Distributor, heat exchanger unit and air conditioner

An air conditioner comprising:

• a distributor configured to distribute a fluid passing inside of the distributor;
• and
• a heat exchanger including a plurality of refrigerant pipes in which the fluid distributed by the distributor flows, the heat exchanger configured to exchange heat with air,
• wherein the distributor comprises:
• a main pipe;
• a partition defining a plurality of distribution paths separated from each other in the main pipe, the plurality of distribution paths including a first distribution path and a second distribution path being different from the first distribution path;
• a first branched pipe inserted into the first distribution path as much as a first insertion length, the first branched pipe connected to a first refrigerant pipe in a first portion of the heat exchanger;
• a second branched pipe inserted into the first distribution path as much as a second insertion length longer than the first insertion length, the second branched pipe connected to a second refrigerant pipe in a second portion of the heat exchanger;
• and
• a third branched pipe inserted into the second distribution path as much as the second insertion length of the second branched pipe inserted into the first distribution path, and
• wherein 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.
