Description

Technology Field

[0001] The present invention relates to an air conditioning system for a building, and more specifically, to a heat exchange air conditioning system equipped with a heat exchanger for heat exchange between indoor and outdoor air, and a system for automatically cleaning a filter unit for removing dust from the air. Background Technology

[0003] In modern buildings, managing indoor air quality is essential for the health and comfort of occupants. Particularly as social concerns regarding fine and ultrafine dust increase, the importance of heat exchange ventilation systems—which minimize heat loss while circulating indoor and outdoor air—is becoming increasingly prominent. Heat exchangers are devices that enhance energy efficiency by exchanging heat between airflows as they exhaust indoor air and draw in outdoor air; recently, they are being widely installed in various types of buildings, including apartments, office buildings, and hospitals.

[0004] One of the key components of such air conditioning units is the filter section, which captures dust, pollen, and fine particles from the outside air. While the filter plays a crucial role in determining the cleanliness of the air entering the room, there is a problem in that dust accumulates on the filter surface over time, increasing airflow resistance and reducing filtration efficiency. If the filter becomes clogged, not only does the load on the blower increase, leading to higher energy consumption, but there are also limitations such as reduced heat exchange efficiency and deterioration of indoor air quality. Consequently, filters must be replaced or cleaned periodically; however, since the replacement cycle is generally short—ranging from one to three months depending on the usage environment—maintenance costs and effort are significant.

[0048] Below, the building air conditioning device of the present invention will be described in detail.

[0049] First, with reference to FIGS. 1 to 7, I will explain the prerequisite technology for explaining the technical features of the building air conditioning device of the present invention.

[0050] FIG. 1 is a block diagram for explaining an air conditioning system for a building according to a first embodiment, FIG. 2 is a perspective view showing an air conditioning system for a building according to FIG. 1, and FIG. 3 is a plan view showing the interior of FIG. 2.

[0051] Referring to FIGS. 1 to 3, the air conditioning device for a building according to the present invention is described as follows: the air conditioning device for a building includes a heat exchanger (10) and a heat exchanger control means including a controller (C) that measures indoor temperature and humidity, fine dust and ultrafine dust in real time and operates the heat exchanger when the measured value exceeds a pre-stored threshold.

[0052] The heat exchanger (10) includes a case (11), an intake port (12, 13), an exhaust port (14, 15), a heat exchange section (16), a vibration absorbing member (17), and a blower (20).

[0053] A bracket or similar device may be attached to the outside of the case (11) for ease of installation. The case (11) may have a receiving section (111) that accommodates a heat exchanger (16), a vibration absorbing member (17), and a blower (20) inside, and a plurality of communication holes communicating with the outside of the receiving section (111) and the case (11) may each have an intake port (12, 13) and an exhaust port (14, 15) connected thereto.

[0054] The intake ports (12, 13) can draw indoor air into the case (11) and discharge it to the outside. The intake ports (12, 13) may include an indoor air intake connection part (12) in one of the communication holes and an intake air discharge part (13) in a communication hole diagonally opposite to the indoor air intake connection part (12).

[0055] The exhaust port (14, 15) can draw in outdoor air into the case (11) and supply it to the indoor space. The exhaust port (14, 15) includes an intake air discharge section (15) through which outdoor air passes through a heat exchange section (16) and is discharged into the indoor space via an outdoor air intake connection section (14) that draws in outdoor air by the operation of a blower.

[0056] For example, the external air intake connection (14) is located near the intake air discharge (15) and is provided in a communication hole opposite the intake air discharge (13), and the intake air discharge (15) may be provided in a communication hole opposite the indoor air intake connection (12) diagonally opposite the external air intake connection (14).

[0057] The heat exchanger (16) can exchange heat between indoor air moving through the intake port and outdoor air moving through the exhaust port. The heat exchanger (16) can exchange heat with outdoor air passing through the exhaust port (14, 15) and air introduced through the intake port (12, 13) between the intake port (12, 13) and the exhaust port (14, 15).

[0058] The heat exchanger (16) forms a bypass path to allow indoor air sucked into the indoor air intake connection (12) to bypass and be discharged to the intake air discharge (13), and can be equipped with a heat exchanger.

[0059] According to this, the heat exchanger (16) is a known technology in which the indoor air path and the outdoor air path intersect at the heat exchanger element, allowing the indoor air and the outdoor air to exchange heat with each other, so a detailed description thereof will be omitted.

