Air purification modules, air conditioners, heat exchangers and air conditioning systems
[0001] This application claims priority to Chinese Patent Application No. 202422137115.7, filed on August 30, 2024; and Chinese Patent Application No. 202411219530.5, filed on August 30, 2024; Chinese Patent Application No. 202411219521.6, filed on August 30, 2024; and Chinese Patent Application No. 202422949134.X, filed on November 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This disclosure relates to the field of air purification technology, and in particular to an air purification module, an air conditioner, a total heat exchanger, and an air conditioning system. Background Technology
[0003] The deodorization technologies mainly rely on materials with adsorption properties, such as activated carbon, to physically adsorb odor substances in the air. The adsorption temperature has a significant impact on the adsorption effect of the adsorption material. The lower the adsorption temperature, the better the adsorption effect. The higher the temperature, the higher the kinetic energy of the odor molecules, making them more difficult to capture.
[0004] The adsorption materials in related technologies are mainly activated carbon and molecular sieves. During adsorption, the adsorbent is mainly placed in the adsorption area for adsorption at room temperature. The temperature of the adsorption material is not effectively controlled, which leads to the re-desorption of some substances with low boiling points, such as ammonia and hydrogen sulfide, after adsorption, producing secondary odor substances.
[0005] To achieve better adsorption, the thickness of the adsorption coating needs to be increased. However, using a thicker adsorption coating results in greater equipment resistance and higher energy consumption. Furthermore, at room temperature, the surface micropore size of adsorption materials such as activated carbon and molecular sieves is uncontrollable, thus lacking selectivity for odor gases and easily causing some odor gases to fail to be adsorbed, resulting in insufficient adsorption. After the adsorption material becomes saturated, it needs to be disassembled and placed in a specialized desorption and regeneration device for heated desorption, which is a cumbersome and inconvenient operation. Summary of the Invention
[0006] This invention aims to solve the problems of insufficient adsorption, poor adsorption effect, and inconvenient desorption operation.
[0007] According to some embodiments of this disclosure, an air purification module is provided, comprising: an adsorption substrate, wherein an adsorption coating is coated on the adsorption substrate, the adsorption coating being configured to adsorb and purify airflow passing through it; and a heat exchange component for heat exchange, mounted on the adsorption substrate, wherein a heat exchange channel for introducing a heat exchange medium is formed inside the heat exchange component, the heat exchange channel being configured to exchange heat with the adsorption coating through the heat exchange medium introduced therein to regulate the temperature of the adsorption coating.
[0008] The air purification module disclosed herein, by installing a heat exchange component on the adsorption substrate, allows for the introduction of refrigerant at different temperatures into the heat exchange component according to different usage conditions. During adsorption, a low-temperature refrigerant can be introduced to exchange heat with the adsorption coating on the adsorption substrate, cooling the adsorption coating and increasing the activity of the adsorbent within it, ensuring sufficient adsorption and improving adsorption performance. Alternatively, a high-temperature refrigerant can be introduced to exchange heat with the adsorption coating on the adsorption substrate, heating the adsorption coating to perform desorption and regeneration of the adsorption coating after adsorption saturation. This eliminates the need to place the entire device in a desorption heating device for desorption, making the desorption operation more convenient.
[0009] According to some embodiments of this disclosure, an air conditioner is provided, including: a housing; and a return air section and an air outlet section disposed on the housing; a heat exchange duct for circulating gas, wherein the gas exchanges heat within the heat exchange duct; an air supply device disposed within the heat exchange duct for driving the gas to flow within the heat exchange duct; and an air purification module assembled in the return air section, the air outlet section, or the duct.

Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.
[0053] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to."

Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.
[0054] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.
[0055] In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used.

[0057] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.
[0058] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.
[0059] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0061] The adsorption materials in related technologies are mainly activated carbon and molecular sieves. During adsorption, the adsorbent is mainly placed in the adsorption area for adsorption at room temperature. The temperature of the adsorption material is not effectively controlled, which leads to the re-desorption of some substances with low boiling points, such as ammonia and hydrogen sulfide, after adsorption, producing secondary odor substances.
[0062] To achieve better adsorption, the thickness of the adsorption coating needs to be increased. However, using a thicker adsorption coating results in greater equipment resistance and higher energy consumption. Furthermore, at room temperature, the surface micropore size of adsorption materials such as activated carbon and molecular sieves is uncontrollable, thus lacking selectivity for odor gases and easily causing some odor gases to fail to be adsorbed, resulting in insufficient adsorption. After the adsorption material becomes saturated, it needs to be disassembled and placed in a specialized desorption and regeneration device for heated desorption, which is a cumbersome and inconvenient operation.
[0063] To address the aforementioned issues, some embodiments of this disclosure provide an air purification module.
[0064] In some embodiments, as shown in Figures 1 and 2, the air purification module may include an adsorption substrate 211. An adsorption coating 212 may be coated on the adsorption substrate 211. The adsorption coating 212 is configured to adsorb and purify the airflow passing through it.
