1 TARIFF A FILTER REGENERATION Technical Area The invention describes a dust filter used in air conditioners that has been modified to trap dust and odors. It is related to regeneration. State of the Art Increased industrial activity in recent years has led to a significant deterioration in indoor air quality due to particulate matter (PEP) 5. concentrations of particulate matter (PM) and volatile organic compounds (VOCs) considered safe This has caused the limit values to be exceeded. This situation poses a threat to human health. This has become the case. In indoor air purification systems, various methods are used to capture PMs and VOCs. Filters are used. These filtration technologies target the area without requiring a separate device. The components are also being adapted to air conditioners in a way that will allow them to capture high performance. It has begun. Current air conditioners generally use two types of filters. The one located on the outermost part of the suction line... Area dust filters are used to trap larger particles such as pollen. Smaller particles can also be filtered out. To remove PMs (pressure-sensitive particles), anti-allergen filters are used, placed below the dust filter. This 15 Filters include HEPA, electrostatic, and intense dielectric (IFD) filters. However, current anti-allergen filters have some disadvantages. HEPA filters require high pressure. due to problems such as degradation, short lifespan (approximately 6 months), loud noise, and disposable nature. They are not preferred in air conditioners. Electrostatic filters, on the other hand, have a short lifespan and are prone to condensation. It has problems such as performance loss and disposable characteristics. IFD filters, on the other hand, require an additional power unit 20. This necessitates high energy consumption, which leads to problems such as fire risk. Activated carbon filters are commonly used for VOC removal, but these filters have a short lifespan. Due to reasons such as its non-selective retention and high pressure drop, it is rarely preferred in air conditioners. Therefore, a high-performance 25 that effectively cleans PM and VOCs is needed. A filter material is needed. Aerogels, with their advantages such as high pore volume, large surface area and low density, have become the latest... Aerogels have started to attract attention as filter materials in recent years. Aerogels are recyclable bio-based. manufacturability from materials, ability to capture small particles with high efficiency, and again 30 2 Due to their usability properties, they are used in PM filtration. Additionally, aerogels... It can be synthesized from various inorganic, organic, or hybrid materials. Metal organic frameworks (MOFs) have come to the forefront in recent years for VOC removal. MOFs, High surface area, adjustable pore size, and selective odor molecule retention capabilities. 5 This is noteworthy. Furthermore, MOFs contain metal ions with antibacterial properties. It includes. What distinguishes aerogels and MOFs from other filtration technologies is their regeneration. These are its capabilities. Regeneration involves cleaning the filters by applying heat or washing them with water. 10 And this means they become reusable. Most existing filters have a disposable feature. It has this feature, which means additional costs and inconvenience for users. It is regenerable. Automatic regeneration is not yet widespread in filters, and there is no application for it in air conditioning. It is not available. Filters with regeneration capability are located where the user can remove them. It needs to be removed, regenerated, and then reinstalled. 15 For example, IFD filters must be flushed with water for regeneration and completely cleaned before being reinstalled. They must be dried. Filters for which heat regeneration is recommended should be dried at high temperatures, such as in an oven. They should be left in their environment for 1-2 hours, which can be costly. The previous technique describes the use of aerogels as filters. For example, CN211411357U 20 Utility Model application number [number] describes a graphene aerogel filter structure. A graphene aerogel plate is placed inside a porous film between two frames. It is compressed to create a filter.

The goal is to create an air conditioner that enables regeneration. 5 Another aim of the invention is to prevent a decrease in efficiency when the filter comes into contact with water due to condensation. The goal is to create an air conditioner that can be used for extended periods without being switched on. Another purpose of the invention is to provide long-term waste management through its low energy requirement and regeneration capability. an air conditioner containing an aerogel and / or MOF coated filter that can be reused repeatedly without forming a new one. to accomplish. 10 Another purpose of the invention is disassembly, washing, high-temperature drying, and recharging. The goal is to create an air conditioning system that eliminates problems like these. Another purpose of the invention is to create a disposable electrostatic filter that can be removed and washed, dried, and recharged. It has shown a significantly superior feature compared to the IFD filter, which is regenerated through steps such as these. 15 It has been proven that the filter can be regenerated on the air conditioner without causing any inconvenience to the user. It also differs from other filter and regeneration methods in that it can be used in various ways. 20 4 Detailed Description of the Invention The subject of the invention, the air conditioner (1), will have an air intake duct (3), and will remain in line with the air intake duct (3). at least one filter structure (4), at least one evaporator (5), at least one sensor positioned in this way (6), at least one fan (7), at least one motor (8) connected to fan (7) and driving fan (7), to fan (7) At least one control unit (9) and one air outlet duct (10) configured to give commands 5 includes. In one application of the invention, the filter structure (4); the front and back surfaces of the plastic component They are coated with a filter. This creates a gap between the two filters. The subject of the invention is... In the gap formed between the two dust filters, the inner surfaces of the two dust filters facing each other contain silica. A filter structure coated with aerogel and MOF-199 particles by compression method 10 It is an air conditioner in which regeneration is provided automatically (1). The subject of the invention is the air conditioner (1), an air intake duct (3) and the conditioning of the air taken from the environment. Equipped with an outlet channel (10) that allows it to be returned to the environment (by heating or cooling). an indoor unit (2); in the indoor unit (2) the air inlet duct (3) will remain in line with the direction of (3) 15 located in the ventilation path between the air inlet duct (3) and the air outlet duct (10). a filter installed and catching dust and odor molecules in the indoor unit (2) air its structure (4), a fan (7) that directs the air in the indoor unit (2), to the fan (7) connected and driving a fan motor (8) to rotate the fan (7); and a filter configured to ensure the regeneration of its structure (4), in the indoor unit (2) 20 To ensure that the directed hot air is conveyed to the filter structure (4) the motor (8) It includes a control unit (9) that gives the command to reverse the direction of rotation of the fan (7). This eliminates the need for currently used disposable electrostatic filters and filters that can be removed by the user. It is significantly superior to filters that are regenerated through steps such as washing, drying, and charging. 