Abstract
An air-conditioner which performs an appropriate control in the event of a leak of refrigerant. The air-conditioner includes a refrigerant circuit, a refrigerant leak sensor which senses a leak of refrigerant in the refrigerant circuit, an indoor fan which delivers air to the indoor heat exchanger, and an indoor control circuit which, upon sensing a leak of refrigerant by the refrigerant leak sensor, controls the indoor fan based on whether the refrigerant sealed in the refrigerant circuit is flammable.