[0065] In some embodiments, as shown in Figures 1 and 2, the adsorption substrate 211 can be a carrier for the adsorption coating 212. The adsorption coating 212 is applied to the adsorption substrate 211 to achieve its corresponding adsorption function.
[0066] In some embodiments, as shown in Figures 1 and 2, the adsorption coating 212 applied to the adsorption substrate 211 can be applied to the outer surface of the adsorption substrate 211 or to the interior of the adsorption substrate 211.
[0067] In some embodiments, as shown in Figures 1 and 2, to ensure that the airflow passing through the adsorption substrate 211 is adsorbed and purified, the adsorption coating 212 applied to the adsorption substrate 211 can be configured to be located in the flow path of the airflow passing through the adsorption substrate 211. Thus, when the airflow passes through the adsorption substrate 211, it will inevitably pass through the adsorption coating 212, and the adsorption coating 212 can adsorb, deodorize, and purify the airflow.
[0068] In some embodiments, as shown in FIG2, the adsorption coating 212 can be an adsorption coating 212 composed of porous adsorption materials such as activated carbon, molecular sieves, or graphene. The surface of the adsorption coating 212 has micropores, through which the airflow passing through it can be adsorbed.
[0069] In some embodiments, the adsorption coating 212 is loaded with titanium dioxide and manganese-based catalysts. Titanium dioxide can undergo a photocatalytic oxidation reaction with ultraviolet light to generate a large number of hydroxyl radicals, thereby decomposing some odorous gases. At the same time, the manganese-based catalyst has a good decomposition effect on odorous substances such as aldehydes. Therefore, the purification effect of this deodorization device on odorous gases can be greatly improved.
[0070] In some embodiments, as shown in Figures 1 and 2, the air purification module may include a temperature regulating component 221. The temperature regulating component 221 may be mounted on the adsorption substrate 211. A heat exchange channel 2211 for introducing a heat exchange medium may be formed inside the temperature regulating component 221. The heat exchange channel 2211 inside the temperature regulating component 221 is mainly used for introducing a heat exchange medium, which is a refrigerant with a set temperature. The heat exchange channel 2211 may be configured to exchange heat with the adsorption coating 212 through the heat exchange medium introduced into it, thereby regulating the temperature of the adsorption coating 212. The temperature regulating component 221 mainly transfers energy and heat directly or indirectly through the heat exchange medium flowing inside the heat exchange channel 2211 and the adsorption coating 212.
[0071] By installing the temperature control component 221 onto the adsorption substrate, a direct connection between the temperature control component 221 and the adsorption substrate 211 is achieved. After the heat exchange medium is introduced into the heat exchange channel 2211 inside the temperature control component 221, it will exchange heat with the adsorption substrate 211 connected to the temperature control component 221, and indirectly exchange heat with the adsorption coating 212, thereby achieving temperature regulation of the adsorption coating 212.
[0072] In some embodiments, as shown in Figures 1 and 2, after a heat exchange medium is introduced into the temperature regulating component 221, the temperature regulating component 221 will directly contact the adsorption coating 212 and directly exchange heat with the adsorption coating 212 to regulate the temperature of the adsorption coating 212.
[0073] In some embodiments, as shown in Figures 1 and 2, by introducing heat exchange media of different temperatures into the heat exchange channel 2211 and the adsorption coating 212 for heat exchange, the function of heating or cooling the adsorption coating 212 can be realized.
[0074] In some embodiments, as shown in Figures 1 and 2, when a low-temperature heat exchange medium is introduced into the temperature regulating component 221, the low temperature of the heat exchange medium in the heat exchange channel 2211 causes it to exchange and absorb heat with the adsorption substrate 211, resulting in a decrease in the temperature of the adsorption substrate 211 and the adsorption coating 212. This decrease in temperature of the adsorption coating 212 makes it easier for the micropores on the surface of the adsorption coating 212 to capture volatile gas components in the air, thereby improving deodorization and purification efficiency.
[0075] In some embodiments, as shown in Figures 1 and 2, when a high-temperature heat exchange medium is introduced into the temperature control component 221, the high temperature of the heat exchange medium located in the heat exchange channel 2211 will release heat, thereby transferring heat to the adsorption substrate 211. The adsorption substrate 211 transfers heat to the adsorption coating 212 coated thereon, thereby raising the temperature of the adsorption coating 212. The increased temperature of the adsorption coating 212 causes the previously adsorbed odor gas components to volatilize again, thereby achieving the function of desorption and regeneration.
[0076] The air purification module has a temperature control component 221 installed on the adsorption substrate 211, which allows the refrigerant of different temperatures to be introduced into the temperature control component 221 according to different usage conditions.
[0077] For example, during adsorption, the adsorption coating 212 on the adsorption substrate 211 can be cooled by introducing a low-temperature refrigerant to exchange heat with it, thereby increasing the activity of the adsorbent in the adsorption coating 212, ensuring sufficient adsorption, and improving adsorption performance.
