The air supply fan unit is located at the inlet side of the air and is used when the length of the outside air introduction duct is at least 10 m or more.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1, a dust collecting unit 3 provided with a ventilating fan unit 1, a counterflow type heat exchanging unit 2 and a UV sterilizing lamp 3r coated with a photocatalyst (TiO ₂ ) is connected to an air supply fan unit 4 (1a) of the ventilation fan unit (1) and the heat exchange unit (2) are installed in the housing (5) in parallel with the air supply passage (1n) The casing 5 of the ventilation fan unit and the housing 5 of the heat exchange unit 2 are connected to each other by a support rod r And is suspended vertically to the ceiling concrete beam cb.

As shown in Figs. 1 and 2, the ventilation fan unit 1 is provided with a ventilation fan 1f which is driven by a motor 1m inside a case 1a in which a noise preventing member 1s is incorporated And an exhaust diffuser 1d for discharging indoor air to the outside is provided in the central portion of the diffuser plate 1c adhered to the ceiling u in association with the exhaust flow path 1u and external air is supplied around the intake diffuser 1d And an air supply diffuser 1b to be introduced into the room is provided in association with the air supply flow path 1n.

As shown in Fig. 3, the counterflow type heat exchange unit 2 provided in the housing 5 has a plurality of square-shaped heat exchange plates 2f formed with an airflow passage 2a made of a material excellent in corrosion resistance and thermal conductivity, And the air flow paths 2a of the heat exchange unit 2 alternate into the air supply flow path 2n and the air flow path 2u. The counterflow type heat exchanger is characterized in that the heat exchange surface of the heat exchange plate 2f is wide and the air flow path 2a is longer than the tetragonal type heat exchanger, and the recovery rate of waste heat by heat exchange is higher.

The air supply passage 2n of the countercurrent heat exchange unit 2 is associated with the air supply duct D1 and the exhaust passage 2u of the counterflow type heat exchange unit 2 is associated with the exhaust pipe D2, Exhaust and air supply of the ventilation fan unit 1 are respectively associated with the air supply duct D1 and the exhaust duct D2 communicating with the unit 1 so that both the exhaust flow path 2u and the air supply flow path 2n A heat exchange function is performed between the exhaust and the supply air by the heat exchange plate 2f. At the time of heating, the waste heat recovered from the exhaust by the heat exchange unit 2 is supplied to the room through the air supply. During the cooling, the heat recovered by the heat exchange unit 2 is discharged to the outside through the exhaust.

Therefore, it is possible to maintain the equilibrium in the room temperature during heating or cooling.

As shown in FIG. 4, the dust collecting unit 3 includes a pre-filter (not shown), and the first dust collecting unit 3A and the second dust collecting unit 3B are coupled to each other inside the case 3c.

5, the first dust collecting section 3A of the dust collecting unit 3 is provided with an ionization section IONIZER of a cell constituted by alternately arranging a ground plate 3e and a tungsten wire 3w in a frame 3f It accomplishes. When a high voltage (DC 7 ~ 8kv) is supplied to the tungsten wire (3w), a strong electrostatic field is formed between the tungsten wire (3w) and the dust collecting plate (3e), causing the fine dust and various pollutants in the air to be positively ionized And then flows into the second dust collecting part 3B.

The second dust collecting unit 3B of the dust collecting unit 3 is alternately arranged in the frame 3t in such a manner that the repulsive electrode plate 3p (positive electrode) and the ground plate 3n (negative electrode) And the dust and contaminants ionized by the first dust collecting unit 3A pass through between the positive and negative electrode plates of the second dust collecting unit 3B and are adsorbed on the negative electrode plate to be filtered.

The unfiltered prefilter is mounted in front of the dust collecting unit to remove large dust such as hair, animal hair, etc., and to clean the filter and replace the filter.

As shown in Figure 6, the oscillating UV germicidal lamp (3r) with (3v) is that the photocatalyst (TiO ₂₎ is applied to the lamp envelope (3m) and the UV germicidal lamp (3r) are of the dust collection unit (3) Dust is provided on the side of the outlet port through which clean air filtered out flows.

Generally, when a rated voltage is applied to the UV sterilizing lamp 3r, a strong ultraviolet ray is emitted to sterilize various microorganisms floating in the air. At this time, the catalytic action of the photocatalyst promotes the activity of ultraviolet rays to increase the decomposition ability of the organic material. Therefore, microorganisms are effectively sterilized.

The air supply fan unit 4 is located at the suction port side of the dust collecting unit 3 and is one of air suction means for introducing outside air into the room.

The air supply fan unit 4 is used when the length of the outside air introduction duct is at least 10 m or more. This is because when the length of the outside air introduction duct is short, the outside air can be sucked sufficiently by the operation of the fan 1f of the ventilation fan unit 1. [

When the ventilation fan 1f is operated by the motor 1m of the ventilation fan unit 1, the air supply passage 1n becomes negative pressure and the exhaust passage 1u becomes a positive pressure . Therefore, the outside air flows into the air supply mechanism OA by the negative pressure generated by the operation of the ventilation fan 1f, so that the outside air flows into the air supply fan unit 4 and the dust collection unit 4 regardless of whether the air supply fan unit 4 is in operation or not. The air supply diffuser 1b of the diffuser plate 1c via the air supply passage 2 of the counterflow type heat exchange unit 2 and the air supply duct 1n of the ventilation fan unit 1 through the air supply duct 1n, So that the air is largely convected in the room.

On the other hand, the room air is sucked into the exhaust diffuser 1d provided at the center of the diffuser plate 1c, and is passed through the exhaust passage 2u of the counterflow type heat exchange unit 2 via the exhaust passage 1u and the exhaust pipe D2 And is discharged to the outside exhaust port (EA).

In this way, various dirt and pollutants existing in the outside air are filtered by the dust collecting unit 3 in the course of the outside air being introduced into the room. The filtration process is a process in which the dust of large particles is first filtered by the pre-filter as described above and the dust is removed by the ionization action of the ground plate 3e and the tungsten wire 3w in the first dust collecting section 3A of the dust collecting unit 3 The pollutant is ionized and then filtered by the dust collecting action of the rebound plate 3p and the ground plate 3n of the second dust collection unit 3B. The dust-filtered air kills various microorganisms floating in the air due to the strong ultraviolet rays emitted from the UV sterilization lamp 3r and the catalytic action of the photocatalyst.

The clean air filtered by dust and pollutants by the dust collecting unit 3 passes through the air supply passage 2n of the adjacent counterflow type heat exchange unit 2 by the heat exchange action of the heat exchange plate 2f And collects the waste heat from the exhaust passing through the exhaust passage 2u. At this time, the outdoor temperature recovered from the waste heat by the heat exchange unit is not constant depending on the season, but is higher than about 5 ° C to 10 ° C as compared with the ambient temperature before heat exchange.

Accordingly, since the outside air supplied to the room contains a certain amount of heat and flows into the room, the room temperature rises to room temperature. Therefore, the outside air is introduced into the room by the ventilation fan unit 1, Even during the process, the temperature of the room air is kept in equilibrium.

Also, since the air supplied from the outside is clean air sterilized by the dust collecting unit 3, it is beneficial to the health of the human body, so that the body health can be safely protected from the pollution environment.

The ventilation fan unit 1, the counterflow type heat exchange unit 2, the dust collecting unit 3, and the air supply fan unit 4 of the ventilation system can be applied without changing the inherent form or function of the existing device The multi-convective ventilation device can be economically produced at a lower cost.
