Air cleaning circulation apparatus connected to air conditioner for removing ultrafine dust using a heat source of air conditioner

The present invention relates to an ultra-fine dust-removing type air cleaning circulation device using a heat source of an air conditioner to improve indoor air quality.

In general, even if the concentration of fine dust or ultrafine dust is high in the air, indoors are filled with dust and pollutants remain, and in a _{situation where the concentration of CO 2} is high, indoor polluted air is discharged to the outside and outdoor air is supplied to the room. Ventilation is essential.

To this end, in places used by many people, such as banks, restaurants, shopping malls, government offices, offices, etc., to improve indoor air quality, there is an air circulation device that discharges polluted indoor air to the outside and supplies fresh outdoor air to the interior. It is equipped.

This air circulation device has a simple structure in which air is circulated by circulating air by discharging the bet to the outside through one blowing fan and by discharging the bet to the outside through the other. Therefore, the temperature is relatively high due to heating in winter and summer. There is a problem in that cooling and heating efficiency is deteriorated as the inside air having a relatively low temperature is discharged to the outdoors as it is by cooling.

In order to solve this problem, an air clean circulation device was devised by the applicant, which is provided with an air supply module and an exhaust module, and the lower end of the air supply module and the upper end of the exhaust module communicate with each other by a return duct, and the interior of the air supply module. The air supply fan and the air supply damper are provided, the exhaust fan and the exhaust damper are provided inside the exhaust module, and the return damper is provided inside the return duct.

That is, the air is supplied to the room through the air supply module and the internal air is discharged to the outside through _{the exhaust module. However, depending on the indoor temperature and CO 2} concentration, the internal air discharged from the exhaust module is returned to the room through the air supply module. It is designed to keep the indoor air pleasant and clean at all times by controlling the return amount of the internal air and the amount of outside air supplied.

However, in the above-described air cleaning circulator, the amount of outside air supplied to the room through the air supply module is extremely limited, and smooth ventilation is not possible as the internal air returning from the exhaust module to the air supply module and the internal air are at the same temperature. Therefore, there is a limit to reducing the indoor CO _{2 concentration.}

Therefore, to ensure smooth ventilation and _{effectively reduce the indoor CO 2} concentration, an air clean circulator having a structure that can increase the amount of outside air supplied by supplying cold or warm air with a temperature relatively lower or higher than that of internal air to the air supply module. The development of is desperate.

It may be composed of a device 400 and a drain means 500, a temperature sensor 600, a CO ₂ sensor 700 and a controller 800.

First, the air supply module 100 may supply outside air existing outdoors to the inside, purify it, and then supply it indoors.

To this end, the air supply module 100 has a cylindrical shape in which the inflow passage 110 is formed through in the longitudinal direction from one end to the other end, and is installed so that one end is connected to the room and the other end is connected to the outdoors. An inlet 120 is installed, a pipe connector 130 is installed at one end of the other end, and an outside air supply port 140 through which outside air is supplied to the room may be installed at the other end.

In addition, an air supply fan 150 may be installed at the inside of the other end of the air supply module 100 to supply outside air to the room so that outside air is introduced through the outside air inlet 120 and supplied to the room through the outside air supply port 140.

In addition, in the middle of the air supply module 100, after flowing into the inside through the outside air inlet 120, a multi-stage purification process that filters out foreign substances, ultrafine dust and various bacteria contained in the outside air passing through the inflow channel 110. The filter member 160 may be installed.

Here, the multi-stage filter member 160 may include a pretreatment filter 161, an intermediate filter 162, and a HEPA filter 163 that are sequentially disposed from the rear end of the air supply module 100 along the front end direction.

However, the multi-stage filter member 160 includes a gap between the pre-processing filter 161 and the intermediate filter 162, the gap between the intermediate filter 162 and the HEPA filter 163, and the outer surface of the pre-processing filter 161 and the air supply module 100. The pretreatment filter 161 and the middle so that the gap between the inner surface of the, the gap between the outer surface of the intermediate filter 162 and the inner surface of the air supply module 100, and the gap between the outer surface of the HEPA filter 163 and the inner surface of the air supply module 100 do not occur. A pressure fixing means (not shown) for pressing and fixing the filter 162 and the HEPA filter 163 inside the air supply module 100 may be further included.

