Air-conditioning apparatus and air-conditioning method

An air-conditioning apparatus comprising:

• a heat source device that includes a refrigerant cycle circulating a refrigerant;
• an air-conditioning unit configured to perform a heating operation and a cooling operation by exchanging heat between the refrigerant and indoor air;
• a hot water supply unit that includes a hot water storage tank and configured to perform a hot water supply operation by heating with the refrigerant;
• and
• control circuitry configured to perform a first alternate operation of alternately performing the heating operation and the hot water supply operation when a heating request and a hot water supply request are received at the same time, and to perform a second alternate operation of alternately performing the cooling operation and the hot water supply operation when a cooling request and the hot water supply request are received at the same time, wherein
• the control circuitry is configured to perform control to make a first continuous operation time of the hot water supply operation in the first alternate operation different from a second continuous operation time of the hot water supply operation in the second alternate operation.