[0060] The vibration absorbing member (17) can absorb vibrations generated from the heat exchanger (16) and the blower. The vibration absorbing member (17) is lightweight and has excellent thermal insulation, soundproofing, and cushioning properties, so it can maintain the thermal insulation inside the heat exchanger (10) and reduce noise generated from the blower (20), etc. Additionally, it can be provided with expanded polystyrene (EPS) to protect the components of the heat exchanger (10) from external impacts and improve durability.

[0061] The vibration absorbing member (17) may be provided on the upper and lower sides of the case (11), respectively, and may surround the blower (20). The vibration absorbing member (17) may be provided on the inner side of the case (11) to shield the case (11) and reduce noise.

[0062] The blower (20) can blow air into the intake port and the exhaust port, respectively. For example, the blower (20) includes an intake air blower in close proximity to the intake air discharge port (12) and an exhaust air blower in close proximity to the exhaust air discharge port (15) in the receiving portion (111).

[0063] Multiple heat exchanger control means may be provided indoors according to user settings. The heat exchanger control means may include a temperature and humidity measuring sensor (T, H) for measuring indoor temperature and humidity, a fine dust measuring sensor (D) and an ultrafine dust measuring sensor (MD) for measuring fine dust and ultrafine dust, a carbon dioxide detection sensor (CD) for measuring indoor carbon dioxide concentration, and a carbon monoxide detection sensor (CM) for detecting carbon monoxide concentration. The heat exchanger control means may provide information measured by each to a controller (C).

[0064] The controller (C) may include a communication unit, an interface, and an inverter, and can control the overall operation of the heat exchanger (10).

[0065] For example, the controller (C) can be directly connected to the heat exchanger (10) through a communication unit or communicated with the building's central control system to centrally control the heat exchanger (10). Additionally, the controller (C) may include a user interface or a receiver, allowing the user to directly control the heat exchanger (10) via a remote control or the like.

[0066] The controller (C) may be a monitor capable of monitoring, a mobile device, a tablet PC, etc., and is linked with an external server (S) to receive temperature and humidity information (THI) from the external server (S). For the convenience of explanation, it is described here as a tablet PC and an external server (S) being linked with each other.

[0067] The controller (C) may be a control unit that controls the heat exchanger (10) by comparing the data received from the heat exchanger control means with each preset threshold value.

[0068] The controller (C) receives data on the measurement results of each sensor and receives data on temperature and humidity information and dust information, and if any one or more of the preset temperature and humidity, fine dust, ultrafine dust, carbon dioxide concentration, and carbon monoxide concentration are above a preset threshold, it can switch to a wake-up mode and operate the heat exchanger (10).

[0070] In addition, the controller (C) receives data on the measurement results of each sensor and, if the preset temperature and humidity, fine dust, ultrafine dust, carbon dioxide, and carbon monoxide concentrations are below a preset threshold, switches to sleep mode to stop the operation of the heat exchanger (10) and switch to an idle state. Therefore, it is possible to detect operation in a standby state and save power.

[0071] For example, according to a building's air conditioning system, indoor temperature, humidity, fine dust, ultrafine dust, carbon dioxide, and carbon monoxide are measured in real time. If a set threshold is exceeded, the heat exchanger operates immediately to manage indoor air quality in real time. Furthermore, it enables the switching of the heat exchanger between sleep and wake-up modes and allows for efficient management of heating and cooling energy, thereby improving energy efficiency. Additionally, it can be easily integrated with smart home systems or IoT-based HVAC management systems by linking with external servers, mobile devices, and tablet PCs. Moreover, by comparing external weather, indoor air quality, temperature, and humidity in real time to maintain comfortable indoor air at all times, it enhances user convenience.

[0072] FIG. 4 is a diagram showing a connecting tube in a longitudinal cross-section according to a second embodiment, FIG. 5 is a diagram showing the air flow control means of FIG. 4, FIG. 6 is a diagram showing the operation of FIG. 5, and FIG. 7 is a diagram showing the dust suction part of FIG. 5.

[0073] Referring to FIGS. 4 to 7, the air conditioning device for a building according to the present invention is described as follows: the air conditioning device for a building includes a connecting tube (30) through which external air moves between an intake air discharge section (15) and a blower (20).

