Abstract: A regenerative air-conditioning apparatus includes a thermal energy storage unit, first and second valve devices for switching a flow direction of a refrigerant compressed in a compressor, a first branch part disposed on an outlet-side of the compressor, the first branch dividing the refrigerant compressed in the compressor to flow into first and second valve devices or the thermal energy storage unit, a first storage unit connection tube extending from the first branch part to the thermal energy storage unit, a condensed refrigerant tube extending from an outdoor heat exchanger to an indoor heat exchanger, a second storage unit connection tube extending from the thermal energy storage unit to the condensed refrigerant tube, and a first expansion device disposed in the first storage unit connection tube to selectively restrict a flow of the refrigerant from the first branch part to the thermal energy storage unit.
