The present invention relates to an air cleaning system using a ventilation unit, and more specifically, in the process of ventilating the indoor and outdoor air, the indoor and outdoor air is exchanged with each other, and if necessary, the indoor air is discharged by replacing the heat exchanger with a filter means. The present invention relates to an air cleaning system using a ventilation unit that is circulated back to a room after purification using a filter means.

The indoor air in which we live is polluted by various factors, and in order to have a pleasant life, it is essential to ventilate the indoor air and bring the outdoor air into the room.

In particular, in places where many people stay in a narrow space such as an office or a vehicle, ventilation should be frequently provided. In this case, the general ventilation is to open a window or use a fan.

Since the ventilation method by opening the window of the above-described ventilation method is a ventilation by the natural convection, the polluted air is discharged to the outside and the outdoor air is not introduced into the room is low, which does not have a great effect on the ventilation. have.

In addition, the method of ventilating using a fan has a problem that fresh outdoor air does not flow because only indoor polluted air is forced to be discharged to the outside.

To solve this problem, a conventional ventilation unit developed for forcibly introducing fresh outdoor air into a room and forcibly discharging contaminated outdoor air to an outdoor place is illustrated in FIGS. 1 and 2.

As shown in FIGS. 1 and 2, in the conventional ventilation unit, contaminated indoor air is exhausted to the outside through the heat exchanger 1 and the indoor air fan 2, and the outdoor air is exchanged to the heat exchanger 1.

That is, in summer, the temperature is lowered by heat exchange with the low-temperature indoor air as the outdoor air flows into the room, and in the winter, the indoor air is high as the outdoor air flows into the room. Heat exchange with air causes the temperature to rise.

However, the conventional ventilation unit configured as described above has a problem in that although heat can be maintained to some extent through indoor heat exchange, heat loss still occurs. In particular, when a concrete building is newly constructed and harmful components that cause sick house syndrome are detected for a certain period of time, the conventional ventilation unit as described above has an effect of removing harmful components by ventilating indoor and outdoor air. Although the loss problem can be compensated to some extent, when a certain period of time and no harmful components that cause sick house syndrome, etc. are no longer detected, there is a disadvantage that the heat loss problem can not be compensated.

5 of the accompanying drawings is an exploded perspective view showing a state in which the filter unit is provided in the air cleaning system using the ventilation unit according to an embodiment of the present invention, Figure 6 is a plan view showing a flow of air in FIG. 5 and 6 illustrate a state in which the filter unit is replaced in place of the heat exchanger in FIGS. 3 and 4.

As shown in FIG. 5 and FIG. 6, the filter unit 80 cleans the bet moved through the bet transfer path 12 and purifies the outside air moved through the outside air transfer path 11, and a carbon filter. (81), the first prefilter 82, the nonwoven fabric filter 83, the medium filter 84, the hepa filter 85, the anion nonwoven fabric 86, and the like are interviewed with each other.

At this time, the surface of each filter constituting the filter unit 80 is installed to be located on the bet conveying passage 12 is made to be purified while passing through the bet conveying passage 12.

On the other hand, one side of the filter portion 80 exposed to the inlet side of the outside air conveying passage 11 is bonded to the second pre-filter 87 for primarily purifying the outside air, is exposed to the outlet side of the outside air conveying passage (11) The other side of the filter unit 80 is closed by the closing membrane 88 so that air does not communicate.

Therefore, the outside air flowing into the outside air transfer passage 11 through the outside air inlet 16 does not move directly to the outlet side of the outside air transfer passage 11 through the filter unit 80 at the inlet side of the outside air transfer passage 11. After passing through the filter unit 80, the outlet side of the inside transfer path 12 and the intermediate damper 52 to be described later is moved to the outlet side of the outside air transfer path (11).

Hereinafter, the operation of the air cleaning system using the ventilation unit according to an embodiment of the present invention configured as described above will be described in detail with reference to FIGS. 4 and 6.

First, during the period of detecting the harmful components for building a new concrete building and generating a sick house syndrome, as shown in FIG. 4, the heat exchanger 40 may be detachably installed at an intersection of the outside air passage 11 and the inside air passage 12. do.

In this case, by operating the buttons of the controller 60, the outdoor air fan 30 installed at the outlet side of the outdoor air transfer passage 11 and the indoor air fan 31 installed at the outlet side of the internal air transfer passage 12 are respectively. Operate, the external damper 50 is fully open and the intermediate damper 52 is fully closed.

When the air fan 30, 31, the external air damper 50, and the intermediate damper 52 are operated in this way, the fresh outdoor air is opened through the air inlet duct 20 by the suction force of the outdoor air fan 30. After being introduced into the outside air transfer passage 11, the temperature increases or decreases through heat exchange with the indoor air while passing through the heat exchanger 40, and then indoors through the outdoor air fan 30 and the outdoor air discharge duct 21. Is discharged.

