The present invention relates to a regenerative evaporative cooling ventilator and a method of operating the same, and more particularly, to construct a ventilator using a regenerative evaporative air conditioner and to operate it according to indoor and outdoor temperature conditions so as to achieve optimal ventilation performance. It relates to a regenerative evaporative cooling ventilator and a driving method thereof.

In relation to the existing air conditioning system, various problems such as excessive energy consumption due to increased demand for air conditioning and heating, ozone layer destruction by refrigerant, and global warming have been raised. Furthermore, the enactment of regulations on indoor temperature, humidity and cleanliness has led to the expansion of air-conditioning and heating systems. As the regulations on ventilation have been strengthened, the energy consumption by air-conditioning systems has greatly increased due to the increase of air / heating loads in summer / winter. It is expected to be.

In order to cope with these problems, an energy recovery ventilation system has been devised to reduce the ventilation load by transmitting sensible and latent heat between indoor exhaust and outdoor intake air.

However, the energy recovery rate of the energy recovery ventilator is usually about 60%, the ventilation load is reduced by the action of the ventilator, but the increase in the cooling / heating load due to the ventilation is a significant problem. In particular, the latent heat recovery rate of the conventional ventilation device is lower than the sensible heat recovery rate, so that the energy recovery rate is further reduced during the summer when the latent heat energy accounts for a large part of the ventilation energy, and the problem of failing to appropriately reduce the cooling load increase due to the ventilation is a problem. there was.

In view of the necessity as described above, the present invention can not only significantly reduce the summer ventilation load, but also can reduce the cooling load compared to the case without the ventilation, and furthermore, eco-friendly regenerative evaporative cooling ventilation apparatus and its It is an object to provide a driving method.

In order to achieve the above object, the regenerative evaporative cooling ventilator according to an aspect of the present invention is a regenerative evaporative cooler; An air distributor connected to the regenerative evaporative cooler so as to communicate with the regenerative evaporative cooler; A duct communicatively connected to the air distributor, the duct providing a flow passage of the inflow or outflow of air; And a bleeding damper mounted on the indoor side of the duct so as to be openable and openable, and bleeds a portion of the air flowing out of the regenerative evaporative cooler to the side of the regenerative evaporative cooler and exhausts it to the outside.

In addition, the operating method of the regenerative evaporative cooling ventilation apparatus according to another aspect of the present invention includes the steps of calculating a high temperature of the indoor and outdoor temperature; If the outdoor temperature is high, some of the air introduced through the dry channel of the regenerative evaporative cooler from the outside is added to the wet channel supplied with water to exhaust the outdoor air, and if the indoor temperature is high, the external air is discharged through the gun channel. At the same time as the indoor and the indoor air is exhausted through the wet channel is not supplied with water.

Furthermore, the operation method of the regenerative evaporative cooling ventilation apparatus according to another aspect of the present invention includes the steps of calculating a high temperature of the indoor and outdoor temperature; When the outdoor temperature is high and its dew point temperature is higher than the wet bulb temperature of the indoor air, introducing outdoor air through the dry channel of the regenerative evaporative cooler and simultaneously evacuating the indoor air through the wet channel to which water is supplied. .

Hereinafter, a regenerative evaporative cooling ventilator according to a preferred embodiment of the present invention and a driving method thereof will be described in detail with reference to the accompanying drawings.

1 is a perspective view of the regenerative evaporative cooling ventilator according to an embodiment of the present invention from an outdoor side, and FIG. 2 is a perspective view of the regenerative evaporative cooling ventilator according to an embodiment of the present invention from an indoor side.

As illustrated in the drawings, a regenerative evaporative cooling ventilator according to an exemplary embodiment of the present invention is a regenerative evaporative cooler 100, an air distributor 200, a duct 300, and a bleeding damper 400. ).