[0074] The connecting tube (30) is a passage that guides outside air into the room through an exhaust air blower, and is connected to the exhaust air blower on one side and to the intake air discharge part (15) on the other side so that outside air can move.

[0075] An air purification means (40) may be provided to selectively remove foreign substances, namely fine dust and ultrafine dust, and moisture moving along the passage of the connecting tube (30) and to purify the air.

[0076] The air purification means (40) may be sequentially equipped with a dust collection unit (41), a moisture removal unit (42), and an air purification filter (43) in the direction in which air moves into the room.

[0077] The dust collection unit (41) can remove fine dust and ultrafine dust from the outside air that has passed through the heat exchange unit (16). The dust collection unit (41) is equipped with an electrostatic filter and can generate electrostatic charge in the filter by the operation of the controller (C). Alternatively, the dust collection unit (41) may be equipped with a HEPA filter (High-Efficiency Particulate Air Filter).

[0078] The dust collection unit (41) is equipped with a pre-filter and an electrostatic filter in sequence so that large dust can be removed first, thereby reducing the load applied to the electrostatic filter.

[0079] The moisture removal unit (42) can remove moisture from the air removed by the dust collection unit (41). The moisture removal unit (42) can remove moisture from the air by heating it with a heating wire, a moisture removal mesh connected to a ceramic heater, or an infrared lamp, and supply dry air into the room. Here, it is described as being equipped with a heating wire.

[0080] For example, when ventilating indoor air, if the humidity value provided by the humidity sensor in the controller (C) is within a preset threshold, the controller (C) does not operate the moisture removal unit (42) in sleep mode, and if the humidity value is higher than the preset threshold, the controller (C) can operate the moisture removal unit (42) to supply dry air with moisture removed from the air into the room.

[0081] At this time, the temperature of the moisture removal unit (42) is adjusted according to the indoor humidity level to control the amount of moisture removed by the moisture removal unit (42), thereby maintaining the indoor humidity.

[0082] The air purification filter (43) can purify the air that has passed through the moisture removal unit (42). The air purification filter (43) may be equipped with either an activated carbon filter or a photocatalytic filter, and in this case, it is equipped with an activated carbon filter to remove odors or harmful gases remaining in the air from which moisture has been removed in the moisture removal unit (42), thereby removing bad odors and chemical substances.

[0083] Additionally, the connecting tube (30) includes a dust suction part (50) that collects dust filtered from the dust collection part (41), and an air flow control means (60) that controls the flow rate of air moving along the passage of the connecting tube (30).

[0084] Additionally, the dust suction unit (50) includes a dust storage tank (51) and a dust blower fan (52), and can be controlled by a controller (C).

[0085] The dust storage tank (51) can store dust filtered through the dust collection unit (41) on the upper and lower sides of the connecting tube (30). The dust storage tank (51) is provided on the upper and lower sides of the connecting tube (30), respectively, and is connected through a dust passage hole (not shown in the drawing) formed in the connecting tube (30), allowing dust within the connecting tube (30) to move.

[0086] A dust blower fan (52) is provided in the dust storage tank (51) between the dust storage tank (51) and the connecting tube (30) to blow dust into the dust storage tank (51). A dust blower fan (52) is provided on the dust passage hole to blow dust inside the connecting tube (30) into the dust storage tank (51).

[0087] Additionally, the connecting tube (30) may include an air flow control means (60) for controlling the flow rate of air.

[0088] The air flow control means (60) includes an opening / closing member (61) for controlling the amount of air supplied to the room, a motor (62), and an air blocking member (63), and can be controlled by a controller (C).

[0089] The opening / closing member (61) is provided in multiple numbers and can block air moving in the connecting tube (30). The opening / closing member (61) is connected by a hinge at the upper and lower sides inside the connecting tube (30), respectively, and a motor (62) connected to the hinge can drive the hinge at the upper and lower sides, respectively, to rotate the opening / closing member (61) around the hinge.

[0090] For example, if the user operates the ventilation of indoor air or if the indoor air quality is lower than a preset threshold, the user can operate the opening / closing member (61) toward the indoor side with a motor (62) to open it so that outdoor air moves.

[0091] At this time, the amount of air passing through can be controlled by adjusting the rotational speed of the motor (62) to control the amount of air supplied to the room according to the indoor air quality, thereby causing the opening / closing member (61) to form a predetermined angle.

