<p>An air conditioner comprises an air intake port (4) for introducing the air in a room into the casing of an indoor unit (1), an air discharge port (5) formed at the lower part of the casing, an air flow path (6) for communicating the air intake port (4) with the air discharge port (5), an indoor heat exchanger (9) that has a refrigerant tube bent in a plurality of stages and rows and that is disposed curvedly along the inner surface of the casing so as to face the air intake port (4), and cross flow fan (7) disposed between the indoor heat exchanger (9) in the air flow path (6) and the air discharge port (5). The air flow path (6) includes a forward guide section (6a) which guides the air to the forward lower side and is gradually increased in its flow passage area toward the downstream side. The sum of the lengths of the upper wall (6b) and the lower wall (6c) of the air flow path (6) closer to the downstream side than the cross flow fan (7) is set to 3.5 times the diameter of the cross flow fan (7) or more.</p> |
