<p>An indoor unit for an air conditioning device, having arranged inside main casings (31, 32): an indoor heat exchanger (15) through which a flammable refrigerant flows; an indoor fan (18) that sucks in air via the indoor heat exchanger (15) and blows out same from an upper outlet (32a) and a lower outlet (32b) provided in the main casings (31, 32); and a refrigerant sensor (60) for detecting leakage of the flammable refrigerant. An indoor control device (200) controls the indoor fan (18), a flap (34), and a shutter (50) and, if refrigerant leakage is detected by the refrigerant sensor (60), operates the indoor fan (18) for a pre-set agitation operation time and jets out outlet air from the upper outlet (32a) and the lower outlet (32b), to the indoor floor side. As a result, an indoor unit for an air conditioner is provided that disperses refrigerant pooled on the floor side indoors and reduces risk associated with leakage of flammable refrigerant.</p> |
