Air-conditioning apparatus
An air-conditioning apparatus includes a refrigerant circuit, an indoor unit, an indoor air-sending device, a refrigerant detection device which detects refrigerant in an air-conditioning target space, and a controller which sets each of a normal control mode and a rarefying control mode. In the normal control mode, an operation is performed in an operation mode set according to an air-conditioning load, and in the rarefying control mode, the indoor air-sending device is controlled at a rarefying rotation speed which is a higher rotation speed than that in the normal control mode. The controller includes a refrigerant determination unit which determines, based on the result of detection by the refrigerant detection device, whether leakage of refrigerant occurs or not, a control mode determining unit which determines, in the case where the leakage determination unit determines that leakage of refrigerant occurs, the rarefying control mode as a control mode to be set, and an operation control unit which controls the indoor air-sending device in accordance with the control mode set by the control mode setting unit.
