PURPOSE: A ductless air inlet for a building is provided to improve degree of freedom of a nozzle body and prevent vibration noise of a chamber. CONSTITUTION: A ductless air inlet for a building comprises a noise reduction unit(10), a drive unit(20), and a mixing injection unit(30). The noise reduction unit has plural partition walls(12) alternately from an inlet formed in the rear of a box-shaped exhaust body(100). Drive unit is communicated with the noise reduction unit and a fan(21) is mounted to the drive unit, centering on a hinge(22). The missing injection unit has a nozzle body(40) controlled at multi-angles. The nozzle body is communicated with the drive unit and is installed in front of the exhaust body. Thus, multi-directional jet from the nozzle body is possible and the degree of freedom is improved, and smooth jet of air is performed.