[0092] Additionally, if the indoor air quality is within a threshold, the motor (62) can be operated in the reverse direction so that the opening / closing member (61) rotates in the opposite direction to the indoor side to close the inside of the connecting tube (30).

[0093] Meanwhile, the opening / closing member (61) can open and close the dust passage hole. Therefore, when the inside of the connecting tube (30) is closed by the opening / closing member (61), the dust passage hole is open, and when the inside of the connecting tube (30) is open, the dust passage hole is closed, so that dust inside the dust storage tank (51) can be prevented from escaping to the outside due to vortices generated while air is moving.

[0094] The air blocking member (63) can block the passage of air purified by the air purification filter (43) or block the inflow of indoor air.

[0095] For example, the air blocking member (63) rotates and opens around a hinge (not shown in the drawing) connected to the connecting tube (30) toward the indoor side by air pressure introduced through the exhaust air blower, and when the operation of the exhaust air blower stops, the air pressure is removed and it returns to its original position around the hinge, thereby shielding the inside of the connecting tube (30).

[0096] Here, the hinge is maintained in a closed state at all times by an elastic body (not shown), and the air blocking member (63) can be restored to its original state by an elastic body equipped to have an elastic force that allows rotation by air pressure from an exhaust air blower. Alternatively, it can be operated by a motor and rotated in the same way as the opening / closing member (61).

[0097] According to such a building air conditioning system, by utilizing a heat exchanger and sensors to detect and remove fine dust and ultrafine dust in real time upon intake of outside air, it is possible to effectively block external pollutants from entering the indoor space.

[0098] In addition, the indoor air is blocked from flowing into the connecting tube (30) by the air blocking member (63), thereby maintaining a constant indoor air quality when the heat exchanger is not operating, which has the effect of improving accuracy.

[0100] Hereinafter, with reference to FIGS. 8 to 11, another embodiment of the technical features of the building air conditioning device of the present invention will be described in detail.

[0101] FIG. 8 is a cross-sectional view of the connecting tube (30) in the longitudinal direction, FIG. 9 is a schematic perspective view of the filter section (1000), FIG. 10 is a view showing the state in which a rotation shaft (3300) is inserted into the filter section (1000), and FIG. 11 is a view showing the state in which a vibration shaft (2300) is inserted into the filter section (1000).

[0102] Here, the connecting tube (30) may be positioned between the external air intake connection (14) and the blower (20) as described above, but is not limited thereto, and may be positioned between the intake air discharge (15) and the heat exchanger (16) before the external air introduced through the intake air discharge (15) enters the heat exchanger (16). For example, the air conditioning device of the building of the present invention may include a filter unit (1000) that filters dust in the external air and is positioned inside the connecting tube (30), a rotating unit (3000) that rotates the filter unit (1000), and a vibrating unit (2000) that vibrates the filter unit (1000).

[0103] The filter unit (1000) can be placed inside the connecting tube (30) to perform the function of filtering dust from the outside air. The filter medium may be, for example, a HEPA (High Efficiency Particulate Air) filter, and its grade may be any one of H11, H13, H14, or ULPA U15 grades.

[0104] The shape of the filter section (1000) may be a cylindrical shape overall.

[0105] In addition, the filter unit (1000) may form a first insertion groove (H1) into which a rotation shaft (3300) to be described below is inserted, and a second insertion groove (H2) into which a vibration shaft (2300) to be described below is inserted.

[0106] The first insertion groove (H1) may be formed on the surface of the filter part (1000) facing the rotation axis (3300), and may be a groove that is a rectangular space.

[0107] The depth of the first insertion groove (H1) may have a sufficient length to allow the rotation shaft (3300) to be stably inserted, and furthermore, may be formed to a depth such that a gap is formed between the end of the rotation shaft (3300) and the filter part (1000) when the rotation shaft (3300) is inserted to the maximum extent.

[0108] This spacing is intended to allow the filter unit (1000) to easily vibrate in the vibration direction by the vibration unit (2000) to be described below.

[0109] The second insertion groove (H2) may be formed on the surface of the filter part (1000) facing the vibration shaft (2300), and may be formed around the entire perimeter of the surface of the filter part (1000) facing the vibration shaft (2300).

