Air-conditioning apparatus

An air-conditioning apparatus comprising:

• a refrigerant circuit including a compressor, a first refrigerant flow switching device, a plurality of intermediate heat exchangers, a first expansion device, and a heat-source-side heat exchanger, through all of which a refrigerant circulates and all of which in combination form a refrigeration cycle;
• and
• a heat medium circuit including the plurality of intermediate heat exchangers, a pump, and a plurality of use-side heat exchangers, through all of which a heat medium circulates,
• wherein the air-conditioning apparatus further comprises
• a heat medium energy storage that is connected to the heat medium circuit and configured to store the heat medium;
• and
• an intra-storage heat exchanger that is connected to the refrigerant circuit and configured to heat or cool the heat medium in the heat medium energy storage by using the heat-source-side refrigerant supplied thereto,
• wherein the heat medium that is heated in the heat medium energy storage and is stored with heating energy in the heat medium energy storage is transported to any of the use-side heat exchangers that have been requested to perform heating operations, or
• the heat medium that is cooled in the heat medium energy storage and is stored with cooling energy in the heat medium energy storage is transported to any of the use-side heat exchangers that have been requested to perform cooling operations.