The regenerative evaporative cooler 100, as can be seen in Figure 3 showing its principle, a dry channel (110) that is not supplied with water and a wet channel (wet channel) can be supplied with water, 130). Accordingly, some of the air (outdoor intake) introduced into the room through the wall (W) through the dry channel 110 is additionally added to the wet channel 130, and this additional air is supplied with water from the wet channel 130. In case such water is cooled by evaporation. This cooled bleed air removes sensible heat from the relatively high temperature outdoor intake and lowers the temperature of the outdoor intake. Accordingly, the outdoor intake air having passed through the gun channel 110 and having a lower temperature is discharged to the room, and additional air that has undergone heat exchange with the gun channel 110 while passing through the wet channel 130 is discharged to the outside. At this time, the inside of the dry channel 110 and the wet channel 130 is provided with a dry channel pin 115 and a wet channel pin (135, see Figs. 4 and 5 above) to improve the heat transfer efficiency. In particular, the wet channel pin 135 is formed with a louver or a hole (not shown), it is configured to allow the water to be passed through. Here, the regenerative evaporative cooler 100 does not use any refrigerant other than water, and thus does not cause any problems such as ozone layer destruction and greenhouse effect by CFC (chlorofluorocarbon) based refrigerant. In addition, except for an electric input for supplying water to the wet channel 130, it requires little energy and thus is economical due to low energy consumption. Furthermore, the regenerative evaporative cooler 100 further includes a water supply device 150 for supplying water to the wet channel 130 as described above, which will be described in detail with reference to FIG. 6.

Referring again to FIGS. 1 and 2, the air distributor 200 is connected to communicate with the regenerative evaporative cooler 100 to allow the indoor or outdoor air to flow therein or to flow therefrom. The air distributor 200 includes an outdoor air distributor 210 connected to communicate with the outdoor side of the regenerative evaporative cooler 100 and an indoor air distributor 230 connected to communicate with the indoor side. The outdoor side air distributor 210 has a dry channel inlet air distributor 211 communicating with the gun channel 110 so that the outside air flows into the gun channel 110 again, and the air flowing out of the wet channel 130 flows outdoors. It is divided into a wet channel outflow air partial exhaust (213) to be discharged. In addition, the indoor air distributor 230 includes a dry channel outflow air distributor 231 for discharging the air flowing out of the dry channel 110 into the room, and a wet channel inlet air for introducing air into the wet channel 130 from the room. The divider 233 is divided.

The air distributor 200 will be described in more detail with reference to FIGS. 4 and 5.

4 is a perspective view illustrating the regenerative evaporative cooler and the outdoor air distributor viewed from the direction of FIG. 1, and FIG. 5 is a perspective view illustrating the regenerative evaporative cooler and the indoor air distributor viewed from the direction of FIG. 2.

Referring to FIG. 4, the outdoor air distributor 210 includes a dry channel inlet air distributor 211 connected to communicate with the dry channel 110, and a wet channel outflow air distributor connected to communicate with the wet channel 130. 213). Here, the dry channel inlet air distributor 211 and the wet channel outlet air distributor 213 are hollow bodies each having a triangular cross section.

The first side 211a of the triangular cross section of the gun channel inlet air distributor 211 is connected to communicate with the gun channel 110 to be a passage through which outdoor air flows into the gun channel 110, and the second side 211b. Is opened to allow outdoor air to flow into the dry channel inlet air distributor 211. At this time, the third side 211c is in a blocked state.

The first side 213a of the triangular cross section of the wet channel outflow air distributor 213 is formed to communicate with the wet channel 130 to be a passage through which the air passing through the wet channel 130 is discharged to the outside. Furthermore, the second side 213b is opened so that air flowing out of the wet channel 130 through the first side 213a is finally discharged to the outside. At this time, the third side 213c is in a blocked state.

Here, the second side 211b of the dry channel inlet air distributor 211 is adjacent to the third side 213c of the wet channel inlet air distributor 213 and the third side of the dry channel inlet air distributor 211. 211c are alternately arranged adjacent to the second side 213b of the wet channel outflow air distributor 213. Accordingly, the outdoor air introduced through the dry channel inlet air distributor 211 and the air discharged to the outside through the wet channel outlet air distributor 213 are separated from each other and are not mixed with each other. As a result, the cooling efficiency due to the ventilation action by the regenerative evaporative cooling ventilator according to the present invention is not lowered by the mixing of the inflow and outflow air.

Referring to FIG. 5, the indoor air distributor 230 communicates with the gun channel 110 and flows through the gun channel outlet air distributor 231 for discharging the outdoor air passed therethrough to the room, and the gun channel 110. And a wet channel inlet air distributor 233 in communication with the wet channel 130 for discharging the additionally bleed air or indoor air which has been extracted to some of the air.

