An air-conditioning apparatus 100 includes a refrigerant circuit A including a compressor 10, a first refrigerant flow switching device 11, a plurality of intermediate heat exchangers 25, a first expansion device 26, and a heat-source-side heat exchanger 12, through all of which a refrigerant circulates and all of which in combination form a refrigeration cycle; and a heat medium circuit B including the plurality of intermediate heat exchangers 25, a pump 31, and a plurality of use-side heat exchangers 35, through all of which a heat medium circulates. The air-conditioning apparatus further includes a heat medium energy storage 60 that is connected to the heat medium circuit B and stores the heat medium; and an intra-storage heat exchanger 25c that is connected to the refrigerant circuit A and heats or cools the heat medium in the heat medium energy storage 60 by using the heat-source-side refrigerant supplied thereto. The heat medium that is heated in the heat medium energy storage 60 and is stored with heating energy in the heat medium energy storage 60 is transported to any of the use-side heat exchangers 35 that have been requested to perform heating operations, or the heat medium that is cooled in the heat medium energy storage 60 and is stored with cooling energy in the heat medium energy storage 60 is transported to any of the use-side heat exchangers 35 that have been requested to perform cooling operations.
