Abstract (en)

[origin: EP3279582A1] There is provided an indoor unit 1 of an air conditioning apparatus in which an conditioned air heat-exchanged by a heat exchanger 3 using a slightly flammable refrigerant or a flammable refrigerant having specific gravity higher than that of air is blown out from a blowout port 5 by an indoor fan 6. The indoor unit 1 is provided with a refrigerant sensor 8 for detecting leakage of the refrigerant and a blowout port opening/closing mechanism capable of closing a part of the blowout port 5. When the refrigerant sensor 8 detects leakage of the refrigerant, the indoor fan 6 is driven in a state in which a part of the blowout port 5 is closed by the blowout port opening/closing mechanism.