Here, the dry channel outflow air distributor 231 and the wet channel inlet air distributor 233 are also hollow bodies having a triangular cross section, and the first sides 231a and 233a of these 231 and 233 are the dry channel 110, respectively. ) And the wet channel 130. The second sides 231b and 233b of these 231 and 233 are opened so as to communicate with the room, respectively, to discharge the outdoor intake air passing through the gun channel 110 to the room, or to extract bleed air or indoor air into the wet channel inlet air distributor. Inflow to (233). At this time, the third sides 231c and 233c of these 231 and 233 are configured to be blocked.

Here, the second side 231b of the dry channel inlet air distributor 231 and the third side 233c of the wet channel inlet air distributor 233 are disposed adjacent to each other. In addition, the third side 231c of the former 231 and the second side 233b of the latter 233 are also adjacent to each other. Accordingly, the discharge direction of the air discharged into the room through the former 231 and the inflow direction of the air introduced into the wet channel 130 through the latter 233 are separated from each other so that there is no fear of mixing them. This has the advantage of preventing the deterioration of the efficiency of ventilation and cooling as they are mixed.

Referring back to FIGS. 1 and 2, the duct 300 is connected to communicate with the outdoor air distributor 210 and is connected to communicate with the outdoor air duct 310 extending to the outdoor side and the indoor air distributor 230. And an indoor side duct 330 extending to the indoor side.

The outdoor side duct 310 may be divided into an outdoor intake duct 311 communicating with the dry channel inlet air distributor 211 and an outdoor exhaust duct 313 in communication with the wet channel outlet air distributor 213. In addition, the indoor side duct 330 is divided into an indoor air supply duct 331 in communication with the dry channel outflow air distributor 231, and an indoor exhaust duct 333 in communication with the wet channel inlet air distributor 233.

The bleeding damper 400 can open and close the bleeding channel 410 opened therein so as to communicate the indoor air supply duct 331 of the indoor side duct 330 and the indoor exhaust duct 333. Is fitted. The additional damper driver 751 (see FIG. 10) for driving the additional damper 400 to implement the opening and closing operation may be, for example, a motor that rotates an axis (not shown) of the additional damper 400 to control its opening and closing. (Not shown) can be used.

Regenerative evaporative cooling ventilation apparatus according to an embodiment of the present invention may further include an exhaust damper 500 and the bypass duct (600).

The exhaust damper 500 is mounted to open and close the exhaust channel 510 formed at an interior end of the indoor exhaust duct 333. By adjusting the opening and closing degree of the exhaust damper 500, it is possible to adjust the amount of indoor air introduced into the wet channel 130 through the indoor exhaust duct 333.

Bypass duct 600 is able to independently discharge the indoor air to the outside without communicating with the regenerative evaporative cooler (100). Accordingly, the bypass duct 600 is in direct communication with the outdoor exhaust duct 313 of the outdoor side duct 310. The bypass channel 630 is formed at the indoor end of the bypass duct 600, and a bypass damper 610 is mounted to open and close the channel 630.

Each of the above-described exhaust damper 500 and the bypass damper 610 is equipped with an exhaust damper driver 753 and a bypass damper driver 755 (see FIG. 10 above), and they are the same as the above-described additional damper driver 751. Can be configured.

In order to clarify the connection between the components described above will be described with reference to FIG.

6 is a cross-sectional conceptual view for comprehensively explaining the internal structure of the regenerative evaporative cooling ventilator of FIG. 1.

As illustrated in the drawings (and FIGS. 1 and 2), the outdoor air sucked from the outdoor intake duct 311 passes through the outdoor side air distributor 210 (specifically, the dry channel inlet air distributor 211). The regenerative evaporative cooler 100 (specifically, the dry channel 110) passes through. The air passing through the dry channel 110 is distributed to the indoor air supply duct 331 through the indoor air distributor 230 (specifically, the dry channel discharge air distributor 231) and finally discharged to the room (F1). ).

Some of these flows F1 are additionally added as the additional damper 400 for opening and closing the additional channel 410 formed in communication between the indoor air supply duct 331 and the indoor exhaust duct 333 is opened (F2a). The air supply duct 331 forms a flow F2 flowing back into the regenerative evaporative cooler 100 (more specifically, the wet channel 130) through the indoor exhaust duct 333. Further, when the exhaust damper 500 is opened, the flow F2b of the indoor air through the indoor exhaust duct 333 also passes through the wet channel 130 to discharge the exhaust flow F2 discharged to the outdoor exhaust duct 313. Can be formed.