[0078] For example, the adsorption coating 212 on the adsorption substrate 211 can be heated by introducing a high-temperature refrigerant to exchange heat with it, thereby heating and desorbing the saturated adsorption coating 212 for regeneration. When desorption and regeneration are required, only a high-temperature refrigerant needs to be introduced into the temperature control component 221, eliminating the need to place the entire device in a desorption heating device, making the desorption operation more convenient. By introducing refrigerants of different temperatures into the temperature control component 221, the entire device can be quickly switched between adsorption and desorption / regeneration functions. Furthermore, desorption / regeneration can solve the adsorption saturation problem, extending the service life of the device and improving its reliability.
[0079] In some embodiments, as shown in Figures 1 and 2, the air purification module operates as follows: When the device performs the adsorption process, the odorous gas passes through the adsorption substrate 211 from the windward side. At this time, a heat exchange medium with a lower temperature flows through the temperature regulating component 221, which lowers the temperature of the adsorption substrate 211. At this time, the odorous gas has a higher temperature relative to the adsorption substrate 211. When the two meet, the molecules of the odorous gas with a higher temperature move and come into contact with the adsorption material with a lower temperature and are quickly captured.
[0080] Because the higher the temperature, the better the volatility of odorous gas molecules, and the lower the temperature, the greater the adsorption capacity of the adsorption coating 212. Therefore, when high-temperature odorous gas passes through the low-temperature adsorption coating 212, the odorous gas molecules inside are fully captured and intercepted by the adsorption material in the adsorption coating 212, resulting in sufficient adsorption, good adsorption effect, and the treated clean gas is discharged outward.
[0081] In some embodiments, as shown in Figures 1 and 2, as odorous gas molecules accumulate on the adsorption coating 212 of the adsorption substrate 211, the adsorption performance of the adsorption coating 212 gradually decreases. At this time, it is necessary to regenerate the adsorption coating 212 on the adsorption substrate 211 by reversing the airflow. At this time, clean gas passes through the adsorption substrate 211 from the leeward side. At this time, a medium with a higher temperature flows through the temperature regulating component 221, which raises the temperature of the adsorption substrate 211 and the temperature of the adsorption coating 212. The adsorbed odorous gas gradually volatilizes as the temperature rises and is discharged into the outdoor environment, thus completing the desorption.
[0082] In some embodiments, as shown in Figures 1 and 2, the adsorption substrate 211 may have thermal conductivity, which enables it to have good heat transfer and conduction effects, allowing for rapid heat exchange when a refrigerant is introduced into the heat exchange medium, thereby achieving rapid temperature regulation of the adsorption coating 212.
[0083] In some embodiments, as shown in Figures 1 and 2, the adsorption substrate 211 can be a metallic material such as copper or aluminum, or a ceramic material such as alumina or silicon nitride, as long as it has good heat transfer and thermal conductivity.
[0084] In some embodiments, as shown in Figures 1 and 2, an airflow channel 213 may be formed on the adsorption substrate 211. The airflow channel 213 is used for the flow of gas through the adsorption substrate 211.
[0085] In some embodiments, as shown in Figures 1 and 2, multiple airflow channels 213 can be provided. These multiple airflow channels 213 are evenly distributed throughout the adsorption substrate and penetrate the adsorption substrate. An adsorption coating 212 can be applied to the inner wall of each airflow channel 213. The airflow passing through the adsorption substrate 211 will pass through the airflow channels 213 that penetrate it. To achieve adsorption and purification of the airflow passing through the adsorption substrate 211, an adsorption coating 212 can be applied to the inner wall of the corresponding airflow channel 213.
[0086] By setting multiple airflow channels 213 and uniformly covering the adsorption substrate, the contact area between the adsorption coating 212 and the airflow can be increased, allowing the airflow to flow through the adsorption coating 212 in each airflow channel 213, thereby ensuring sufficient adsorption and purification of the airflow and improving the adsorption and purification effect of the airflow.
[0087] In some embodiments, as shown in FIG2, the airflow channel 213 is an airflow passage hole that penetrates the adsorption substrate along the airflow direction. The shape of the airflow passage hole can be honeycomb, circular, square or polygonal.
[0088] In some embodiments, as shown in FIG2, the adsorption matrix may include a matrix forming surface 214. Multiple matrix forming surfaces 214 may be provided, and the matrix forming surfaces 214 may be used to form the surfaces of the adsorption matrix 211.
[0089] In some embodiments, as shown in FIG2, at least one substrate forming surface 214 is located in the flow path of the airflow passing through the adsorption substrate 211. An adsorption coating 212 is applied to the substrate forming surface 214 located in the flow path. The adsorption coating 212 can be applied to the substrate forming surface 214, i.e., at least one surface of the adsorption substrate 211.
