An air-conditioning apparatus can perform a heating and heat storage operation in which an indoor heat exchanger 12 and a heat storage heat exchanger 10 are each caused to function as a condenser, and heat source side heat exchangers 5A and 5B are each caused to function as an evaporator, and in which heat is stored in a heat storage material while a heating operation is being performed, a first heating and defrosting operation in which the heat source side heat exchanger 5A and the indoor heat exchanger 12 are each caused to function as a condenser, and the heat source side heat exchanger 5B and the heat storage heat exchanger 10 are each caused to function as an evaporator, and in which heat is transferred from the heat storage material and a defrosting operation of a heat source unit 100 is performed while a heating operation is being performed, and a second heating and defrosting operation in which the heat source side heat exchanger 5B and the indoor heat exchanger 12 are each caused to function as a condenser, and the heat source side heat exchanger 5A and the heat storage heat exchanger 10 are each caused to function as an evaporator, and in which heat is transferred from the heat storage material and a defrosting operation of a heat source unit 200 is performed while a heating operation is being performed. The first heating and defrosting operation and the second heating and defrosting operation are sequentially performed with the heating and heat storage operation in between. |
