compressor and the four-way valve, and first and second heat exchangers are arranged in the regenerative unit together with a regenerative material. In a regenerating operation mode of the refrigeration cycle circuit, part of the refrigerant discharged from the compressor flows through the first heat exchanger, the indoor heat exchanger, and the outdoor heat exchanger, while the remaining part of the refrigerant flows through the second heat exchanger and the outdoor heat exchanger. The refrigerant discharged from the compressor is condensed in both the first and second heat exchangers, thereby heating the regenerative material.