[0090] To ensure that the adsorption coating 212 can adsorb and purify the airflow flowing through the adsorption substrate 211, the adsorption coating 212 should be applied to the substrate surface 214 located in the airflow path. This ensures that the flowing airflow can pass through the adsorption coating 212 for adsorption and purification.
[0091] In some embodiments, as shown in FIG2, the substrate forming surface 214 located in the airflow path can be one or more surfaces. During installation, an adsorption coating 212 is applied to one or more surfaces accordingly.
[0092] In some embodiments, as shown in FIG3, the temperature regulating component 221 may be disposed in contact with the outer surface of the adsorption substrate 211. The temperature regulating component 221 is used to contact the adsorption substrate 211 and exchange heat directly or indirectly with the adsorption coating 212 to regulate the temperature of the adsorption coating 212.
[0093] In some embodiments, as shown in Figures 2 and 3, the temperature regulating component 221 can be attached to the substrate surface 214 of the adsorption substrate 211 coated with the adsorption coating 212. By directly attaching the temperature regulating component 221 to the adsorption coating 212, when the heat exchange medium flows into the temperature regulating component 221, the temperature regulating component 221 can directly exchange heat with the adsorption coating 212, thereby regulating the temperature of the adsorption coating 212.
[0094] In some embodiments, as shown in Figures 2 and 3, the temperature regulating component 221 can be attached to the substrate surface 214 of the adsorption substrate 211 where the adsorption coating 212 is not coated. When a refrigerant is introduced into the temperature regulating component 221, heat is exchanged between the temperature regulating component 221 and the adsorption substrate 211, and then transferred through the adsorption substrate 211 to the adsorption coating 212, thereby achieving temperature regulation of the adsorption coating 212.
[0095] In some embodiments, as shown in FIG3, the temperature regulating component 221 can be arranged inside the adsorption substrate. The temperature regulating component 221 can be bent along the length and / or width direction of the adsorption substrate. A heat exchange inlet 2215 and a heat exchange outlet 2216 can be formed at both ends of the temperature regulating component 221, respectively. By bending the temperature regulating component 221, a bent heat exchange channel 2211 can be formed inside the adsorption substrate 211, which can increase the contact area with the adsorption substrate 211 and improve the heat exchange efficiency.
[0096] In some embodiments, as shown in FIG3, the temperature regulating component 221 can be bent along the length direction of the adsorption substrate 211 to form multiple interconnected bent segments. A heat exchange inlet 2215 and a heat exchange outlet 2216 are formed at both ends of the temperature regulating component 221 for the inflow and outflow of refrigerant.
[0097] In some embodiments, as shown in FIG3, the temperature control component 221 can be bent along the width direction of the adsorption substrate to form multiple bent segments connected end to end.
[0098] In some embodiments, as shown in FIG3, the temperature regulating component 221 can be formed in two parts. One part is bent along the length direction of the adsorption substrate 211, and the other part is bent along the width direction of the adsorption substrate 211. The two parts are connected end-to-end, which can also achieve heat exchange.
[0099] In some embodiments, as shown in FIG1, the adsorption substrate 211 may include a first adsorption frame 2111. An installation space 2110 is formed inside the first adsorption frame 2111, extending through it.
[0100] In some embodiments, as shown in FIG1, the adsorption substrate 211 may include an adsorption member 2112 connected inside the first adsorption frame 2111. An airflow channel 213 is formed inside the adsorption member 2112.
[0101] In some embodiments, the adsorption member 2112 can be an adsorption substrate. The adsorption member 2112 can be sealed at the mounting space 2110 of the first adsorption frame 2111. The periphery of the adsorption member 2112 can be fixedly connected to the periphery of the first adsorption frame 2111.
[0102] In some embodiments, as shown in FIG1, the airflow channel 213 may be disposed through the adsorption substrate. An adsorption coating 212 is coated on the inner wall of the airflow channel 213 to adsorb and purify the airflow passing through the airflow channel 213.
[0103] By configuring the adsorption substrate as a first adsorption frame 2111 and a large-area adsorption substrate, and arranging multiple airflow channels 213 on the adsorption substrate, the airflow can flow across the entire surface of the adsorption substrate, resulting in a large contact area with the airflow and a good adsorption effect. In addition, the adsorption structure using the adsorption substrate assembled inside the first adsorption frame 2111 is simple.
[0104] In some embodiments, as shown in Figures 2 and 3, the adsorption substrate 211 may include a first adsorption frame 2111 and an adsorption member 2112 assembled within the first adsorption frame 2111. The adsorption substrate 211 has a substrate forming surface 214 located in the airflow path of the adsorption substrate. The substrate forming surface 214 may be a side surface of the adsorption substrate 211, and an adsorption coating 212 is coated on the side surface of the adsorption substrate 211.
[0105] In some other embodiments, the substrate surface 214 may also be the surface of the adsorption substrate 211 facing the airflow, and the adsorption coating 212 is coated on the surface of the adsorption substrate 211 facing the airflow.
