An air conditioner including a distributor configured to distribute a fluid to a heat exchanger. The distributor comprises a main pipe; a partition defining a plurality of distribution paths in the main pipe; a first branched pipe inserted into the main pipe as much as first length, linked to a first distribution path of the plurality of distribution paths, connected to a first portion of the heat exchanger; and a second branched pipe inserted into the main pipe as much as second length different from the first length, linked to the first distribution path, connected to a second portion of the heat exchanger. A flow velocity of air exchanging heat at the first portion of the heat exchanger is faster than a flow velocity of air exchanging heat at the second portion of the heat exchanger. The first length is shorter than the second length.
