PURPOSE: An air circulation apparatus for a residential and commercial complex is provided to minimize a noise when supplying or discharging air by absorbing the noise through separate sound-absorbing pipes. CONSTITUTION: An air circulation apparatus for a residential and commercial complex comprises a bracket(100), a motor housing(200), a motor(300), a plurality of guide blades(400), a plurality of sound-absorbing pipes(500), a bellmouth(600), and a nozzle tube(700). The motor housing is attached to the bracket installed on the ceiling of an underground parking lot. The motor with a plurality of impellers(310) circulating the internal air current of the underground parking lot is installed inside of the motor housing. The guide blade discharges the air current while uniformly distributing the air current. The sound-absorbing pipes absorb the noise which is produced when the air current circulates. The bellmouth helps smooth collection of the air current. The nozzle tube helps quick discharge of the air current.