Meanwhile, an air supply damper 170 may be installed inside the outside air inlet 120 to adjust the supply amount of outdoor air introduced through the outside air inlet 120 and supplied to the room through the outside air supply port 140.

That is, the air supply damper 170 variably adjusts the internal space of the outdoor air inlet 120 according to the rotation angle, so that the supply amount of the outside air supplied to the room through the outdoor air supply port 140 can be adjusted.

Next, the exhaust module 200 _{may introduce the bet existing indoors into the interior so that the indoor CO 2} concentration can be appropriately adjusted, and then discharge it to the outdoors.

To this end, the exhaust module 200 has a cylindrical shape in which the discharge passage 210 is penetrated along the longitudinal direction from one end to the other end, and is installed so that one end is connected to the indoor and the other end is connected to the outdoors, and the bet is introduced into one end. 220 may be installed and a bet outlet 230 for discharging the bet to the outside may be installed at the other end.

In addition, an exhaust fan 240 may be installed inside the other end of the exhaust module 200 to supply the bet to the outside so that the bet is introduced through the bet inlet 220 and discharged to the outdoors through the bet outlet 230.

In addition, an exhaust damper 250 may be installed inside the bet inlet 220 to control the discharge amount of bet that is introduced through the bet inlet 220 and discharged to the outdoors through the bet outlet 230.

That is, the exhaust damper 250 variably adjusts the internal space of the bet inlet 220 according to the rotation angle, so that the supply amount of the bet discharged to the outside through the bet outlet 230 can be adjusted.

Next, the direct connection pipe 300 supplies cold air or warmth discharged from the supply duct S of the air conditioner (A) to the inside of one end of the air supply module 100 to maximize the supply amount of outside air while maintaining the temperature of the inside air. I can.

That is, the cold air or warmth directly discharged from the supply duct S of the air conditioner (A) has a temperature that is much lower or much higher than the internal air, so that the temperature difference with the outside air can be further increased.

Therefore, the direct piping 300 supplies cool air discharged from the supply duct S of the air conditioner A in the summer to the inside of one end of the air supply module 100, and discharges it from the supply duct S of the air conditioner A in winter. As the warmth is supplied to the inside of one end of the air supply module 100, the supply amount of the outside air supplied to the room through the air supply module 100 can be maximized due to a large temperature difference with the outside air.

To this end, the direct connection pipe 300 has one end connected to the pipe connector 130 of the air supply module 100 and the other end connected to the supply duct S of the air conditioner (A) installed indoors, and the cold or warm air discharged from the supply duct. It can be directly supplied to the inside of one end of the air supply module (100).

That is, as cold air or hot air having a relatively much lower or much higher temperature than the bet through the direct connection pipe 300 is supplied from the air conditioner (A) to the air supply module 100, the air supply module 100 enters the room. As the temperature difference with the supplied outdoor air becomes relatively larger, the supply amount of the outside air can be greatly increased while maintaining the temperature of the inside air stably.

Accordingly, the amount of outdoor air supplied to the room is increased, and the indoor CO ₂ concentration, which is bound to increase due to indoor life, can be quickly reduced, and thus indoor air quality can be greatly improved.

Here, inside the pipe connector 130 of the air supply module 100, the internal space of the pipe connector 130 according to the rotation angle so that the amount of cold air or hot air supplied to the air supply module 100 through the direct connection pipe 300 can be adjusted. An adjustment damper 180 for variable adjustment may be installed.

In addition, a thermal insulation material (not shown) may be installed on the outer surface of the direct connection pipe 300 so that the temperature of cold or warm air is maintained until supply to the air supply module 100 is completed.

At this time, the thermal insulation material may be wound on the outer surface of the direct connection pipe 300 in a roll form, and may be made of a material including foam resin and airgel for excellent insulation performance.

Meanwhile, the air conditioner (A) may be composed of a ceiling type air conditioner previously installed on the ceiling of the room. In addition, the supply duct may be composed of one sub-duct that is not used among the four supply ducts included in the ceiling type air conditioner.

In other words, as it is possible to use the previously installed ceiling air conditioner without additional installation of the air conditioner (A), it is possible to exclude restrictions according to the installation space and reduce cost, thereby exhibiting an economically efficient advantage.