At this time, the water supply device 150 injects water into the flow (F2a) of the bleed air passing through the wet channel 130, the bleed air is deprived of heat in accordance with the evaporation of the water again suction of the dry channel 110 Heat exchange with outside air. Here, the water supply device 150 includes a water supply and spray device 151 for spraying water to the additional air, and a storage and drainage device 153 for storing and draining the injected water. The water supply device 150 also includes a circulation pump 155 for circulating the stored water and a circulation pipe 157 for providing a path for circulation of the water.

In order to smooth the flow (F1) for the inflow of air into the interior and the flow (F2) for the exhaust to the outside in the outdoor intake duct 311 and the outdoor exhaust duct 313, respectively, the intake blower 350 And an exhaust blower 370 is installed.

 Next, a method of operating the regenerative evaporative cooling ventilator according to an embodiment of the present invention will be described with reference to FIGS. 7 to 10.

7 is a schematic view for explaining a summer operation method of the regenerative evaporative cooling ventilation apparatus according to an embodiment of the present invention.

As illustrated in the figure, in the summer, the outdoor temperature is higher than the room temperature, it is necessary to cool the air flowing into the room from the outdoor. Accordingly, a flow F1 in which outdoor air flows into the gun channel 110 of the regenerative evaporative cooler 100 is formed by the operation of the intake blower 350. This flow (F1) is discharged into the room through the indoor air supply duct 331, a part of which forms a flow (F2a) to be added to the indoor exhaust duct 333 by the opening of the bleed damper (400). At this time, the exhaust damper 500 that opens and closes the indoor exhaust duct 333 is in the closed state, and only the flow F2a of the bleed air is through the wet channel 130 of the regenerative evaporative cooler 100. 313 to form a flow (F2) outflow. At this time, the exhaust blower 370 may be operated in order to facilitate the flow (F2).

Furthermore, when the flow F2a of the bleed air passes through the wet channel 130, water is injected by the water supply device 150. This water is evaporated while the heat is removed from the flow of additional air (F2a) by the evaporative cooling effect, and thus the cooled air again exchanges heat with the flow of outdoor air (F1) flowing through the dry channel 110. . As a result, the flow F1 of external air introduced into the room through the gun channel 110 is discharged to the room while being cooled to a predetermined level. In this case, only the water supply device 150, and further, the electric blower 350 and 370 may require electrical input for ventilation, thereby greatly reducing the ventilation load. In addition, since the cooling of the air flow (F1) introduced into the room by the ventilation is accompanied, an additional advantage is provided that the cooling load for cooling the room is rather reduced.

If the room is completely enclosed during this ventilation operation, the amount of air as much as the amount of indoor air supply should be exhausted to the outside in order to prevent the increase of the indoor static pressure caused by the indoor air supply. To this end, the bypass damper 610 may be opened so that some of the indoor air may be exhausted to the outside through the outdoor exhaust duct 313 without passing through the regenerative evaporative cooler 100 through the bypass duct 600. .

8 is a schematic view for explaining a method of operating when the outdoor humidity is high in the summer operation method of the regenerative evaporative cooling ventilation apparatus according to an embodiment of the present invention.

As illustrated in the figure, when the outdoor humidity is very high and the dew point temperature of the outdoor air is higher than the wet bulb temperature of the indoor air, the indoor air is cooled rather than the regenerative evaporative cooling that cools and extracts the bleed air of the outdoor intake air as described above. Cooling the outdoor intake air by indirect evaporative cooling according to the exhaust box is more effective.

To this end, the bleed damper 400 is closed so that the flow F1 of the outdoor intake air is not bleeded, and the exhaust damper 500 is opened to allow the indoor air to pass through the indoor exhaust duct 333. It forms a flow (F2b) flowing into the wet channel (130). This flow F2b is supplied with water while passing through the wet channel 130. Accordingly, the flow is taken out by the evaporative cooling effect and cooled to cool the flow F1 of the outdoor suction air introduced through the dry channel 110, and then flow out to the outside through the outdoor exhaust duct 313. F2) is formed. Accordingly, the flow F1 of the outdoor suction air supplied to the room discharges the cooled air to the room rather than the outdoor air. In this case, the amount of indoor air introduced into the wet channel 130 may be adjusted by adjusting the opening degree of the bypass damper 610.

