Air conditioner

Abstract

An air conditioner 1 is disclosed as an air conditioner configured to condition air by connecting an indoor unit 2 including a first heat exchanger 11 in which a refrigerant exchanging heat with room air flows to an outdoor unit 3 including a second heat exchanger 24 in which a refrigerant exchanging heat with outdoor air flows. The first heat exchanger 11 includes a first heat transfer tube 11a1 made of aluminum or aluminum alloy, and the second heat exchanger 24 includes a second heat transfer tube 24a made of aluminum or aluminum alloy. A first sacrificial layer 45a is formed on an outer circumferential surface of the first heat transfer tube 11a1, and a second sacrificial layer 35 is formed on an outer circumferential surface of the second heat transfer tube 24a. The maximum thickness to of the second sacrificial layer 35 is larger than the sacrificial layer ti1 of the first sacrificial layer 45a. This suppresses corrosion of the heat transfer tube of the outdoor unit.
