PURPOSE:To permit the regulation of the blow-off direction, range, amount of air and the like of conditioned air arbitrarily, by a method wherein a plurality of fans are arranged in the relative positions of vertical direction while the fan casings of respective fans are attached so that the directions of the delivery ports of respective fans are changeable and pivotable independently. CONSTITUTION:The title indoor unit is provided with the suction port 3 of indoor air, the blow-off ports 4a, 4b, 4c of conditioned air and the like while a heat exchanger 5 is provided behind the suction port 3. The fan 8a of a centrifugal fan, driven by a motor 9a and rotated in a fan casing 15a, is provided at the upper part of the back side of the heat exchanger 5 while the fan 8b is provided at the lower part of the back side of the heat exchanger 5 in the same manner. The inside of a main body casing 2 is partitioned by bulkheads 13a, 13b: the casing 15a of the upper centrifugal fan is pivotally attached to the bulkhead 13a and the casing 15b of the lower centrifugal fan is pivotably attached to the bulkhead 13b. An air passage 19 for guiding air into a blow-off port 4e at the lower part of the front surface of the main body case 2 and a damper 20 are provided at the lower part of the main body casing 2. |
