Description

Cooling system for indoor spaces using outside air

[0001] The present invention relates to a cooling system for an indoor space using outside air, and more particularly, to a cooling system installed in an indoor space with a lot of heat emission such as a base station, a server data room, or a data storage room, and thereby reduces power consumption by bringing in outside air into the room and using it to lower the indoor temperature, while removing foreign substances including dust contained in the outside air and then bringing in clean outside air into the room, thereby providing a technology for implementing a cooling system that is economical and maximizes maintenance efficiency.

[0002] With the rapid development of the wireless communications industry, base stations are being installed and operated to build broadband, high-capacity wireless networks. Base stations house numerous communication devices, enabling them to connect remote communication lines, thereby establishing wireless networks. However, the operation of these communication devices within these base stations, i.e., indoor spaces, generates significant heat.

[0003] Meanwhile, if the heat generated from an unmanned base station is not cooled down in a timely manner, it can interfere with the normal operation of communication equipment, affect the communication network, or even cause a fire. Therefore, it is very important to maintain the internal temperature of an unmanned base station at an appropriate temperature. To this end, in the past, a dedicated cooling facility, as in Korean Patent Publication No. 10-2006-0069702, was used to forcibly lower the temperature to maintain the indoor temperature at an appropriate temperature.

[0004] However, in this case, the indoor temperature is forcibly lowered by relying on air conditioning equipment, which not only results in low cooling efficiency, but also causes the continuous operation of the air conditioning equipment, resulting in very high power consumption and increased cooling costs, and other problems are occurring.

[0005] Accordingly, Korean Patent Publication No. 10-2014-0121632 discloses an air conditioning technology that utilizes outside air for cooling an indoor space, but uses a HEPA filter to remove a large number of foreign substances contained in the outside air. Although the HEPA filter has the advantage of removing foreign substances contained in the outside air, only a very small increase in cooling efficiency is expected due to the problem that the outside air pressure is not properly discharged by the HEPA filter. Therefore, there is a growing need for research and development of air conditioning technology that can solve the problem of using outside air but not properly discharging the outside air pressure, and maximize cooling efficiency.

[0006] Accordingly, the present invention is a cooling system installed in an indoor space with a lot of heat emission, such as a base station, a server data room, or a data storage room, and the first purpose of the present invention is to induce power consumption reduction by lowering the indoor temperature by bringing in outside air into the room.

[0007] In addition, the present invention has a second purpose of providing a technology for implementing a cooling system that is economical and maximizes maintenance efficiency by removing foreign substances, including dust, contained in the outdoor air using a dust collection facility when introducing outdoor air into a room before introducing the air into the room.

[0008] In order to achieve the above-described object, a system for cooling an indoor space using outside air, which is implemented as a computing device including one or more processors and one or more memories for storing commands executable by the processors, is characterized by including: an outside air supply unit having a supply fan that functions to introduce outside air into an indoor space to be conditioned, and transporting the introduced outside air through a first duct as the supply fan operates; a dust collection unit connected to an outside air outlet of the first duct, collecting foreign substances contained in the outside air using a dust collection facility, and providing the dust-collected outside air to the indoor space through a second duct; and an exhaust unit having an exhaust hood that draws in inside air, the temperature of which has increased due to heat generated in the indoor space, a third duct connected to the exhaust hood, and an exhaust fan connected to the third duct, and exhausting the inside air to the outside.

[0009] At this time, the above-described dust collection facility comprises: a case having a structure in which both sides are open, one side of the both sides being interconnected with an outside air outlet of a first duct to allow outside air to be introduced and the other side to allow outside air that has been dust-collected to be discharged; a dust collection module having a plurality of dust collection electrodes and a plurality of discharge electrodes installed adjacent to the dust collection electrodes, in which a flow path is formed along a transport path of the outside air inside the case; a cleaning module having a cleaning solution supply module, a fluid line for receiving cleaning solution from the cleaning solution supply module, and a cleaning nozzle installed to receive the cleaning solution from the fluid line and spray it toward the inside of the case; wherein the dust collection facility is preferably provided in a type including at least one of a vertical type in which the dust collection electrodes are installed vertically with respect to the installation surface, and a horizontal type in which the dust collection electrodes are installed horizontally with respect to the installation surface.

