Abstract
An object of the present invention is to provide an air-conditioner capable of ensuring safety when flammable refrigerant is used. An air-conditioner using flammable refrigerant includes ion-exchange resin having a sulfonic acid group or an ammonium group as a functional group and placed in a flow path of the refrigerant. An acid component of the refrigerant flowing in a refrigeration cycle reacts with the functional group according to operation of the air-conditioner to generate a first odor substance.