9 is a schematic view for explaining a winter operation method of the regenerative evaporative cooling ventilation apparatus according to an embodiment of the present invention.

As illustrated in the figure, in the winter season when the outdoor temperature is lower than the room temperature, the flow F1 of the outdoor suction air sucked into the room is not extracted but is discharged to the room through the indoor air supply duct 331. To this end, the additional damper 400 maintains a closed state. In addition, the exhaust damper 500 is opened, so that the indoor air forms a flow F2b flowing into the wet channel 130 through the indoor exhaust duct 333.

Here, the flow (F2b) of the indoor air flowing into the wet channel 130 is not supplied to the water unlike in the previous summer operating method. In other words, the water supply device 150 does not operate during winter operation. Accordingly, the flow F2b of the indoor air forms the flow F2 discharged to the outside through the outdoor exhaust duct 313 without being evaporated and cooled in the wet channel 130.

However, the flow F1 of outdoor air passing through the dry channel 110 into the room receives sensible heat by the temperature difference from the flow F2b of the indoor air discharged through the wet channel 130 to the outside. The temperature rises. As a result, the energy of the flow F2b of the indoor air exhausted to the outside is recovered again and supplied to the room. Accordingly, not only is the indoor ventilation smooth in winter, but also the heating load on the indoor air is reduced because the air discharged into the room absorbs the energy of the exhausted air.

10 is a schematic view for explaining a control method of the operation of the regenerative evaporative cooling ventilation apparatus according to an embodiment of the present invention.

In order to automatically control the regenerative evaporative cooling ventilation apparatus according to an embodiment of the present invention, the regenerative evaporative cooling ventilation apparatus according to an embodiment of the present invention includes a control unit 710, an indoor temperature sensor 721, and an outdoor unit. The apparatus may further include a temperature sensor 723, a temperature input unit 731, and a humidity input unit 733.

The indoor temperature sensor 721 is disposed at the indoor side to measure the indoor temperature, and the outdoor temperature sensor 723 is disposed at the outdoor side to measure the outdoor temperature. The temperature measured at these is input to the control unit 710. Based on this input, the control unit 710 calculates a higher temperature among indoor and outdoor temperatures to determine whether to operate the regenerative evaporative cooling ventilator in the summer operation method or the regenerative evaporative cooling ventilator in the winter operation method. do.

Based on the above determination, the control unit 710 controls the bleeding damper driver 751, the bleeding damper driver 750 and the bypass damper drift 755, respectively, and corresponds to the squeezed damper 400 and exhaust. By regulating the opening and closing of the damper 500 and the bypass damper 610, the regenerative evaporative cooling ventilation apparatus is operated according to the determined operation mode. In addition, by operating the intake blower 350 and the exhaust blower 370 as necessary to facilitate the intake flow (F1) and exhaust flow (F2).

In addition, since the temperature input unit 731 is provided, the user may directly set the outdoor and indoor temperatures without input by the temperature sensors 721 and 723. Furthermore, having a mode selector (not shown) for selecting a summer and winter mode does not even require a temperature input, thereby making it easier to determine a method of operating a regenerative evaporative cooling ventilator.

In addition, a humidity input unit 733 may be provided to select an operation method (operation method illustrated in FIG. 8) according to the case where the outdoor humidity is high during the summer season. Furthermore, it may also be simple to make such a driving scheme selectable through a separate mode selector.

In the above description, the regenerative evaporative cooling ventilation apparatus and its operation method according to an embodiment of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the embodiments and drawings disclosed herein, Various modifications can be made by those skilled in the art within the scope of the technical idea of the invention.

As described above, the regenerative evaporative cooling ventilator according to the present invention can greatly reduce the ventilation load since only the electricity supply to the water supply apparatus and the blower is provided for ventilation of the indoor air.

Furthermore, cooling or heating loads in the summer or winter can be greatly reduced because cooling or heating of the air flowing into the room is accompanied by ventilation.

In addition, the operating method of the regenerative evaporative cooling ventilation apparatus according to the present invention can vary the operation method according to the temperature and humidity conditions of the indoor and outdoor, so that the effect of optimal ventilation and heating and heating in each condition is generated.