[0010] In addition, it is preferable that the above-described dust collection unit, when power is supplied to the dust collection module, apply a micro pulse voltage to the discharge electrode by the MPS (Micro Pulse System) to generate a corona discharge through the discharge electrode, thereby performing dust collection processing.

[0011] In addition, it is preferable that the above-described cleaning module further include a first driving means for providing a driving force to cause a cleaning nozzle extending from a fluid line to enter the interior of a dust collecting electrode and perform a reciprocating motion in the longitudinal direction of the dust collecting electrode; and a second driving means for providing a spray angle of a cleaning liquid ejected from the cleaning nozzle and a driving force for rotating the cleaning nozzle in at least one direction.

[0012] In addition, the above-described dust collection equipment preferably includes a first support means for supporting the dust collection electrode, and a second support means for supporting the discharge electrode, wherein the first support means further includes a vibration-type dust removal module including a vibration generator for providing vertical vibration or horizontal vibration corresponding to the longitudinal direction of the dust collection electrode, so that when vibration is applied to the dust collection electrode and the first support means by the vibration generator, contaminants adsorbed on the inner surface of the dust collection electrode lose their adsorption force due to the applied vibration and are removed.

[0013] In addition, it is preferable to further include an air injection type dedusting module including a compressed air tank that generates the compressed air described above, a supply line that supplies compressed air from the compressed air tank, and an air injection nozzle that injects the compressed air supplied through the supply line, and by the air injection type dedusting module, compressed air is injected into the inside of the dust collecting electrode, so that contaminants adsorbed on the inner surface of the dust collecting electrode lose their adsorption force by the compressed air and are removed.

[0014] In addition, it is preferable that an ozone removal filter made of a material including at least one of zeolite and activated carbon be installed in at least one area of ​​the second duct described above to prevent ozone generated during dust collection from entering the room.

[0015] In addition, it is preferable that the above-described exhaust hood be provided in multiple units in each area where a hot isle is formed in the indoor space.

[0016] In addition, it is preferable that a damper be installed in at least one of the first duct and the second duct described above, so that the amount of outside air supplied to the indoor space is controlled by the damper.

[0017] In addition, it is preferable to further include a main power supply unit that supplies power for driving a configuration including the above-described external air supply unit, dust collection unit, and exhaust unit; and, in preparation for a power outage of the main power supply unit, an emergency power supply unit based on an UPS (Uninterrupted Power Supply) that converts DC power stored in a storage battery into AC power in an emergency to supply emergency power to the configuration including the external air supply unit, dust collection unit, and exhaust unit.

[0018] In addition, in the case where the cooling system for an indoor space using the above-described outside air has multiple indoor spaces to be air-conditioned and the multiple indoor spaces exist on different floors in a building, it is preferable that the outside air supply unit, the dust collection unit, and the exhaust unit be installed in the indoor space or the outdoor space, and that the second duct be extended to have a branched line to supply dust-treated outside air to the indoor space of each floor, and that the third duct be provided with a line to collect the inside air taken in from the indoor space of each floor and exhaust it to the outdoor exhaust unit.

[0019] In addition, it is preferable that the computing device described above collects information on the area of ​​each indoor space and information on the indoor temperature detected by a temperature sensor installed in each indoor space, and that the amount of outdoor air supplied to each indoor space is controlled based on the area of ​​each indoor space and the indoor temperature information detected in each indoor space.

[0020] According to one embodiment of the present invention, in providing a cooling system installed in an indoor space with a lot of heat emission, such as a base station, a server data room, or a data storage room, the present invention can reduce power consumption by lowering the indoor temperature by introducing outside air into the room, thereby expecting a reduction in cooling costs.

[0021] In addition, according to one embodiment of the present invention, when outside air is simply introduced into a room, foreign substances such as dust contained in the outside air may have a negative effect on equipment within the base station and cause indoor space to be polluted. Therefore, by introducing outside air that has been dust-collected into the room so that clean outside air can be supplied to the indoor space, the above problem can be solved and the cooling efficiency of the indoor space can be maximized.

[0022] In addition, according to one embodiment of the present invention, by performing electrostatic precipitation by applying a micro pulse voltage to a discharge electrode by MPS, there is an effect that the amount of ozone generated during the dust collection process can be significantly reduced.

