However, in the conventional air circulation apparatus, a vortex is generated due to the rotation of the air passing through the impeller, and the forward force is reduced.

This is because the vortex generated by the rotation of the air in the circular tube cancels the flow of air, and the resistance does not reach to a long distance.

In addition, in the conventional air circulation apparatus, since the number of revolutions of the impeller by the drive motor is fixed, there is a problem that the air volume can not be controlled.

In addition, in the conventional air circulation system, the taken-out airflow can not sufficiently reach the desired air-conditioning area, and the heat loss (staying in the upper part of the room and being lost to the roof) There is a disadvantage that the time must be kept long.

As a result, the conventional air circulation system needs to increase the equipment capacity, and it is almost impossible to control the airflow speed, the reaching distance, the air flow rate and the direction in accordance with each zone, so that even if the air conditioner and the heat source equipment are operated, It is impossible to obtain the cooling / heating temperature and the circulation air flow that are suitable for the heating and cooling system, resulting in enormous energy loss and financial loss due to facility investment.

The shear inlet pipe 200 is connected to one end of the fan joint pipe 100 and includes a driving motor 130 and an inlet tube 210 for promoting the flow of the airflow by the rotation of the impeller 120 A bellows ring 220 in the form of a trumpet is provided at the end side to which the airflow is introduced to form an expanding inlet.

At this time, the sound insulating member is further coupled to the inner circumference of the shear inlet pipe, thereby preventing the generation of noise due to the inflow and exhaust of the air stream.

The rear end exhaust pipe 300 is connected to the other end of the fan joint pipe 100 so as to form an exhaust pipe 310 through which the introduced airflow is directed toward a desired space, A venturi pipe 320 having a smaller diameter than the inlet side is formed.

In addition, the venturi pipe 320 is further provided with a draw-out branch pipe 330 having a sliding structure on its inner circumferential surface, so that the distance of the airflow to be injected can be increased.

That is, the diameter of the center portion of the fan joint pipe and the diameter of the inflow end are formed to be wider than the discharge end, so that the venturi pipe can discharge the airflow away.

At this time, the draw-out branch pipe is moved along the sliding groove 332 in the venturi pipe along the longitudinal direction while the conveying member 331 corresponds to the sliding groove 332.
