Abstract:
1. An air conditioner comprising: a blower for introducing a gas that flows into the air conditioner from an intake port, into a blowoff port; a heat exchanger for exchanging heat between the gas and a refrigerant, the heat exchanger being disposed on the intake side of the blower and including a first heat exchanger and a second heat exchanger that are divided; heat exchanger tubes disposed in the heat exchanger, the heat exchanger tubes being substantially perpendicularly inserted into a plurality of fins, the heat exchanger tubes arranged in parallel with each other with a predetermined spacing along the direction of the rotational axis of the blower so as to form rows along the longitudinal direction of the fins, and being connected to each other along the gas flow direction in a plurality of rows, to thereby form refrigerant channels between a refrigerant inlet and a refrigerant outlet; and a branch pipe that is connected to a connection portion of the first heat exchanger in series between the refrigerant inlet and the refrigerant outlet, one branch of the branch pipe connected to the first heat exchanger and another branch of the branch pipe connected directly to the second heat exchanger, the branch pipe partially increases or decreases the number of paths in the refrigerant channels formed by the heat exchanger tubes, wherein the refrigerant flowing through each of a plurality of the refrigerant channels passing through paths mutually different in at least one portion between the refrigerant inlet and the refrigerant outlet, flows along one direction from a windward-side row to a leeward-side row, or from the leeward-side row to the windward-side row in the gas flow direction, in sequence between rows.