[0036] The present invention relates to a cooling system (10) for an indoor space using outside air, and more specifically, to a technology for reducing power consumption by using outside air to lower the temperature of the indoor space by introducing outside air into the indoor space when providing a cooling system (10) installed in an indoor space with a lot of heat emission such as a base station, a server data room, a data storage room, etc., and to solve the problem that when outside air is simply introduced into the indoor space, foreign substances including dust contained in the outside air are introduced into the indoor space, a second object is to implement a cooling system (10) that is economical and maximizes the efficiency of maintenance by introducing outside air that has been dust-collected using a dust collection facility into the indoor space, thereby allowing clean outside air to be introduced into the indoor space.

[0037] Hereinafter, the present invention will be described with reference to the attached drawings, and multiple drawings may be simultaneously referenced to explain one technical feature and components constituting the invention, and in the following description, some components are omitted or excessively enlarged or reduced in order to explain the functions of each component of the present invention, but it should be understood that the depicted details do not limit the technical features and scope of rights of the present invention.

[0038] First, the present invention will be described with reference to Fig. 1, which illustrates a configuration diagram of an indoor space cooling system (10) using outdoor air according to the present invention.

[0039] As shown in Fig. 1, the system (10) of the present invention includes, as a main component, an air supply fan that functions to introduce outside air into an indoor space to be air-conditioned, and an outside air supply unit (11) that transports the outside air introduced as the above-described air supply fan is driven through a first duct (D1).

[0040] The indoor space mentioned above can be understood as an indoor space that requires cooling due to high heat emission, and examples thereof include communication base stations, server rooms, and data centers.

[0041] The first duct (D1) described above may be understood as a concept of a conduit or passage used to transmit outside air, and this first duct (D1) is connected to a supply fan on one side to receive outside air drawn in from the supply fan, or is provided with an inside supply fan on one side to receive outside air drawn in, thereby performing the function of a passage through which outside air is drawn in.

[0042] In addition, the present invention includes a dust collection unit (12) that is connected to an outside air exhaust port provided on the other side of the first duct (D1) described above and collects and processes foreign substances contained in the outside air using a dust collection facility.

[0043] At this time, the dust collection facility described above can be provided in a form that largely includes a case (120), a dust collection module, and a cleaning module.

[0044] As an example, referring to FIG. 2, the above-described dust collection facility comprises a case (120) having a structure in which both sides are open, one side of the both sides being interconnected with an outside air outlet of a first duct (D1) to allow outside air to be introduced and the other side to allow outside air that has been dust-collected to be discharged, a dust collection module including a plurality of dust collecting electrodes (121) and a plurality of discharge electrodes (122) installed adjacent to the dust collecting electrodes (121), a cleaning module having a cleaning solution supply module, a fluid line for receiving cleaning solution from the cleaning solution supply module, and a cleaning nozzle installed to receive cleaning solution from the fluid line and spray it toward the inside of the case (120).

[0045] The case (120) described above may be provided in a form having a cavity so that an electrode plate can be installed inside, as shown in FIG. 2, and may have an open form on both sides corresponding to the direction in which outside air flows in order to function as a dust collection facility.

[0046] In addition, the dust collecting electrode (121) of the above-described dust collecting module can be installed in multiple numbers in a plate shape inside the case (120), and it is preferable that the installation form be formed long along the direction in which the outside air is introduced.

[0047] Referring to FIG. 8 as an example, various implementation examples of the dust collecting electrode (121) provided in a plate shape as mentioned in the present invention are illustrated in FIG. 8.

[0048] First, as schematically illustrated in FIG. 8, in the present invention, the dust collecting electrode (121) can be implemented in a wrinkled plate shape (i.e., a sine wave shape) with repeated valleys and peaks, as illustrated in (a) of FIG. 8. In addition, in the present invention, the dust collecting electrode (121) can be implemented in a shape with multiple folds, such as a square wave shape, as illustrated in (b) of FIG. 8, or in a zigzag shape or a triangular wave shape, as illustrated in (c) of FIG. In addition, in another embodiment of the present invention, the dust collecting electrode (121) can be provided in a cylindrical shape instead of a plate shape, and a discharge electrode (122) can be arranged in the center of the inside to have a cross-sectional shape as illustrated in (d) of FIG.

[0049] That is, it can be understood that the embodiments of (a) to (d) of FIG. 8 are embodiments for increasing the efficiency of dust collection with the discharge electrode (122) by providing a number of bends in the plate-shaped dust collection electrode (121) to maximize the amount of contact with the outside air, and various embodiments other than the embodiment illustrated in FIG. 8 may exist.