[0110] In addition, the depth of the second insertion groove (H2) may have a sufficient length to allow the vibration shaft (2300) to be stably inserted, and furthermore, it may be formed to a depth such that a gap space is formed between the end of the vibration shaft (2300) and the filter part (1000) when the vibration shaft (2300) is inserted to the maximum extent.

[0111] This clearance space is intended to minimize friction between the vibration shaft (2300) and the filter part (1000) when the filter part (1000) is rotated by the rotating part (3000) described below.

[0112] The rotating part (3000) can perform the function of rotating the filter part (1000). The rotating part (3000) can be positioned relatively inward compared to the filter part (1000).

[0113] The above-mentioned rotating part (3000) may include a rotating motor part (3100), a fixed shaft (3200) that fixes the rotating motor part (3100) at a predetermined position, a rotating shaft (3300) that is inserted into the filter part (1000) and rotated by the rotating motor part (3100), and a blade (3400) that is rotated by the rotating shaft (3300) and generates wind in a direction from the rotating motor part (3100) toward the filter part (1000) to remove dust attached to the filter part (1000).

[0114] The rotary motor part (3100) may be, for example, a DC brushless motor or a servo motor, and its rated voltage may be selected in the range of about 12V to 220V, and its rated output may be selected in the range of about 50W to 500W.

[0115] The above fixed shaft (3200) can perform the function of fixing the above rotary motor part (3100) at a predetermined position in the internal space of the above connecting tube (30), and its material may be stainless steel or aluminum alloy.

[0116] The above-mentioned rotating shaft (3300) is connected to the shaft of the above-mentioned rotating motor unit (3100) and can perform the function of transmitting rotational power to the above-mentioned filter unit (1000).

[0117] The above rotation axis (3300) can be rotated clockwise or counterclockwise based on a predetermined rotation center axis in the left and right directions, based on FIG. 8.

[0118] The above-mentioned rotating shaft (3300) may include a first rotating shaft (3310) extending from the motor part and a second rotating shaft (3320) inserted into the filter part (1000), and the first rotating shaft (3310) and the second rotating shaft (3320) may be formed integrally.

[0119] A blade (3400), which will be described below, may be mounted on the first rotation axis (3310) and may be cylindrical in shape.

[0120] The second rotation axis (3320) may have a rectangular shape corresponding to the shape of the first insertion groove (H1).

[0121] The blade (3400) can be mounted on the rotation axis (3300) and perform the function of generating air flow when rotated. The direction of air flow may be from the inside to the outside. The number of blades (3400) may be selected from, for example, a range of 3 to 6.

[0122] The rotating part (3000) may operate when the operation of the heat exchanger (100) is stopped and in an idle state. The rotating part (3000) may operate in a first mode and a second mode, the first mode may be a mode in which the filter part (1000) is rotated 90 degrees at a first speed to change the placement position of the filter part (1000), and the second mode may be a mode in which the filter part (1000) is rotated continuously for a predetermined time at a second speed faster than the first speed to remove dust attached to the filter part (1000).

[0123] In the first mode, the rotating part (3000) can rotate the filter part (1000) at a low speed. The first speed can be selected, for example, in the range of about 0.5 RPM to 2 RPM, and the rotation angle can be exactly 90 degrees. This low-speed rotation can prevent dust from accumulating intensively only in a specific area of ​​the filter surface by changing the placement position of the filter part (1000), and allow dust to adhere uniformly over the entire surface area of ​​the filter.

[0124] In the second mode, the rotating part (3000) can rotate the filter part (1000) at a high speed. The second speed can be selected, for example, in the range of about 1000 RPM to 3000 RPM, and the rotation time can be selected in the range of about 30 seconds to 180 seconds. Such high-speed rotation generates centrifugal force to move dust attached to the filter part (1000) to the outer edge of the filter, and at the same time, the dust can be separated from the filter surface by the strong airflow generated by the rotation of the blade (3400).

[0125] The above vibration unit (2000) can perform the function of vibrating the filter unit (1000). The vibration unit (2000) may be formed around the inner wall of the connecting tube (30) and may be arranged to surround at least a portion of the end of the filter unit (1000).

[0126] The above vibration unit (2000) may include a case unit (2100) forming a receiving space (P) that accommodates the end of the filter unit (1000), a vibration motor unit (2200) that causes vibration and is placed in the receiving space (P), a vibration shaft (2300) that is inserted into the filter unit (1000) and vibrates by the vibration motor unit (2200), and an elastic pressure unit (2400) that is connected to the case unit (2100) and elastically pressurizes the filter unit (1000) to prevent dust from entering the receiving space (P).