Next, the heat exchange element 400 is installed inside one end of the air supply module 100 to supply cold or warm air to the air supply module 100 through a direct connection pipe 300 and the outside air inlet 120 of the air supply module 100. ), it is possible to induce efficient heat exchange between the outside air introduced through.

To this end, the heat exchange element 400 may be made of an aluminum material having excellent thermal conductivity, and a plurality of ventilation holes 411 and 421 may be formed of a primary heat exchange plate 410 and a secondary heat exchange plate 420 through each of which is formed before and after. .

At this time, the primary heat exchange plate 410 may have a convex shape in the center along the direction of the outside air supply port 140, and a mixing outlet hole 412 that is relatively larger than the ventilation holes 411 and 421 may be formed at the center.

And the secondary heat exchange plate 420 is arranged to be spaced apart from the rear of the primary heat exchange plate 410 and has a convex shape along the direction of the outside air inlet 120, and has a relatively larger enlargement than the ventilation holes 411 and 421 on both sides. Outflow hole 422 may be formed.

That is, the primary heat exchange plate 410 is a mixture of cold air or hot air supplied to the air supply module 100 through the direct connection pipe 300 and the external air introduced through the air inlet 120 of the air supply module 100 at the center. It can be guided to be uniformly mixed while passing naturally through the outlet hole 412.

In addition, the secondary heat exchange plate 420 may guide the mixed fluid that has passed through the mixing outlet hole 412 of the primary heat exchange plate 410 to naturally pass through the enlarged outlet hole 422 located on both sides and spread widely. .

Therefore, the heat exchange element 400 is provided through the cold air or warmth supplied through the direct connection pipe 300 by the primary heat exchange plate 410 and the secondary heat exchange plate 420, and the outside air inlet 120 of the air supply module 100. It is possible to assist in effective heat exchange between incoming external air.

Here, the first heat exchange plate 410 and the second heat exchange plate 420 may receive heat of cold air or warm air supplied through the direct connection pipe 300 and hold the heat for a predetermined time.

Therefore, even if the indoor temperature corresponds to the set temperature of the air conditioner (A) and the operation of the air conditioner (A) is temporarily stopped, the primary heat exchange plate 410 and the outside air introduced through the air inlet 120 of the air supply module 100 As the heat held by the secondary heat exchange plate 420 is transferred, outside air can be smoothly supplied to the room.

Next, the drain means 500 connects the cold air or warmth supplied to the air supply module 100 from the inside of one end of the air supply module 100 through a direct connection pipe 300 and the outside air inlet 120 of the air supply module 100. Moisture generated due to the temperature difference between the outside air introduced through can be discharged to the outside.

To this end, the drain means 500 is installed on the inner bottom surface of one end of the air supply module 100 to support and collect moisture, and one end is connected to one side of the water supply module 510 and the other end is connected to the air supply module 100. ) And exposed to the outside of the air supply module 100 may be configured as a drain pipe 520.

Accordingly, moisture generated inside one end of the air supply module 100 is collected on the drip plate 510, and the moisture collected on the drip plate 510 can be discharged to the outside through the drain pipe 520.

Here, the drain pipe 520 may be connected to a drain pipe (D) provided in the air conditioner (A). Then, since there is no need to separately install a pump for discharging moisture, the piping structure can be simplified and piping construction can be facilitated.

Next, the temperature sensor 600 and the CO ₂ sensor 700 are respectively installed indoors _{to measure the indoor temperature and the CO 2} concentration, respectively.

Finally, the air supply damper 170, the exhaust damper 250, and the control damper 180 according to the indoor temperature and CO ₂ concentration measured by the temperature sensor 600 and the CO _{2 sensor 700, respectively, by the controller 800.} Can be controlled.

That is, the controller 800 is based on the measured ambient temperature from the temperature sensor 600 as corresponding to a set temperature which is set in accordance with the input operation of the user the CO ₂ concentration measured at the CO ₂ sensor 700 is predetermined by the user, The rotation angle of the air supply damper 170, the exhaust damper 250, and the control damper 180 can be automatically adjusted to correspond to the CO _{2 concentration.}
