The overall configuration of a specific embodiment of the cyclone ventilator duct air conditioning equipment according to the present invention is shown in FIGS. 2 and 3.

As can be seen from this, the cyclone ventilator duct air conditioning facility according to the present invention is a duct air conditioning facility installed in a duct through which outdoor air passes through an underground shelter,

Absorbs or reflects electromagnetic waves penetrating through ducts connected to the outside to block them and to allow air to pass through, formed of multiple layers of metal panels that are grounded and grounded, and block electromagnetic waves in the form of a network in which a plurality of honeycomb structure holes are formed with part 200;

A cyclone blade 300 that rotates spirally with the air passing through the electromagnetic wave blocking unit 200 and generates accelerated wind;

Dispersion blades 400 for sucking and dispersing the wind accelerated by the cyclone blades 300;

A control motor 500 rotating the cyclone blade 300;

A housing part 100 surrounding the cyclone blade 300, the dispersion blade 400, and the control motor 500;

A NBC filter unit 600 may be configured to filter contaminants from the wind dispersed by the dispersion blades 400.

If this is explained in more detail for each component, the cyclone ventilator duct air conditioning facility according to the present invention is compact and conventional air conditioning so that it can be directly installed in the duct of the duct air conditioning facility configured in a protection system such as an underground shelter, air defense shelter, or protection chamber. The amount of air purification and ventilation can be increased compared to facilities, noise is minimized, and energy is saved to improve efficiency.

To this end, the cyclone blade 300 of the cyclone ventilator duct air conditioning equipment of the present invention, as illustrated in FIGS. 3 and 4, has a long and hollow conical body 310,

A plurality of wing parts 320 bent in a continuous curve from the top to the bottom of the side surface of the body 310 and protruding from the side surface;

Ventilation parts 330 through which wind passes are formed between the plurality of wing parts 320 of the side parts close to the bottom part of the body 310,

The sum of the cross-sectional areas of the ventilation parts 330 is greater than or equal to the cross-sectional area of the duct connected to the outside.

In addition, the dispersion blades 400 are installed closer to the control motor 500 than the cyclone blades 300, and more blades than the cyclone blades 300 are equally arranged,

The wind spirally turned and accelerated by the cyclone blade 300 is sucked in from the vent 330 of the cyclone blade 300 and blown in the axial direction.

Accordingly, the cyclone blade 300 sucks in a large amount of outside air due to its characteristic shape and the configuration of the wing part 320, turns in a spiral, and generates a strong whirlwind that accelerates, so it sucks in more outside air more effectively than conventional ventilators. Before the strong whirlwind generated by the cyclone blade 300 strikes the inner wall of the housing part 100 surrounding the cyclone blade 300, the dispersion blade ( 400) sucks in the whirlwind from the vent 330 formed on the side surface of the body 310 of the cyclone blade 300, disperses it with more wings of the dispersion blade 400 than the cyclone blade 300, and blows it in the axial direction. It is possible to minimize noise generation while increasing the airflow amount, and since the dispersed wind can be evenly purified in the NBC filter unit 600, the replacement life of the NBC filter unit 600 is extended and a large amount of air is stably purified. will become possible.

Here, the sum of the cross-sectional areas of the ventilation parts 330 formed between the wing parts 320 of the cyclone blade 300 is configured to be greater than or equal to the cross-sectional area of the duct connected to the outside, so that simultaneous intake through the cross-sectional area of the duct connected to the outside Since the whirlwind generated by the cyclone blades 300 in an amount greater than that of air passes through the ventilation units 330, positive pressure is generated to increase the suction power of external air.

In addition, the control motor 500 can rotate the cyclone blade 300 and the dispersion blade 400 together, and the rotational force of the dispersion blade 400 riding a strong whirlwind generated by the cyclone blade 300 is When the torque is greater than the rotational force of the control motor 500, energy can be saved by towing the rotation of the cyclone blade 300, and the shaft 510 of the control motor 500 is connected to the dispersion blade 400 through a clutch. The dispersing blades 400 can be selectively separated, so that only the cyclone blades 300 are rotated step by step to rotate spirally and generate a strong whirlwind that is accelerated. Since wind can be dispersed, only the cyclone blades 300 can be rotated with little energy, so energy can be saved or air can be efficiently cleaned with little energy.