[0050] Meanwhile, the discharge electrode (122) will be understood as a wire or rod-shaped electrode installed adjacent to the dust collecting electrode (121), and is installed so that foreign substances contained in the outside air can be ionized while contaminants can be collected by the dust collecting electrode (121).

[0051] Referring to Fig. 11, the shape of the discharge electrode (122) and an exemplary installation example of the discharge electrode (122) in the dust collection facility can be examined. Specifically, the discharge electrode is provided as a wire or rod-shaped electrode as described above, and it is preferable that elastic parts (123) are provided at both ends to facilitate installation on a second support means for supporting the discharge electrode while providing a strong fastening force after installation, and a ring part (124) is provided at both ends extending from the elastic part (123), so that the end of the ring part (124) is hooked and coupled to a fastening area (1221) provided on the second support means, thereby having a fastening structure.

[0052] At this time, it is preferable that the fastening area (1221) provided in the second support means be provided in a position area that allows the discharge electrode (122) to be positioned at the inner center of the dust collecting electrode (121).

[0053] In addition, in FIG. 11, the description is limited to one installation example among various installation examples of the discharge electrode, but the discharge electrode of the present invention may have an elastic part (123) provided at least at one end and a configuration having a shape corresponding to a ring part (124) at the end of the elastic part (123), so as to be fastened to a second support means, and the present invention is not limited thereto.

[0054] Meanwhile, in the present invention, when the dust collecting electrode (121) is provided in a simple plate shape, the discharge electrode (122) is installed so as to be fixedly positioned between a plurality of current collecting electrodes as schematically illustrated in FIG. 2, and can be separated when necessary.

[0055] In addition, as another embodiment, when the dust collecting electrode (121) is provided in the shape of a wrinkled plate with a shape of repeating grooves and peaks as in the example described above, the discharge electrode (122) may be fixedly installed in a form such that it is accommodated in the grooved portion of the dust collecting electrode (121) to increase the ionization efficiency of pollutants by maximizing interaction with the dust collecting electrode (121).

[0056] In addition, the above-described dust collecting electrode (121) and discharge electrode (122) may be installed to be fixed by the first support means (1210) for supporting the dust collecting electrode (121) and the second support means (1220) for supporting the discharge electrode (122), in order to provide convenience in the case where they are separated for the purpose of cleaning or maintenance.

[0057] As an example, the first support means (1210) on which the dust collecting electrode (121) is supported may have a structure in which a groove corresponding to the single-sided shape of the dust collecting electrode (121) is provided, and the dust collecting electrode (121) is fitted into the groove and integrally connected, or is separated from each other.

[0058] In addition, as an embodiment, the second support means (1220) on which the discharge electrode (122) is supported may have a groove corresponding to the single-sided shape of the discharge electrode (122) similar to the first support means (1210) since the discharge electrode (122) is provided in the form of a wire or a rod, and the discharge electrode (122) may be fitted into the groove to be integrally coupled, or may have a structure in which they are separated from each other.

[0059] At this time, as another embodiment for the second support means (1220), in the present invention, a coupling plate is formed on both ends of the discharge electrode (122), and a coupling hole (1221) is provided in the second support means (1220) through which the coupling plate can pass in one direction, so that the coupling plate passing through the coupling hole (1221) in one direction is rotated in the axial direction (for example, rotated 90 degrees to 270 degrees) so that the coupling plate and the coupling hole (1221) have a twisted structure with respect to each other, thereby preventing the coupling plate from passing out of the coupling hole (1221), thereby fixing the discharge electrode (122) and, if necessary, the coupling plate may be rotated in the opposite direction of the coupling hole (1221) so as to be separated, but the present invention is not limited thereto.

[0060] Meanwhile, in the present invention, a sub-case (1201) may be included on the outside of the case (120) described above, which is installed to be blocked from the case (120), and an insulator may be included inside the sub-case (1201) to insulate the dust collecting electrode (121) and the discharge electrode (122) described above from each other. The insulator described above may be understood as a member referred to as an insulator, and may be understood as a concept including all components arranged and connected between the dust collecting electrode (121) and the discharge electrode to insulate them. In particular, in the present invention, since the insulator is installed in the sub-case (1201) separated from the case (120), even when collecting and processing outside air containing humidity and moisture, moisture does not come into contact with the insulator, and dust itself does not come into contact with the insulator, so that elements of insulation destruction can be prevented, and at the same time, damage to the insulator due to dust can be prevented, so that high dust collection efficiency can be maintained, and thus the effect of increasing the convenience of maintenance can be achieved.

