Hereinafter, a method and apparatus for controlling a supply air amount according to an indoor exhaust amount according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 13, the apparatus 10 for adjusting the amount of air supply according to the amount of indoor exhaust according to the present invention includes a main body 100, an air supply 200, a natural evaporation unit 300, and a control unit 400. ), and adjusts the amount of air supplied through the air supply unit 200 in conjunction with the exhaust amount of the exhaust unit 20 of the ventilation monitor 2 installed on the ceiling so that the air inside the building (1) can be exhausted. It is a device.

The body portion 100 is formed in a hexahedral shape through the bottom plate 110, the corner support 120 and the top plate 130, as shown in FIG. 2, and is light and excellent in strength by bonding carbon fibers to plastic.

The bottom plate 110 has a water tank 112 in which a certain amount of water is stored, and a discharge port 112a is formed in the center of the water tank 112 so as to communicate with the room.

Here, the water stored in the water tank 112 is supplied to the upper side to wet the moisture absorption filter 330 of the natural evaporation unit 300, and the hot air passes through the moisture absorption filter 330 to evaporate the water, thereby cooling the temperature of the air. In this state, the cold air is discharged to the outside.

On the other hand, the discharge port (112a) is exemplified as being a lower discharge type formed on the bottom plate 110, but is not limited thereto, and an upper discharge type formed on the upper plate 130, or between the corner support 120 and the corner support 120 It is possible to implement a change to the side discharge type formed in the. In this way, depending on the location of the discharge port 112a, the building 1 is connected to the building 1 through the connector 11 and communicated.

Moreover, the bottom plate 110 further includes a water supply valve 114, a pump 116 and a drain valve 118.

The water supply valve 114 is a valve that supplies water into the water tank 112.

The pump 116 is provided to supply water stored in the water tank 112 to the distribution unit 332. To this end, hoses 116a provided in the pump 116 are connected to the distribution parts 332 in all directions.

Furthermore, the pump 116 sends water to the distribution unit 332 at every set time (for example, 3 hours) under the control of the control unit 400.

The drain valve 118 is a valve that drains used water every set time (for example, 4 hours). In this way, the drain valve 118 is opened at every set time to drain and supply new water, thereby blocking the growth of microorganisms.

On the other hand, although not shown in the drawing, the water tank 112 is provided with a sensor that detects the water level to stop the operation of the water supply valve 114 when it reaches the set water level.

The corner support 120 is installed at each corner of the opposite surface of the bottom plate 110 and the top plate 130.

The upper plate 130 is supported on the upper portion of the corner support 120.

The air supply unit 200 is composed of a motor 210 and a fan 220, as shown in FIG. 2, and a motor 210 is installed in the discharge port 112a of the bottom plate 110 to install a fan 220 installed on the drive shaft. ) Rotates to inhale the outside air strongly.

At this time, the air sucked through the air supply unit 200 evaporates the water of the moisture absorption filter 330 in the process of passing through the moisture absorption filter 330 of the natural evaporation unit 300 moistened at room temperature in the summer. After the air is cooled by the vaporized latent heat of evaporation and flows into the main body 100, cold air is blown through the upper discharge port 112a.

On the other hand, the fan 220, as shown in Figs. 5 to 7, the body part 210, the impeller part 220, and the air guide part 230 are integrally made of special carbon fiber to improve durability and prevent corrosion. It works.

The body portion 210 is formed with a coupling hole 222 so that the drive shaft of the motor 210 is coupled.

In this case, the impeller part 220 is coupled to the sliding groove formed on the outer circumferential surface of the body part 210 with the coupling part formed at the end thereof, and the coupling direction is the rotation direction of the fan 220 so that it is not separated during the rotation process of the fan 220 It is preferable that it is in the opposite direction. Moreover, although not shown in the drawing, a hemispherical groove is formed at the end of the sliding groove to prevent separation of the detachable impeller unit 220, and a spring and a sphere are sequentially inserted into the groove formed at the bottom end of the impeller unit 220 At the entrance of the groove, the sphere is supported so that it does not escape. In this way, while the sphere is pressed by the elastic force of the spring, it is possible to support the impeller 220 while the sphere is coupled to the hemispherical groove of the sliding groove.

The air induction part 230 protrudes from the front surface of the impeller part 220 at every set interval to induce the air to have a straightness. At this time, the air guide unit 230 is formed to correspond to the length according to the width of the impeller unit 220.

Furthermore, referring to FIG. 6, the angle θ of the air induction part 230 is preferably formed to have an obtuse angle based on an extension line extending from the body part 210 side.

Accordingly, the air induction unit 230 naturally blocks air that is diffused by centrifugal force when the fan 220 rotates, thereby inducing the air to have straightness.

In addition, as shown in FIG. 7, the air induction part 230 is formed to be inclined at both ends, and the opposite inclined ends are formed at the same height, so that the vulnerability of the edge portion can be eliminated.

In this way, the fan 220 can be applied to an evaporative cooler, etc., and interferes with the air diffused by centrifugal force when the fan 220 rotates through the air guide unit 230 provided radially in front of the impeller unit 220. Since the moving direction is made to have straightness, the straight distance is improved without a structure such as a separate duct, and the vacuum is relieved in the rotation process at the rear.

It is divided into dogs. Moreover, the number of divisions of the air induction unit 230-1 is not limited thereto and may be changed.

Meanwhile, the air guide unit 230-1 maintains a state in close contact with the front of the impeller unit 220-1 by the elastic force of the elastic member 236-1 while being rotatably supported by the support unit 232-1. It is done.

At this time, the elastic member (236-1) is a torsion spring, one end is supported by the angle limiting portion (234-1), the other end is supported by the air guide portion (230-1).

Moreover, the air induction part 230-1 has a bent part 230a-1 formed at the top, so that the bent part 230a-1 and the impeller part 220-1 rotate while the wind enters between the bent part 230a-1 and the impeller part 220-1 when the fan rotates. A space is formed through (230a-1).

In addition, an angle limiting unit 234-1 is provided inclined to limit the maximum rotation angle of the air guide unit 230-1 on the support unit 232-1.

Therefore, when the fan is not rotated, the air guide part 230-1 is in close contact with the impeller part 220-1, and the air guide part 230-1 is set up by the air diffused by centrifugal force as the fan rotates to limit the angle. When in close contact with the part 234-1, air is guided by the air guide part 230-1, and when the fan is stopped, the air guide part 230-1 becomes the impeller part 220 by the restoring force of the elastic member 236-1. It is in close contact with -1) to prevent damage to the air induction part 230-1.
