Abstract
An air-conditioning apparatus includes a refrigerant circuit, a heat medium circuit, and a controller. In the refrigerant circuit, a compressor, a heat-source-side heat exchanger, an expansion unit, and a load-side heat exchanger are connected by refrigerant pipes, and refrigerant flows. The heat-source-side heat exchanger causes heat exchange to be performed between the refrigerant and a heat-source heat medium. The load-side heat exchanger causes heat exchange to be performed between the refrigerant and a load heat medium, and refrigerant flows. In the heat medium circuit, a flow control valve that regulates the flow rate of the heat-source heat medium and the heat-source-side heat exchanger are connected by a heat medium pipe, and the heat-source heat medium flows. The controller includes a storage unit that stores data indicating a defined maximum flow rate and a defined minimum flow rate of the heat-source heat medium that flows in the heat medium circuit.