[0061] On the other hand, the dust collection equipment of the present invention can be implemented as a vertical type in which the dust collection electrode (121) is installed vertically with respect to the installation surface, and a horizontal type in which the dust collection electrode (121) is installed horizontally with respect to the installation surface.

[0062] At this time, the vertical type dust collection facility described above may have an open area on the upper and lower sides of the case (120), and may have a path in which the lower side is connected to the outside air supply unit (11) so that outside air is introduced through the lower side, and the outside air that has been dust-collected is discharged through the upper side.

[0063] Meanwhile, since the dust collecting electrode (121) of the case (120) of the horizontal type dust collecting equipment described above is installed horizontally with respect to the installation surface, both sides of the longitudinal case (120) where the dust collecting electrode (121) is installed horizontally may have an open area, and one side of the two sides may be connected to the outside air supply unit (11) to receive outside air, and the other side may have a path for discharging the outside air that has been dust-treated.

[0064] However, in the case of a horizontal type dust collection facility, in preparation for the possibility that the cleaning solution may not be discharged smoothly when cleaning is performed by the cleaning module described later, the cleaning nozzle of the cleaning module is positioned on one side, and the side where the cleaning nozzle is positioned is implemented in a form inclined at a predetermined slope so that it is relatively higher from the installation surface than the other side, and a waste cleaning solution storage box for collecting the cleaning solution used for cleaning is positioned on one side of the other side so that the cleaning solution can be discharged.

[0065] Meanwhile, in the present invention, when power is supplied to the dust collection module, it is preferable to apply a micro pulse voltage to the discharge electrode (122) by the MPS (Micro Pulse System) to generate corona discharge through the discharge electrode (122) so that dust collection is performed. As an example, an MPS inverter power pack having specifications of an operating current of 0 to 60 mA, an output voltage of 8 to 20 KV, and a power consumption of 450 W may be used.

[0066] By performing the function of the aforementioned dust collector (12), the dust-treated outside air is supplied to the indoor space through the second duct (D2) and used for cooling the indoor space where the temperature has increased.

[0067] That is, in the present invention, when supplying outside air having a temperature lower than that of the indoor space to the indoor space, purified outside air is supplied to the indoor space, thereby inducing a cooling effect and ventilation effect using fresh air in the indoor space, and in particular, since the present invention does not require a separate cooling facility, the effect of reducing power consumption can be maximized compared to the conventional method of attempting to cool the indoor space using a cooling facility.

[0068] Meanwhile, the second duct (D2) described above can be understood as a concept of a conduit or passage used to transfer outside air, similar to the first duct (D1), and has a function of transferring purified air to an indoor space by forming a connection structure with the dust collector (12).

[0069] At this time, an ozone removal filter made of a material including at least one of zeolite and activated carbon may be installed in at least one area of ​​the second duct (D2) described above. This may be understood as a configuration for preventing residual ozone that has not been removed during the dust collection process of the aforementioned dust collection unit (12) from entering the room.

[0070] The cleaning module of the present invention includes a cleaning solution supply module (150), a fluid line, and a cleaning nozzle (151) as described above. Specifically, the cleaning nozzle (151) may have a form that extends from the fluid line (152) and enters the inside of the case (120). This can be understood as a configuration in which one end thereof faces the inside of the case (120), specifically, the inside of the dust collecting electrode (121).

[0071] More specifically, the cleaning module (15) of the present invention is a structure in which the cleaning liquid sprayed from the cleaning nozzle (151) extending from the fluid line (152) is sprayed into the interior of the dust collecting electrode (121), and further includes a first driving means for providing a driving force to perform a reciprocating motion or a rotational motion in the longitudinal direction of the dust collecting electrode (121), and a second driving means for providing a driving force for driving the spraying angle of the cleaning liquid sprayed from the cleaning nozzle (151) and the rotation of the cleaning nozzle (151) in at least one direction, and the first driving means and the second driving means may include a receiving means for receiving an external power source, a processor, a motor, a gear module for converting the rotational force of the motor into a motional force that enables the cleaning nozzle (151) to move up and down or rotate.