[0127] The above case part (2100) can be mounted on the inner wall of the connecting tube (30) and can form a receiving space (P) inside that can accommodate the vibration motor part (2200) and the vibration shaft (2300).

[0128] The vibration motor unit (2200) may be, for example, an electromagnetic vibrator, and its rated voltage may be selected in the range of about 12V to 220V, and its rated output may be selected in the range of about 20W to 150W. The frequency of the vibration generated by the vibration motor unit (2200) may be selected in the range of about 50Hz to 300Hz, and the vibration amplitude may be selected in the range of about ±1mm to ±5mm.

[0129] The above vibration shaft (2300) is connected to the shaft of the vibration motor unit (2200) and can perform the function of transmitting vibration to the filter unit (1000).

[0130] The above vibration shaft (2300) can vibrate in the left and right directions (vibration directions) based on FIG. 11.

[0131] The above vibration shaft (2300) may be provided with a first vibration shaft (2310) that extends from the vibration motor part (2200) and is inserted into the second insertion groove (H2) of the filter part (1000), and a second vibration shaft (2320) that protrudes in the vibration direction from the first vibration shaft (2310), and the first vibration shaft (2310) and the second vibration shaft (2320) may be formed integrally.

[0132] The second vibration shaft (2320) is inserted into the second insertion groove (H2) of the filter unit (1000) and can function to fix the position of the filter unit (1000) so that the filter unit (1000) is rotated by the rotation unit (3000) around a predetermined rotation center axis.

[0133] The elastic pressurizing member (2400) elastically pressurizes the filter member (1000), thereby minimizing the gap between the filter member (1000) and the case member (2100) even during vibration, so as to prevent dust from entering the receiving space (P). The elastic pressurizing member (2400) may include a first pressurizing member (2410), which is an elastic body and has one end connected to the case member (2100), and a second pressurizing member (2420), which is connected to the other end of the first pressurizing member (2410) and pressurizes the filter member (1000) by contacting the filter member (1000).

[0134] The second pressurizing member (2420) may overlap with the vibration shaft (2300) in the vibration direction to enhance sealing. Here, "overlap" may mean that the second pressurizing member (2420) overlaps with the vibration shaft (2300) by a certain length along the axial direction of the vibration shaft (2300) in the vibration direction. The overlap length may be selected, for example, in the range of about 10 mm to 50 mm. This overlap structure ensures that the second pressurizing member (2420) always maintains an overlapping state with the vibration shaft (2300) by a certain length even while the vibration shaft (2300) is vibrating, thereby effectively blocking dust from entering the receiving space (P).

[0135] The above vibration unit (2000) can operate in conjunction with the operating mode of the above rotation unit (3000). Specifically, the above vibration unit (2000) does not vibrate the filter unit (1000) when the above rotation unit (3000) is driven in the first mode, and vibrates the filter unit (1000) when the above rotation unit (3000) is driven in the second mode. Such coordinated control can increase energy efficiency and improve cleaning efficiency by maximizing the synergistic effect of rotation and vibration.

[0136] When the vibration unit (2000) is operated in the second mode, the vibration motor unit (2200) can automatically adjust the vibration frequency according to the rotational speed of the rotation unit (3000). For example, when the rotational speed of the rotation unit (3000) is in the range of about 1000 RPM to 1500 RPM, the vibration frequency may be about 100 Hz; when the rotational speed is in the range of about 1500 RPM to 2500 RPM, the vibration frequency may be about 150 Hz; and when the rotational speed is in the range of about 2500 RPM to 3000 RPM, the vibration frequency may be about 200 Hz. Such variable frequency control can avoid resonance between the rotational frequency and the vibration frequency and optimize cleaning efficiency.

[0137] When the rotating part (3000) and the vibrating part (2000) operate simultaneously, centrifugal force and impact force can act in combination on the filter part (1000). The centrifugal force can move large dust particles (e.g., 10 μm or larger) attached to the surface of the filter to the outer edge of the filter, the impact force can separate medium-sized dust particles (e.g., 1 μm to 10 μm) strongly adsorbed to the filter fibers by static electricity, and the airflow from the blade (3400) can remove fine dust particles (e.g., less than 1 μm) deeply embedded between the filter fibers. This triple composite cleaning mechanism can improve cleaning efficiency by about 30% to 50% compared to a single mechanism.

