Abstract
An air-conditioning apparatus includes an outdoor unit and an indoor unit between which refrigerant is circulated. The indoor unit includes a body casing that forms an outer shell, a heat exchanger provided in the body casing, a drain pan provided below the heat exchanger, a water-level detecting unit that detects the level of condensate water that has flowed into the drain pan, and a refrigerant-gas detecting unit that is provided in the drain pan and at a higher level than the water-level detecting unit, and detects refrigerant gas that has leaked from the heat exchanger. The air-conditioning apparatus includes a controller that performs control to stop a cooling operation when the water-level detecting unit detects the condensate water that collects in the drain pan.
