Abstract
When refrigerant gas leaks in an indoor unit, the leaked refrigerant gas locally accumulates in an area of the indoor space. This air conditioner includes an indoor unit having one or more outlets, and an outdoor unit connected to the indoor unit, wherein a flammable refrigerant or a mildly flammable refrigerant is used. The air conditioner includes a refrigerant gas sensor disposed in the indoor unit. When refrigerant gas is detected by the refrigerant gas sensor, a control is performed such that air is blown from the one or more outlets at a minimum air speed or higher, said minimum air speed being preset in accordance with the rated cooling capacity of the air conditioner.