[0072] As an example, referring to FIG. 9, in FIG. 9 (a), as an example of cleaning for a plate-type dust collecting electrode (121), an example is shown in which a moving body of a cleaning module (15) is driven to move up and down along the longitudinal direction of the dust collecting electrode (121) by a first driving means, and a spraying angle of a cleaning nozzle (151) provided on a side of the moving body is adjusted by a second driving means to spray a cleaning solution on the inner surface of the dust collecting electrode (121) where foreign substances are collected.

[0073] In addition, as another embodiment, in (b) of FIG. 9, a first driving means drives the moving body of the washing module (15) to move up and down along the length direction of the dust collecting electrode (121), and a washing nozzle (151) is provided at the lower part of the moving body as a spiral nozzle, and a second driving means provides driving force to the washing nozzle (151) provided as a spiral nozzle to rotate and spray the washing liquid.

[0074] In addition, as another embodiment, in (c) of FIG. 9, as an example of cleaning for a cylindrical dust collecting electrode (121), it can be understood that an embodiment is shown in which the moving body of the cleaning module (15) is driven to move up and down along the longitudinal direction of the dust collecting electrode (121) by the first driving means, and the spraying angle of the cleaning nozzle (151) provided on the side of the moving body is adjusted by the second driving means to spray the cleaning solution on the inner surface of the dust collecting electrode (121) where foreign substances are collected.

[0075] In addition, in (d) of FIG. 9, as an example of cleaning for a cylindrical dust collecting electrode (121), it can be understood that an embodiment is shown in which a moving body of a cleaning module (15) is driven to move up and down along the longitudinal direction of the dust collecting electrode (121) by a first driving means, a cleaning nozzle (151) is provided at the lower part of the moving body as a spiral nozzle, and a second driving means provides driving force to the cleaning nozzle (151) provided as a spiral nozzle to rotate and spray a cleaning solution.

[0076] That is, in the present invention, the cleaning nozzle (151) is made to enter the inside of the dust collecting electrode (121) provided in a plate shape or a cylinder shape by the first driving means and the second driving means described above, and the cleaning liquid ejected from the cleaning nozzle (151) is sprayed evenly and over a wide range inside the dust collecting electrode (121), thereby enabling the cleaning liquid to be sprayed more evenly on the dust collecting electrode (121) compared to a cleaning nozzle that sprays the cleaning liquid in a fixed direction, thereby increasing the dust collecting efficiency and increasing the maintenance efficiency of the dust collecting electrode (121).

[0077] Meanwhile, in the embodiment of FIG. 9 described above, the embodiment is limited to a wet cleaning-based cleaning module using a cleaning solution as the cleaning module (15), but in another embodiment of the present invention, a shaking type dedusting module and an air blowing type dedusting module may be provided as modules that remove contaminants in a dust collecting electrode without using a cleaning solution.

[0078] Specifically, in the present invention, the first support means (1210) supporting the dust collecting electrode (121) is provided with an elastic body such as rubber, urethane, etc., and as schematically illustrated in (A) of FIG. 10, the dust collecting electrode (121) and the first support means (1210) are vibrated by a vibration-type dust removal module (15') that provides up and down vibration along the longitudinal direction of the dust collecting electrode (121) to the lower side of the first support means (1210), thereby removing contaminants remaining inside the dust collecting electrode (121) by causing them to be removed (off stream).

[0079] Also, as another example of a vibration type dust removal module (15'), referring to (B) of FIG. 10, in the present invention, the first support means (1210) supporting the dust collecting electrode (121) is provided with an elastic body such as rubber, urethane, etc., as described above, and by the vibration type dust removal module (15') that applies horizontal vibration in a direction perpendicular to the longitudinal direction of the dust collecting electrode (121) by holding the first support means (1210), the contaminants adsorbed on the inner surface of the dust collecting electrode (121) can be removed by losing the adsorption force due to the applied vibration.

[0080] Meanwhile, the air injection type dedusting module described above includes a compressed air tank that generates compressed air, a supply line that supplies compressed air from the compressed air tank, and an air injection nozzle that injects the compressed air supplied through the supply line.

