Classification: CPC F  Y | IPC F

Claim 1:
2. The air-conditioning apparatus of claim 1, wherein
the controller includes a storage unit configured to store data, and
the controller is configured to
store, as data in the storage unit, a relationship between the flow rate and the pressure of the heat medium in a path along which the heat medium flows, the relationship being obtained from the pump flow rate and pressures detected by the indoor-side pressure sensors associated with the respective flow rate control devices in the first operation, and
calculate flow rates of the heat medium that flows through the respective use-side heat exchangers from the pump flow rate, pressures detected by the indoor-side pressure sensors associated with the respective flow rate control devices, and a pressure detected by the pump inlet-side pressure sensor or the pump outlet-side pressure sensor in the second operation, based on the data regarding the relationship between the flow rate and pressure of the heat medium and stored in the storage unit.
