PROBLEM TO BE SOLVED: To provide an air conditioner to uniformalize an air supply volume in the lateral direction of an air outlet and enable suppression of the generation of noise. SOLUTION: A size between the front of a fan rotor 4 and a protrusion 6 of a front nose 5 situated nearmost to the front is represented by a and a size between the back of the fan rotor 4 and the front of a rear nose 7 is represented by b. When the sizes a and b are small, an air volume is increased to a high value and a noise sound generally becomes loud. Further, when the sizes a and b are large, an air volume is decreased to a low value. Accordingly, the sectional shape is the direction of the fan rotor 4 of the front nose 5 is gradually changed, the side, where a fin pitch is coarse, of an indoor heat exchanger 3 is increased in the size a and the side, where the fin pitch is fine, thereof is decreased in the size a. This constitution enables uniformity in a lateral direction of an air flow of supply air through an air supply passage 9 and the air outlet 10. |