[0081] At this time, the air spray nozzle described above further includes a third driving means for providing a driving force to perform a reciprocating motion or a rotational motion in the longitudinal direction of the dust collecting electrode (121), and a fourth driving means for providing a driving force to rotate the air spray nozzle that sprays compressed air in at least one direction, and the third and fourth driving means may include a receiving means for receiving an external power source, a processor, a motor, a gear module for converting the rotational force of the motor into a motional force that enables the air spray nozzle to move up and down or rotate.

[0082] As an example, the air injection type dust removal module can move up and down along the longitudinal direction of the dust collecting electrode (121) by the third driving means, and the spray angle of the air injection nozzle provided on the side of the moving body is adjusted by the fourth driving means, and the air injection nozzle can spray compressed air toward the contaminants remaining inside the dust collecting electrode (121), thereby causing the contaminants adsorbed on the inner surface of the dust collecting electrode (121) to lose their adsorption force by the applied compressed air, so that they can be removed.

[0083] In addition, as another embodiment, the air injection type dust removal module described above may be configured to install an air injection device on the upper side of the dust collection electrode (121) to spray compressed air in a surface unit like an air curtain, thereby removing contaminants remaining on the dust collection electrode (121), but the present invention is not limited thereto.

[0084] Meanwhile, a dedusting module including at least one of the vibration-type dedusting module and the air-jet-type dedusting module described above may be provided for each first support means (1210), or one dedusting module may be provided with driving force by a separate driving means to sequentially move each dust collecting electrode (121) and remove contaminants from the inside of the dust collecting electrode (121) by vibration or compressed air, but the present invention is not limited thereto.

[0085] In addition, although not explicitly shown in the attached drawing, the waste cleaning fluid generated by the performance of the function of the aforementioned cleaning module requires separate treatment. Accordingly, in the present invention, the cleaning fluid (i.e., waste cleaning fluid) sprayed from the cleaning nozzle of the cleaning module and used to clean the dust collecting electrode (121) is transferred to one or more waste cleaning fluid storage containers through a drop point or a path formed at the drop point, thereby increasing the convenience of discharging the waste cleaning fluid.

[0086] Meanwhile, the system (10) of the present invention includes, as a main component, an exhaust hood (131) for drawing in air whose temperature has increased due to heat generated in an indoor space, a third duct (D3) connected to the aforementioned exhaust hood (131), and an exhaust fan (130) connected to the aforementioned third duct (D3), thereby including an exhaust unit (13) for exhausting the air in the indoor space to the outside.

[0087] As a preferred embodiment, the above-described exhaust hood (131) may be provided in each area where a heat corridor of an indoor space is formed, and may be provided one or more times.

[0088] At this time, the heat corridor described above can be understood as a concept of an area where hot air that has cooled a server is discharged according to the arrangement of rack rows in an indoor space such as a base station, and in the present invention, an exhaust hood (131) is installed in each area corresponding to such a heat corridor so as to quickly exhaust indoor air with a raised temperature, thereby increasing the efficiency of controlling indoor temperature.

[0089] In addition, in the present invention, a damper (or louver) may be installed in a duct including at least one of the first duct (D1) and the second duct (D2) described above, so as to control the amount of outside air supplied to the indoor space by the damper. It can be understood that the above-described damper controls the amount of outside air supplied to the indoor space by adjusting the degree of opening of the blades of the damper based on the area of ​​the indoor space described later and the detected temperature.

[0090] In addition, the present invention includes a main power supply unit that supplies power for driving a configuration including the aforementioned external air supply unit (11), dust collection unit (12), and exhaust unit (13), and, in preparation for a situation where a power outage or problem occurs in the main power supply unit, an emergency power supply unit based on an UPS (Uninterrupted Power Supply) that converts DC power stored in a storage battery into AC power and supplies emergency power to the configuration including the external air supply unit (11), dust collection unit (12), and exhaust unit (13) is further included.

[0091] That is, the present invention includes an emergency power supply unit based on a reserve battery, so that even in a situation where a power supply is difficult due to a problem such as a power outage, power stored in the battery is used to supply power to the main components constituting the system (10) of the present invention, thereby maintaining cooling in an indoor space with a lot of heat emission such as a base station, thereby providing the effect of preventing fire caused by overheating, etc.

[0092] Meanwhile, the cooling system (10) for an indoor space using outside air may have an installation structure as shown in FIGS. 5 and 6 when installed on a single floor, but may have an installation structure as shown in FIG. 7 for more efficient outside air supply and internal exhaust when installed in a multi-story building.