[0106] In some embodiments, as shown in Figures 4 and 5, the adsorption substrate 211 may include a second adsorption frame 2113. An assembly space 2115 is formed inside the second adsorption frame 2113.
[0107] In some embodiments, as shown in Figures 4 and 5, the adsorption matrix may include adsorption sub-components 2114. Multiple adsorption sub-components 2114 may be provided. The adsorption sub-components 2114 may be assembled within the assembly space 2115 of the second adsorption frame 2113. Multiple adsorption sub-components 2114 may be parallel to each other and connected. Airflow channels 213 are formed between adjacent adsorption sub-components 2114.
[0108] In some embodiments, as shown in Figures 4 and 5, the adsorption sub-component 2114 can be an adsorption sub-fin. Multiple adsorption sub-fins can be provided, and these multiple adsorption sub-fins can be parallel to each other. Both ends of the adsorption sub-fins can be connected and fixed to the second adsorption frame 2113, which connects and supports the adsorption sub-fins. Airflow channels 213 formed between the adsorption sub-fins facilitate airflow, and an adsorption coating 212 is applied to the adsorption sub-fins.
[0109] In some embodiments, as shown in Figures 4 and 5, in order to connect the adsorption sub-components 2114, a temperature regulating component 221 can be inserted through multiple adsorption sub-components 2114 to connect the multiple adsorption sub-components 2114 together.
[0110] In some embodiments, as shown in Figures 4 and 5, the temperature control component 221 can be a heat exchange tube.
[0111] In some embodiments, as shown in FIG5, the temperature regulating component 221 may be coated with the adsorption coating 212. By also coating the temperature regulating component 221 with the adsorption coating 212, the area of the adsorption coating 212 can be increased, the contact area with the airflow can be increased, and the adsorption effect can be improved.
[0112] In some embodiments, as shown in Figures 6 and 7, the air purification module may include an auxiliary heating module. The auxiliary heating module may be mounted on the adsorption member 2112. The auxiliary heating module can be used in conjunction with the heat exchange medium introduced into the temperature control component 221 to increase the temperature of the adsorption coating 212.
[0113] For example, when it is necessary to heat up the adsorption coating 212 for desorption, if the refrigerant introduced into the temperature control component 221 alone cannot reach the desorption temperature, the auxiliary heating module can be turned on to heat up the adsorption coating 212 to ensure that the adsorption coating 212 can reach the desorption and regeneration temperature for desorption.
[0114] In some embodiments, as shown in FIG7, the auxiliary heating module may include multiple auxiliary heating elements 24. The multiple auxiliary heating elements 24 may be interspersed inside the adsorption substrate 211. When the auxiliary heating elements 24 are energized, the heat generated by the auxiliary heating elements 24 can be transferred to the adsorption substrate 211, and then transferred to the adsorption coating 212 through the adsorption substrate 211 to provide auxiliary heating for the adsorption coating 212.
[0115] In some embodiments, as shown in FIG7, the heat exchange channel 2211 may include a first heat exchange section 2212. Two first heat exchange sections 2212 may be provided. The two first heat exchange sections 2212 may be arranged opposite to each other. The first heat exchange section 2212 may be embedded inside the adsorption substrate 211 and connected to the adsorption substrate 211.
[0116] In some embodiments, as shown in FIG7, the first heat exchange section 2212 can be a first heat exchange wall. Two first heat exchange sections 2212 are arranged opposite to each other. A gap exists between the two first heat exchange sections 2212. They are respectively connected and fixed to the adsorption substrate 211 on their corresponding sides.
[0117] In some embodiments, the adsorption substrate 211 and the temperature control component 221 can be integrally formed, or they can be connected by welding or mortise and tenon structure to ensure effective heat transfer between them.
[0118] In some embodiments, as shown in FIG7, the heat exchange channel 2211 may include a second heat exchange section 2213. Two second heat exchange sections 2213 may be provided. The two second heat exchange sections 2213 may be respectively connected to the two ends of the two first heat exchange sections 2212. The second heat exchange sections 2213 may at least partially protrude from the adsorption substrate 211. An airflow guide section 2214 may be formed on the second heat exchange section 2213 to guide the airflow flowing through the adsorption substrate 211.
[0119] In some embodiments, as shown in FIG7, the second heat exchange portion 2213 may be a second heat exchange wall. The second heat exchange wall may be bent. The second heat exchange wall may include a first bent wall and a second bent wall. The airflow guide portion 2214 may be a first guide surface formed on the first bent wall and a second guide surface formed on the second bent wall. Wherein, the first guide surface and the second guide surface are inclined surfaces, and the inclination directions of the first guide surface and the second guide surface are opposite.
[0120] In some embodiments, as shown in FIG7, the first guide surface and the second guide surface can be arranged to face the airflow passing through the adsorption substrate. As the airflow passes, the first guide surface and the second guide surface can guide the airflow. The airflow guide portion 2214 significantly reduces the resistance of the device, thereby reducing pressure loss.
