Abstract
An air-conditioning apparatus includes an indoor unit that cools or heats an air-conditioning target space; an outdoor unit that supplies heating energy or cooling energy to the indoor unit; a refrigerant shut-off unit that shuts off supply of refrigerant to the indoor unit; a refrigerant sensor that detects refrigerant leaking from the indoor unit; a space detector that detects information regarding a volume of a space where the indoor unit is installed; and a controller. The controller determines whether or not the space where the indoor unit is installed is a small space based on a detection result from the space detector, and energizes the refrigerant sensor when the space where the indoor unit is installed is the small space.