25 showing a feature and filter structure (4) on the air conditioner (1) without bothering the user. Regeneration ensures its reusability. In one application of the invention, the air conditioner indoor unit (2) takes air from the environment through the air intake duct (3) where the air is conditioned (by heating or cooling) and then released back into the environment. It is the main body group through which the conditioned air in the indoor unit (2) is circulated; air outlet duct (10) It is released into the external environment via this means. 30 5 In one application of the invention, the air conditioning indoor unit (2) is where the air taken from the environment is conditioned. (by heating or cooling) a small evaporator (5) and located on the evaporator (5) It contains at least one sensor (6). In one application of the invention, the air conditioner (1) has at least one sensor (6) measuring the temperature of the evaporator (5) and 5 A control unit that communicates with the motor (8) to decide the direction of rotation of the fan (7). (9) includes. In one application of the invention, the fan (7) can operate in both forward and reverse directions. The fan (7) in the forward direction It is a positive pressure pump that blows outwards when it is working. The fan (7) is in the opposite direction. While working, the air circulating inside the indoor unit (2) is filtered by the fan (7), motor (8) and damper system. It is directed towards its structure (4). It operates as a negative pressure pump. 10 In the air conditioner (1) that is the subject of the invention, the filter configuration (4) will be such that it is aligned with the suction line of the air conditioner (1). is installed. When the air conditioner (1) starts working, the filter structure (4) removes particles in the air and It continues its function by trapping odor molecules. After a certain period of time, the filter... The pores of the filters in the structure (4) start to fill up. For this reason, the air conditioner (1) and to ensure the continuity of the filter structure (4) used in the air conditioner (1) and 15 In order to extend its lifespan, the filter structure (4) needs to be regenerated. In this invention regeneration; the filter structure (4) with temperature and air flow, surface and pores by removing adhering particulate matter and odor molecules again It means that it becomes available for use. In one application of the invention, the air conditioner (1) includes a regeneration mode (11). The user can select a specific 20 By activating the regeneration mode (11) of the air conditioner (1) at intervals, the air conditioner temperature is set beforehand. the temperature is raised to a specified value and the hot air circulating in the indoor unit is directed by the fan. (7) being directed onto the filter structure (4) by reversing the normal working direction. and contact of hot air with the filter structure (4) for a predetermined period of time. By performing this operation, the filter is regenerated. 25 In one application of the invention, the control unit (9) activates the regeneration mode (11) When the evaporator (5) temperature, measured by sensor (6), reaches a predetermined value, the fan (7) is activated. By giving the command, the fan (7) rotates in the full direction of its initial rotation for a predetermined period of time. This causes the fan (7) to rotate in the opposite direction, causing the air conditioner indoor unit (2) to rotate in the opposite direction. The hot air is passed through the filter structure (4). For filter regeneration, 30 After hot air is passed through the filter structure (4) for a specified period of time, the control 6 unit (9) gives a command to the motor (8) to stop and in this way the filter configuration (4) regeneration will be complete. In one application of the invention, the specified evaporator (5) temperature is 45 degrees. It is in the 60-degree range. This temperature range is the general safe operating zone for air conditioners. It is a temperature value that remains inside, and above this temperature value, the filter structure is 5 (4) It has been determined that it has started to deteriorate. In one application of the invention, the predetermined time for the regeneration process is between 45 and 90 minutes. It is within a minute range. In one application of the invention, the fan (7) is a radial fan. In one application of the invention, the air outlet duct (10) is 10 when the air conditioner (1) is in regeneration mode (11). It can be in a closed or open position. Filter configuration in an application of the invention (4) Regeneration is independent of the condition of the air outlet duct (10). Because the fan (7) is in the indoor unit (2) the air inside is brought to a certain temperature value and then from the control unit (9) By moving in the opposite direction with the incoming command, the hot air through the filter structure (4) It is based on the principle of transmission. 15 The direction of the arrows in Figure 2 indicates the direction of airflow, i.e., the forward movement of the fan (7). The air circulation path is shown. Air taken from the environment is conditioned (heated) or by cooling) through the air outlet duct (10) by following the air path shown in Figure 2. It is released into the environment. When regeneration mode (11) is activated, the fan (7) reverses. With this study, the direction of the arrows in Figure 3 indicates the direction of airflow, that is, the path of advancing air circulation. 20 It is shown. Due to the general structure of radial fans (7), the directed air flow is shown in Figure 3. The air flow rate in Figure 2 will not be at the same level. However, because the fan (7) is stationary Therefore, since there will be more negative pressure, without using an additional mechanism, the most An efficient and shortest-term regeneration process can be achieved. After the predetermined time for regeneration mode (11), the air conditioner (1) will again turn the fan (7) forward 25 It continues to operate by working in this direction, following the air circulation path shown in Figure 2.