[0121] In some embodiments of this disclosure, as shown in Figures 6 and 7, the air purification module may include an ultraviolet (UV) sterilization component 25. The UV sterilization component 30 may be mounted on the adsorption substrate 211. The light emission direction of the UV sterilization component 30 is directed towards the adsorption coating 212. By ensuring that the light emission direction of the UV sterilization component 25 is directed towards the adsorption coating 212, it is guaranteed that the UV light emitted by the UV sterilization component 30 can irradiate the adsorption coating 212.
[0122] In some embodiments, as shown in FIG6, an ultraviolet sterilization component 25 may be disposed on the first adsorption frame 2111 on the windward side of the air purification module. A gap may exist between the ultraviolet sterilization component 25 and the adsorption member 2112.
[0123] In some embodiments, the ultraviolet sterilization component 25 may include a substrate and ultraviolet lamp beads. The ultraviolet lamp beads may be LED lamp beads. Multiple ultraviolet lamp beads may be provided, and the multiple ultraviolet lamp beads may be arranged alternately by LED lamp beads of different wavelengths. The wavelength range of the ultraviolet lamp beads may be in the range of 185 to 375 nm.
[0124] The ultraviolet (UV) sterilization component 25 directly irradiates the windward surface of the adsorption substrate 211 from the windward side, serving two main functions. Firstly, UV light has a bactericidal effect, preventing bacterial growth on the surfaces of the adsorption substrate 211 and adsorption coating 212 after prolonged use. This bacterial growth could then cover the micropores of the adsorption coating 212, affecting the adsorption efficiency of odors. Secondly, UV light can react with the photocatalyst on the surface of the adsorption coating 212 to undergo a photocatalytic oxidation reaction, thus enhancing the purification effect.
[0125] In some embodiments of this disclosure, as shown in FIG10, an air conditioner is provided, which may include a housing 100 and a return air section 110 and an air outlet section 120 arranged on the housing 100.
[0126] In some embodiments, as shown in FIG10, the air conditioner may include a heat exchange duct 130. The heat exchange duct 130 is disposed within the housing 100. The heat exchange duct 130 can be used to circulate gas, allowing the gas to exchange heat within the heat exchange duct 130.
[0127] In some embodiments, as shown in FIG10, the air conditioner may include an air supply device 300, which may be disposed in the heat exchange duct 130 and may be used to drive gas to flow in the heat exchange duct 130.
[0128] In some embodiments, as shown in FIG10, the air conditioner may include an air purification module, which may be installed in the return air section 110, the air outlet section 120, or the heat exchange duct 130. When in use, the air purification module may be positioned at the return air section 110 for adsorption purification, or it may be positioned at the air outlet section 120 or in the heat exchange duct 130 for adsorption purification.
[0129] In some embodiments, as shown in FIG10, the air purification module can be arranged at the return air section 110, and the air conditioner has an adsorption operation mode and a desorption operation mode.
[0130] In some embodiments, as shown in Figures 5, 8, and 10, when the air conditioner is in adsorption operation mode, airflow can be drawn from the return air section 110 into the heat exchange duct 130 through the air supply device 300. The airflow is adsorbed and purified by the air purification module at the return air section 110, and then the airflow can be delivered from the air outlet section 120. In this mode, the air supply device 300 rotates in a first direction, and the lower-temperature refrigerant introduced into the heat exchange channel 2211 of the air purification module exchanges heat with the adsorption coating 212 to reduce the temperature of the adsorption coating 212 and improve the adsorption effect of the adsorption coating 212.
[0131] In some embodiments, as shown in Figures 5, 9, and 10, when the air conditioner is in desorption operation mode, the air supply device 300 can rotate in a second direction. This second direction is opposite to the first direction. At this time, a higher-temperature refrigerant is introduced into the heat exchange channel 2211 to exchange heat with the adsorption coating 212, increasing the temperature of the adsorption coating 212. The increased temperature of the adsorption coating 212 leads to desorption and regeneration, and the reverse rotation of the air supply device 300 allows the exhaust gas from the desorption and regeneration process to be discharged outdoors.
[0132] Air purification modules can be used not only in air handling equipment such as air conditioners and air conditioning systems, but also in air handling equipment such as total heat exchangers.
[0133] Total heat exchangers are high-efficiency and energy-saving heat recovery devices. When indoor exhaust air and outdoor fresh air flow through the total heat exchanger core in a cross-flow manner, the two airflows exhibit heat and mass transfer phenomena as they pass through the airflow partition plate due to the temperature difference and vapor pressure difference on both sides of the airflow partition plate, thus causing the total heat exchange process.
[0134] In order to achieve the purification function, the total heat exchanger of related technologies will have a variety of built-in air purification modules to filter and purify the air, thereby obtaining clean air.