At the same time, the indoor air contaminated is introduced into the air transfer path 12 of the frame 10 through the air inlet duct 22 by the suction force of the indoor air fan 31, and then exchanges heat with the outdoor air while passing through the heat exchanger. Then, it is discharged to the outside through the indoor air fan 31 and the air discharge duct 23.

As such, during the period when new components are being constructed and harmful components that cause sick house syndrome are detected, indoor indoor air can be contaminated and clean outdoor air can be introduced into the room to create a pleasant indoor environment. The heat loss can be reduced by performing heat exchange between the indoor air discharged to the outside and the outdoor air introduced into the room during the process.

On the other hand, when no more harmful components that cause sick house syndrome and the like in the room after a certain period of time is no longer detected by replacing the filter unit 80 instead of the heat exchanger 40 to clean the indoor air.

In this case, the outdoor air fan 30 is installed on the outlet side of the outdoor air transfer passage 11 by opening the external air damper 50 and the intermediate damper 52 in a state where the operation of the indoor air fan 31 is stopped first.

It is filtered again through the filters 81, 82, 83, 84, 85, 86, and is moved to the outlet side of the bet transfer passage 12, and then through the intermediate damper 52, the outside air transfer passage 11. It is transferred to the outlet side of the) and is supplied to the room through the outdoor air fan 30 and the outdoor air discharge duct (21).

At this time, the air flowing into the filter unit 80 through the second pre-filter 87 is primarily the respective filter (81) (82) (83) (84) (85) ( After entering between the 86, the closed membrane 88 passes through the filters 81, 82, 83, 84, 85, and 86 while the direction is bent toward the outlet of the bet transfer passage 12. .

As such, outdoor air is filtered again while passing through the filters 81, 82, 83, 84, 85, and 86. Some of the outdoor air may have a small number of filters to penetrate the filter, and some may be filtered out. Although the number of filters can be large, the filtration may be a lot, but since the outdoor air pollution is lower than the indoor air basically, it does not matter much in the number of filters passing through.

On the other hand, due to the suction force of the outdoor air fan 30 installed on the outlet side of the outdoor air transfer passage 11, not only the outdoor air but also the indoor air is formed in the frame 10 through the internal air intake duct 22, the internal air transfer passage 12 After being introduced to the inlet side of the filter unit 80 and filtered, the filtered air is mixed with the outdoor air at the outlet side of the bet transfer passage 12 and then the intermediate damper 52, the outdoor air fan 30 and the outside air The discharge duct 21 is supplied to the room again.

At this time, since the indoor air is more polluted than the outdoor air, the air is purified cleanly while passing through all the filters 81, 82, 83, 84, 85, and 86 constituting the filter unit 80. do.

For reference, in the process of circulating the purified outdoor air and indoor air as shown in FIG. 6, since the bet damper 51 is formed as a backflow prevention damper, external air does not flow through the bet discharge duct 23. .

As such, when a concrete building is newly constructed and a certain period of time is no longer detected, a toxic component that causes sick house syndrome, etc., is ventilated by circulating back to the room after purifying through the filter unit 80 without discharging the indoor air to the outside. It can prevent or minimize the heat loss problem that occurs during operation.

Meanwhile, when the oxygen generator 70 and the anion generator 90 are operated in the process of discharging air into the room by operating the outdoor air fan 30 installed at the outlet side of the outside air passage 11, the oxygen generator 70 Oxygen and negative ions generated from the negative ion generator 90 are mixed with outdoor air or indoor air and then introduced into the room.

As described above with reference to the accompanying drawings an air cleaning system using a ventilation unit according to a preferred embodiment of the present invention, the present invention is not limited to the embodiments and drawings described in detail herein, Various modifications may be made within the scope.

According to the air cleaning system using the present invention ventilation unit configured as described above, during the period when the harmful components that cause the construction of new concrete buildings and cause sick house syndrome is detected, the indoor air contaminated is discharged to the outside and clean outdoor air is introduced into the room. Therefore, it is possible to create a pleasant indoor environment, and heat loss can be reduced by performing heat exchange between the indoor air discharged to the outside through the heat exchanger and the outdoor air introduced into the room in the process of ventilating the indoor and outdoor air.

In addition, when a concrete building is newly constructed and a certain period of time is no longer detected as a harmful component that causes sick house syndrome, ventilation is performed by circulating back to the room after purifying through the filter unit 80 without discharging the indoor air to the outside. It can prevent or minimize the heat loss problem that occurs during operation.

In particular, by introducing a portion of fresh outdoor air in the process of purifying and recycling indoor air, it is possible to create a more comfortable indoor environment. That is, since the concentration of carbon dioxide emitted by people increases indoors, the indoor air can be kept fresh by introducing outdoor air and lowering the concentration of carbon dioxide.

In addition, when the outdoor air fan is operated and the outdoor air or indoor air is introduced into the room, when the oxygen generator and the silver ion generator installed at the outlet side of the outdoor air passage are operated, oxygen and anions generated from the oxygen generator and the anion generator are generated. As it flows into the room, a more pleasant indoor environment can be created.
