Abstract
An air-conditioning apparatus includes: an outdoor unit including a compressor that compresses and discharges refrigerant to a refrigerant circuit; an indoor unit including a load-side heat exchanger that causes heat exchange to be performed between air in an air-conditioned space and a heat medium subjected to heat exchange with the refrigerant; a flow rate detection unit that detects a flow rate of the heat medium; and an alarm unit provided in the indoor unit. The alarm unit includes a determination unit and an abnormality alarm unit. The determination unit determines whether an abnormality occurs in the indoor unit or not based on the flow rate detected by the flow rate detection unit. The abnormality alarm unit outputs an alarm when the determination unit determines that the abnormality occurs in the indoor unit.