[0135] Air purification modules used in total heat exchangers primarily employ various filter structures, such as HEPA filters, activated carbon filters, and formaldehyde filters, for filtration, deodorization, or formaldehyde removal. These filter structures involve coating a substrate with a filter layer made of activated carbon or other formaldehyde-removing adsorbents. These filters have a limited lifespan; once saturated, they must be replaced. Most saturated filters are discarded, mainly because users lack dedicated desorption and regeneration equipment. Furthermore, the desorption and regeneration of the adsorption coating requires strict temperature control; improper control could lead to fire, resulting in high user costs. Additionally, the short saturation cycle necessitates frequent filter replacements, increasing workload and costs while reducing user experience.
[0136] To address the aforementioned problems, in some embodiments of this disclosure, as shown in FIG11, a total heat exchanger is provided, which may include a housing 100. A fresh air duct 1100 is formed within the housing 100. The fresh air duct 1100 is used to introduce outdoor fresh air into the room. A fresh air inlet 1101 and a fresh air outlet 1102 are respectively formed at both ends of the fresh air duct 1100. The fresh air duct 1100 constitutes a fresh air introduction channel, allowing airflow to introduce outdoor fresh air into the fresh air duct 1100 through the fresh air inlet 1101, and then exhaust it into the room through the fresh air outlet 112.
[0137] In some embodiments, as shown in Figures 11 and 12, the fresh air duct 1100 may include a fresh air inlet duct 1103 and a fresh air outlet duct 1104 arranged diagonally opposite to the fresh air inlet duct 1103. The fresh air inlet 1101 may be a fresh air inlet located at one end of the fresh air inlet duct 1103. The fresh air outlet 11021 may be a fresh air outlet located at the other end of the fresh air outlet duct 1104.
[0138] In some embodiments, as shown in FIG11, a fresh air inlet valve may be provided at the fresh air inlet 1101 to control the opening and closing of the fresh air inlet 1101. In some embodiments, as shown in FIG11, a fresh air outlet valve may be provided at the fresh air outlet 1102 to control the opening and closing of the fresh air outlet 1102.
[0139] In some embodiments, as shown in Figures 11 and 12, the total heat exchanger may include a fresh air fan 1200, which may be arranged within a fresh air duct 1100. The fresh air fan 1200 can drive the airflow within the fresh air duct 1100. The fresh air fan 1200 draws in outdoor air from the fresh air inlet 1101 and then sends the air out through the fresh air outlet 1102, thereby delivering fresh outdoor air to the room.
[0140] In some embodiments, as shown in FIG11, the total heat exchanger may include a stale air duct 1300, which is used to exhaust indoor stale air to the outside. A stale air inlet 1301 and a stale air outlet 1302 may be formed at both ends of the stale air duct 1300. The stale air duct 1300 constitutes a stale air exhaust channel, through which airflow can introduce indoor stale air into the stale air duct 1300 via the stale air inlet 1301, and then exhaust it to the outside via the stale air outlet 1302.
[0141] In some embodiments, as shown in FIG11, the waste air duct 1300 may include a waste air inlet duct 1303 and a waste air outlet duct 1304 arranged opposite to the waste air inlet duct 1303. The waste air inlet 1301 may be a fresh air inlet located at one end of the waste air inlet duct 1303. The waste air outlet 1302 may be a waste air outlet located at the other end of the waste air outlet duct 1304.
[0142] In some embodiments, as shown in FIG11, a waste air inlet valve may be provided at the waste air inlet 1301 to control the opening and closing of the waste air inlet 1301.
[0143] In some embodiments, as shown in FIG11, a fresh air outlet valve may be provided at the waste air outlet 1302 to control the opening and closing of the waste air outlet 1302.
[0144] In some embodiments, as shown in FIG11, the total heat exchanger may include an exhaust fan 1400, which may be arranged within the waste air duct 1300. The exhaust fan 1400 may be used to drive the airflow within the waste air duct 1300 to ensure that indoor waste air can enter through the waste air inlet 1301 and be discharged through the waste air outlet 1302.
[0145] In some embodiments, as shown in FIG11, the total heat exchanger may include a total heat exchange core 150. The total heat exchange core 150 may be arranged at the intersection of the fresh air duct 1100 and the waste air duct 1300, so that the airflow flowing through the fresh air duct 1100 and the airflow flowing through the waste air duct 1300 can both flow through the total heat exchange core 150.
[0146] In some embodiments, as shown in Figures 11 and 12, the total heat exchanger may include an air purification module 200, which is arranged within the fresh air duct 1100. The air purification module 200 may be located on the airflow path of the fresh air duct 1100, and can adsorb and purify the airflow passing through the fresh air duct 1100.
[0147] In some embodiments, as shown in Figures 13 and 14, the air purification module 200 may include an adsorption module 210, which can be used to purify the airflow flowing in the fresh air duct 1100.