[0093] Specifically, in the case where there are multiple indoor spaces to be air-conditioned and the multiple indoor spaces exist on different floors in a building, the cooling system (10) for an indoor space using outside air may be configured such that an outside air supply unit (11), a dust collection unit (12), and an exhaust unit (13) are installed in an indoor space or an outdoor space (preferably a rooftop), and a second duct (D2) connected to the dust collection unit (12) is extended to have a branched line to supply dust-treated outside air to the indoor space of each floor.

[0094] As an example, in the example of FIG. 7, an example of a building consisting of three floors and a rooftop is shown, and as described above, it can be confirmed that the second duct (D2) forms a branched line extending from the outdoor dust collection unit (12) to the indoor space of each floor.

[0095] In addition, in the case of the third duct (D3) that functions to discharge the indoor space's exhaust air to the outside, the exhaust air sucked in each indoor space is collected and exhausted to the outdoor exhaust unit (13), and the structure of this exhaust line can also be seen with reference to the embodiment of FIG. 7.

[0096] Meanwhile, the computing device of the present invention collects information on the area of ​​each indoor space and information on the indoor temperature detected by a temperature sensor installed in each indoor space, and the computing device controls the blade adjustment angle of the damper based on the area of ​​each indoor space and the real-time temperature detected in each indoor space, thereby varying the amount of outside air introduced into the indoor space, thereby enabling different cooling conditions to be set, and thereby enabling more efficient cooling control for each indoor space to be performed.

[0097] In one embodiment, when the temperature of an indoor space is detected to exceed a preset threshold temperature (e.g., 25 degrees), the computing device may set the blades of the damper to a maximum angle (i.e., set to a fully open angle) to increase the amount of outside air supplied, thereby rapidly circulating the air in the indoor space, thereby increasing cooling efficiency.

[0098] In another embodiment, if the temperature of an indoor space is detected to be lower than a preset threshold temperature, the computing device may adjust the blade angle of the damper, which was set to the maximum angle, downward, i.e., adjust the blade angle of the damper to be smaller, so that the indoor temperature is maintained at an appropriate level. That is, in the present invention, the blade angle of the damper can be variably controlled according to the indoor temperature detected in the indoor space, and the present invention is not limited thereto.

[0099] In addition, as another embodiment, the present invention further includes a humidity sensor in addition to a temperature sensor to measure the enthalpy of an indoor space and the enthalpy of the outdoor air, and when the indoor enthalpy is set to be higher than the outdoor enthalpy, the blades of the damper are set to the maximum angle to maximize the supply of outdoor air, thereby cooling the indoor space based on enthalpy control. This can be understood as a means for resolving the problem that the cooling load may increase due to latent heat when controlling cooling based on simple temperature, since humidity is not taken into consideration.

[0100] Preferably, the temperature and humidity sensor for measuring the enthalpy of the indoor space may be installed in an area adjacent to the exhaust hood, and the temperature and humidity sensor for measuring the enthalpy of the outside air may be installed in an area of ​​the first duct (D1) or the second duct (D2).

[0101] In a comprehensive review, according to the present invention described above, in providing a cooling system installed in an indoor space with a lot of heat emission, such as a base station, a server data room, or a data storage room, the present invention can reduce power consumption by bringing in outside air into the room and using it to lower the indoor temperature, thereby expecting a reduction in cooling costs.

[0102] In addition, according to one embodiment of the present invention, when outside air is simply introduced into a room, foreign substances such as dust contained in the outside air may have a negative effect on equipment within the base station and cause indoor space to be polluted. Therefore, by introducing outside air that has been dust-collected into the room so that clean outside air can be supplied to the indoor space, the above problem can be solved and the cooling efficiency of the indoor space can be maximized.

[0103] In addition, according to one embodiment of the present invention, by performing electrostatic precipitation by applying a micro pulse voltage to a discharge electrode by MPS, there is an effect that the amount of ozone generated during the dust collection process can be significantly reduced.

[0104] Although the embodiments have been described with limited examples and drawings, those skilled in the art will appreciate that various modifications and variations can be made from the above description.

For example, the processing device may include multiple processors, or a processor and a controller. Other processing configurations, such as parallel processors, are also possible.
