Abstract: An air conditioner includes an outdoor unit, an indoor unit and a refrigerant circuit. The conditioner performs heating operation in which an indoor heat exchanger functions as a condenser for a refrigerant that is compressed by a compressor and an outdoor heat exchanger functions as an evaporator for a refrigerant that is condensed by the indoor heat exchanger. The conditioner includes a memory, and processing circuitry configured to estimate an amount of refrigerant that remains in the circuit by using an operating state quantity of the conditioner in the heating operation. The estimating includes a plurality of different estimation models that correspond to ranges of the amount of refrigerant that remains in the circuit. One of the estimation models uses, as the operating state quantity, a degree of supercooling of refrigerant at an outlet of the indoor heat exchanger.
