Since the heat exchanger 90 is installed at each location, inspection, cleaning, and replacement of each device can be easily performed when necessary.

The internal air supply unit 20 is located on one side of the enclosure 10 and supplies indoor air (return air, RA) to the interior of the enclosure 10.

As shown in FIGS. 1 and 2, the inner supply unit 20 includes a damper (no reference numeral) of a predetermined size installed on one upper surface of the enclosure 10, and a damper installed on one inner side of the enclosure 10. It includes a blower (no reference numeral) that allows indoor air to flow into the interior.

It includes a blower (no reference numeral) that ensures that the air is supplied into the room through the damper.

The exhaust unit 40 is configured to exhaust air introduced into the enclosure 10 to the outdoors (Exhaust Air, EA).

In this exhaust unit 40, a damper is installed on one side of the enclosure 10 between the internal supply unit 20 and the air supply unit 30, and by adjusting the opening amount of the damper, the air inside the enclosure 10 is released to the outside. The discharged flow rate is controlled.

The outside air supply unit 50 supplies outdoor air (Outside Air, OA) to the inside of the enclosure 10.

In this outdoor air supply unit 50, a damper is installed on one side of the enclosure 10 between the air supply unit 30 and the exhaust unit 40, and by adjusting the opening amount of the damper, outdoor air flows into the enclosure 100. The incoming flow rate is controlled.

It includes a porous plate 62 in which two through holes are formed.

At this time, the perforated plate 62 may be attached to one side of the damper 61 and be formed integrally with the damper 61, or alternatively, it may be installed at a predetermined distance from the damper 61, and in this case, it may be installed in the receiving space. It can be installed in a size corresponding to the cross-sectional size of the receiving space (S) so that the air can be dispersed overall based on the cross-sectional area of (S).

In addition, the size of the through hole formed in the perforated plate so that the air can be distributed may be formed differently depending on the location. For example, it is located in the center and formed at a position through which the air passing through the damper 61 can pass directly. The size of the through hole may be relatively smaller than the size of the through hole formed on the periphery.

That is, the size of the through hole may gradually increase from the center of the perforated plate 62 to the periphery, and when a certain amount of air is supplied to pass through the perforated plate 62, the air Due to the size of the through hole, there is a difference in the speed at which air passes, and as a result, the air passing through the center damper 61 does not pass directly through the center toward the electrostatic precipitator 70, but through the perforated plate 62. It is naturally distributed and passes through the circumference.

The electric dust collector 70 is installed on the receiving space (S) between the flow distribution device 60 and the air supply unit 30 and removes fine dust in the air supplied toward the air supply unit 30.

It may be composed of a PE coating layer (C) of a predetermined thickness coated on.

And at one end of the carbon base layer (B), a voltage application unit (A) is provided to apply power to the carbon base layer (B). This voltage application unit (A) is partially coated with the PE coating layer (C). It may be formed by omitting it, or it may be formed by partially removing the PE coating layer (C).

On the other hand, when the carbon base layer (B) is formed as a whole to match the width of the dust collection plate (72A'), an arc occurs between surrounding metal parts such as an adjacent support plate (not shown) that secures the dust collection plate (72A'), causing a fire. There is a risk that this may occur, and therefore, the present invention provides an uncoated portion where carbon is not coated at both ends along the upper and lower length in accordance with the location where adjacent components such as a support plate are installed in order to maintain a predetermined gap with adjacent metal components. (H) is formed, which structurally prevents arcing between the carbon film (72A") and surrounding metal parts.

Above, it is shown and explained that only the carbon film 72A" is attached to the dust collection plate 72A'. However, unlike this, a carbon base layer (not shown) is formed to cover the surface of the dust collection plate 72A', and then the carbon film 72A" is attached to the dust collection plate 72A'. It can be modified so that a PE coating is formed to cover the base layer.

In addition, a plurality of dust collection modules (72A) are assembled through a square-shaped mounting frame (72B), and are mounted on the mounting frame (72C) and a module fixture (72D) installed on the side of the mounting frame (72C). 72C) and the dust collection module 72A can be configured to be separately assembled.

Through the configuration of the dust collection unit 72 as described above, even if foreign substances in the air are attached to connect the dust collection plates 72A', the PE coating layer C of the carbon film 72A" structurally prevents electricity from flowing, causing sparks, arcs, etc. occurrence is prevented, and as a result, the installation interval between the dust collection plate (72A') and parts can be placed closer than before, and since the dust collection unit 72 is configured in module units through the dust collection module (72A), it can be partially replaced when necessary. becomes possible.

Above, it was shown and explained that the carbon film (72A") is attached and installed on the dust collection plate (72A'), but unlike this, the carbon film (72") was changed to serve as a dust collection plate instead of the dust collection plate (72A'). It can be configured.

It can be composed of a flexible tube that naturally contracts and expands.

In addition, the high-pressure washing unit 81 may be located on the downstream side with respect to the dust collection unit 72, and the suction unit 82 may be located on the upstream side with respect to the dust collection unit 72, through which the high-pressure washing unit 81 ) The dust collected in the dust collection unit 72 is separated by the high-pressure air discharged from the dust collection unit 72, and then during the process of being sucked out through the suction unit 82, the dust passes through the dust collection unit 72 and flows into the air supply unit 30. This is structurally prevented.

Meanwhile, the high-pressure washing unit 81 and the suction unit 82 are installed to be movable in the horizontal or vertical direction, and then moved to one side when the dry washing device 80 is not in operation so as not to impede the flow of air. Preferably, for this purpose, first and second square-shaped frames (F1, F2) are installed on both sides upstream and downstream of the dust collection plate 72, and a high-pressure washing unit is installed in these first and second frames (F1, F2). After (81) and the suction part (82) are installed respectively, the high pressure washing part (81) and the suction part (82) are moved in a horizontal or vertical direction along a horizontal or vertical rail (no reference numeral) through the drive motor (M). It can be installed movably.
