PURPOSE:To ensure quiet air conditioning securing the amount of air without causing any trouble on a ceiling back arrangement by disposing in series successively an air filter, an auxiliary fan, a body fan, and a heat exchanger from an air suction side to an air blow-off side it a casing. CONSTITUTION:One end of a cylindrical easing 1 with rectangular cross section is used as an air suction side 2, and the other and is used as an air blot-off side 3. There are disposed in the casing 1 an air filter 4, an auxiliary fan 5, an air fan 6, and a heat exchanger 7 from the air suction side 2 to the air blow-off side 3 successively in series. The main fan 6 has a suction inlet 10 at the center of a fan casing 9, and has a blow-off outlet 11 at the end of the fan casing 9, and the main fan 6 directs the blow-off outlet 11 toward the side of the heat exchanger 7. The auxiliary fan 5 has, liked in the main fan 6, a suction inlet 13 at the center of the far casing 12 and a blow-off outlet 14 at the end of the fan casing 12, and the auxiliary fan 5 directs the blow-off outltet 14 toward the main fan 6. |