In addition, as shown in FIGS. 2 and 3, the housing part 100 includes an input duct connection part 110 connected to a duct through which outside air passes,

A blocking unit housing 120 for fixing the electromagnetic wave blocking unit 200 so that the air sucked through the input duct connection unit 110 passes through the electromagnetic wave blocking unit 200;

A filter housing 140 for fixing the NBC filter unit 600 so that the wind dispersed by the dispersion blades 400 passes through the NBC filter unit 600;

An output duct connection unit 150 connected to an indoor duct may be configured to supply air that has passed through the NBC filter unit 600 to the room.

Here, the electromagnetic wave blocking unit 200 fastened to the blocking unit housing 120 is made of a metal having excellent electrical conductivity, and is a metal mesh panel having a plurality of honeycomb-shaped through holes having a diameter smaller than the amplitude of electromagnetic waves. Since it can be composed of multiple layers, it is possible to block electromagnetic waves while passing air, and the blocking unit housing 120 and the filter housing 140 have a cross-sectional area greater than that of the input duct connection unit 110 and the output duct connection unit 150, respectively. Since it is configured large, even if a large amount of external air is introduced by the cyclone blade 300, it can be effectively achieved by minimizing the bottleneck and stabilizing the internal pressure during the whirlwind generation and air purification action inside the housing unit 100,

The blade housing 130 has a larger cross-sectional area than the blocking housing 120 or the filter housing 140, and is configured to be twice or longer in length, and spirally rotated and accelerated by the cyclone blade 300 within the blade housing 130 Generation of a strong whirlwind is facilitated, noise and vibration can be minimized, it is formed in a cylindrical shape, and reverse flow is blocked by the circular protruding band 131 protruding inside the blade housing 130, so that air flows into the filter housing ( 140) may be prevented from interfering.

In addition, a filter insertion hole 141 formed under the filter housing 140,

A filter stand 610 that seals the filter insertion port 141 and is fixed to the filter housing 140;

A protrusion 142 formed on the filter housing 140 and engaged with the filter stand 610 by elasticity of the elastic body;

A button 143 may be configured to move the protrusion 142 by applying force against the elasticity of the elastic body so that the NBC filter unit 600 can be separated from the filter housing 140 together with the filter stand 610. Even if the cyclone ventilator duct air conditioning equipment according to the present invention is installed in a duct installed high above most people's heads, the NBC filter unit 600 moves downward by gravity from the lower part of the filter housing 140 only by pressing the button 143. ) Since the NBC filter is separated and free-falling, not only can it be easily replaced, but also when a new NBC filter is fastened, if the NBC filter is pressed against the filter insertion port 141 of the filter housing 140 and pushed up from the bottom to the top, the elastic body Since the filter insertion port 141 is sealed by the filter support 610 while being elastically fixed by the protrusion 142 that is caught and fixed with the filter support 610, not only the filter replacement is facilitated, but also the filter insertion port 141 As it is sealed, it is possible to fundamentally block the problem that unpurified air leaks and pollutes the internal air or generates noise.

It purifies the outside air and sterilizes the purified air with an air ionization sterilizer. It can purify the air by blocking, adsorbing or removing pollutants, odors, fine dust, harmful gases and biochemical hazardous substances contained in the air. There is.

As such, since the NBC filter of the NBC filter unit 600 in the filter housing 140 adsorbs and purifies harmful gases or radioactive fallout, it is not desirable to be exposed to the room or come into contact with the human body during replacement, and it can be replaced safely and harmlessly. It is sealed and fastened to surround the filter insertion port 141 of the filter housing 140 to accommodate the contaminated filter of the NBC filter unit 600 that is dropped by the operation of the button 143 of the filter housing 140 without human contact or exposure to the room.