[0138] The air conditioning device of the building according to the present invention may further include a differential pressure sensor. The differential pressure sensor can measure the pressure difference between the inside and outside based on the filter unit (1000), and the measurement range may be, for example, about 0 Pa to 500 Pa, and the accuracy may be about ±2% FS.

[0140] Meanwhile, the building air conditioning device of the present invention can operate with the following process.

[0141] First, while the heat exchanger (100) is operating normally, the blower can draw in outside air through the connecting tube (30), pass it through the filter unit (1000) to remove dust, and then supply it to the room. During this process, dust may gradually accumulate in the filter unit (1000), and the differential pressure sensor can continuously monitor the pressure difference between the inside and outside based on the filter unit (1000).

[0142] When the operation of the heat exchanger (100) is stopped and it becomes idle, the controller (C) can analyze the pressure difference data measured from the differential pressure sensor to determine whether cleaning is necessary for the filter unit (1000) and to determine the cleaning mode. If the pressure difference is less than a predetermined first threshold value (e.g., 100 Pa), the controller (C) can operate the rotating unit (3000) in the first mode.

[0143] In the first mode, the rotary motor unit (3100) can be driven at a low speed (e.g., 0.5 RPM to 2 RPM) to rotate the rotary shaft (3300), and the rotary shaft (3300) can rotate the filter unit (1000) exactly 90 degrees. This 90-degree rotation can change the placement position of the filter unit (1000), thereby dispersing the area where dust accumulates intensively due to air flow and ensuring uniform wear across the entire surface area of ​​the filter. The operating time of the first mode can be selected in the range of about 5 seconds to 30 seconds, and the power consumption can be selected in the range of about 3W to 10W. In the first mode, the vibration unit (2000) may not operate, which can minimize energy consumption.

[0144] When the pressure difference is greater than or equal to the first threshold value, the controller (C) can operate the rotating part (3000) in the second mode. In the second mode, the rotating motor part (3100) can be driven at a high speed (e.g., 1000 RPM to 3000 RPM) to rotate the rotating shaft (3300), and the blade (3400) mounted on the rotating shaft (3300) can rotate at a high speed and generate a strong airflow. The speed of the airflow can be selected in the range of, for example, about 5 m / s to 20 m / s, and the airflow can separate dust attached to the filter part (1000) from the inside to the outside.

[0145] At the same time, when the rotating part (3000) operates in the second mode, the controller (C) can operate the vibration part (2000). The vibration motor part (2200) can vibrate the vibration shaft (2300), and the vibration shaft (2300) can transmit vibration to the filter part (1000). The frequency of the vibration can be selected, for example, in the range of about 100 Hz to 200 Hz, and the vibration amplitude can be selected in the range of about ±1 mm to ±5 mm. Such high-frequency vibration can apply vibrational force to the filter part (1000) to separate dust strongly adsorbed to the filter fiber by static electricity.

[0146] By operating the rotating part (3000) and the vibrating part (2000) simultaneously, centrifugal force, vibration force, and airflow can act in combination on the filter part (1000). The centrifugal force can move large dust particles to the outer edge of the filter, the vibration force can separate medium-sized dust particles from the filter fibers, and the airflow can remove fine dust particles from the filter surface. The separated dust can be moved from the inside outward by gravity and the airflow.

[0147] The operating time of the second mode may be variably adjusted according to the magnitude of the pressure difference. For example, if the pressure difference is about 100 Pa or more and less than 300 Pa, the operating time may be about 30 seconds, and if the pressure difference is about 300 Pa or more, the operating time may be about 180 seconds. The power consumption of the second mode may be selected in the range of about 80 W to 150 W.

[0148] After cleaning is completed, the controller (C) may stop the operation of the rotating part (3000) and the vibrating part (2000) and switch to standby mode. The differential pressure sensor may measure the pressure difference after cleaning to verify the cleaning effect, and if the cleaning effect is insufficient, the controller (C) may perform additional cleaning or generate an alarm to notify the user that a filter replacement is required.

[0150] Although the structure and features of the present invention have been described above based on embodiments according to the present invention, the present invention is not limited thereto, and it is obvious to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention; therefore, it is noted that such changes or modifications fall within the scope of the appended claims.
