Abstract
A space in which an indoor unit is disposed has its corresponding refrigerant leakage sensor. A remote control for the indoor unit has its corresponding information output device for notifying the user of information visually and/or aurally. When the refrigerant leakage sensor detects a leakage of refrigerant, an alarm outputs a warning sound and a safety measure device is activated. Further, the information output device outputs guidance information for notifying the user action to be taken after the safety measure device takes the safety measure. After outputting the guidance information, the information output device stops outputting the guidance information in response to completion of the user action.
