Explaining the schematic configuration, a heat exchanger 8 folded in two is arranged so as to surround the entire region in the suction direction (160 ° to 200 °) when viewed from the center of the cross flow fan 2. Regarding the general flow, the air sucked from the suction grill 5 passes through the air filter 6 and the heat exchanger 8 and is sucked into the cross flow fan 2, around which the air formed by the rear guider 3 and the stabilizer 4 is formed. And is discharged from the outlet 7.
