An air conditioner comprising: a compressor; an outdoor condenser configured to condense refrigerant compressed by the compressor; a cooling expansion valve configured to decompress the refrigerant condensed by the outdoor condenser; an evaporator configured to evaporate the refrigerant decompressed by the cooling expansion valve by exchanging heat with indoor air, and to cool and dehumidify the indoor air; a cooling circuit connecting the compressor, the outdoor condenser, the cooling expansion valve, and the evaporator in that order; a reheat path that branches from a path connecting the compressor and the outdoor condenser in the cooling circuit, and is connected to a path connecting the cooling expansion valve and the evaporator; an indoor condenser configured to condense, in the reheat path, the refrigerant compressed by the compressor by exchanging heat with the indoor air cooled and dehumidified by the evaporator, and configured to heat the indoor air; a reheat expansion valve configured to decompress, in the reheat path, the refrigerant condensed by the indoor condenser; and a control apparatus configured to control opening degrees of the cooling expansion valve and the reheat expansion valve, characterized in that the control apparatus includes: a cooling control unit configured to adjust a degree of superheating of the refrigerant that has passed through the evaporator by adjusting a circulation amount of the refrigerant in the evaporator through control of the opening degree of the cooling expansion valve; and a reheat control unit configured to adjust a room temperature by adjusting a circulation amount of the refrigerant in the indoor condenser through control of the opening degree of the reheat expansion valve, and an upper limit of the opening degree of the reheat expansion valve controlled by the reheat control unit is set based on a ratio between a cooling capacity of the evaporator and a reheat capacity of the indoor condenser, the ratio being a fixed predetermined value and enabling the cooling expansion valve to adjust the degree of superheating. a compressor;