[0148] In some embodiments, as shown in Figures 13 and 14, the air purification module 200 may include a temperature control module 220, which may be connected to the adsorption module 210 and may be used to adjust the temperature of the adsorption module 210. The temperature adjustment of the adsorption module 210 by the temperature control module 220 may include both heating and cooling adjustments.
[0149] For example, when the adsorption module 210 is performing adsorption operations, the temperature control module 220 can be used to cool down the adsorption module 210, thereby improving the adsorption performance, adsorption capacity and adsorption efficiency of the adsorption module 210.
[0150] For example, when the adsorption module 210 is saturated, the temperature control module 220 can be used to raise the temperature of the adsorption module 210. The increased temperature of the adsorption module 210 allows for high-temperature desorption and regeneration, enabling the adsorption module 210 to continue to be used. This shortens the replacement cycle of the entire adsorption module 210 and extends its service life. In this way, users do not need to frequently disassemble and replace the filter, reducing their workload and improving their user experience.
[0151] In some embodiments, as shown in Figures 13, 15, and 16, the adsorption module 210 may include an adsorption substrate 211, on which an adsorption coating 212 may be coated. The adsorption coating 212 can be used to purify the airflow flowing through the heat exchange duct.
[0152] In some embodiments, the adsorption coating 212 may be composed of porous adsorption materials such as activated carbon, molecular sieves, or graphene. The surface of the adsorption coating 212 has micropores, through which airflow passing through it can be adsorbed.
[0153] In some embodiments, as shown in Figures 13 and 15, the temperature control module 220 may include a temperature control component 221 and a refrigerant supply module 222 connected to the temperature control component 221. The temperature control component 221 may be mounted on the adsorption substrate 211. A heat exchange channel 2211 for introducing a medium may be formed inside the temperature control component 221. The heat exchange channel 2211 may be connected to the refrigerant supply module 222, which can supply refrigerant at different temperatures to the heat exchange channel 2211. By mounting the temperature control component 221 onto the adsorption substrate 211, heat exchange occurs between the refrigerant introduced inside the temperature control component 221 and the adsorption substrate 211 and the adsorption coating 212, thereby adjusting the temperature of the adsorption coating 212 and changing the temperature of the adsorbent material constituting the adsorption coating 212.
[0154] For example, when the temperature of the refrigerant flowing into the temperature regulating component 221 is low, the low-temperature refrigerant exchanges heat with the adsorption substrate 211 and the adsorption coating 212, which lowers the temperature of the adsorption substrate 211 and the adsorption coating 212 above it, thereby lowering the temperature of the adsorbed substance in the adsorption coating 212, improving the adsorption performance, making the adsorption more complete, and improving the adsorption efficiency and adsorption capacity.
[0155] For example, when the refrigerant flowing into the temperature control component is a high-temperature refrigerant, the high-temperature refrigerant will exchange heat with the adsorption substrate 211 and the adsorption coating 212, causing the temperature of the adsorption coating 212 to rise. Once the adsorption coating 212 rises to a certain temperature, it can achieve desorption and regeneration.
[0156] In some embodiments, as shown in FIG16, an airflow channel 213 penetrating the adsorption substrate 211 may be formed on the adsorption substrate 211. An adsorption coating 212 may be coated on the inner wall of the airflow channel 213.
[0157] In some embodiments, as shown in FIG15, the adsorption substrate 211 may include a first adsorption frame 2111 and an adsorption plate 2112 assembled within the first adsorption frame 2111. An airflow channel 213 penetrating the adsorption plate 2112 may be provided on the adsorption plate 2112. An adsorption coating 212 may be applied to the inner wall of the airflow channel 213, and the airflow is adsorbed and purified by the adsorption coating 212 when it flows through the airflow channel 213.
[0158] In some embodiments, as shown in FIG15, the adsorption substrate 211 may include a first adsorption frame 2111 and an adsorption plate 2112 assembled within the first adsorption frame 2111. The adsorption plate 2112 may have a substrate forming surface 214 located in the airflow path of the adsorption substrate 211. An adsorption coating 212 may be applied to the substrate forming surface 214.
[0159] In some embodiments, as shown in FIG17, the adsorption substrate 211 may include a second adsorption frame 2113.
[0160] In some embodiments, as shown in Figures 17 and 18, the adsorption substrate 211 may include adsorption sub-components 2114. Multiple adsorption sub-components 2114 may be provided. Multiple adsorption sub-components 2114 may be assembled on the second adsorption frame 2113. Multiple adsorption sub-components 2114 may be parallel to each other and connected. Airflow channels 213 may be formed between adjacent adsorption sub-components 2114. An adsorption coating 212 is applied to the outer wall of the adsorption sub-components 2114 constituting the airflow channels 213. When airflow passes through the airflow channels 213 between the multiple adsorption sub-components 2114, it passes over the outer surfaces of the multiple adsorption sub-components 2114 and is adsorbed by the adsorption coating 212.
[0161] In some embodiments, as shown in FIG18, an adsorption coating 212 may be applied to the temperature regulating component 221, which can increase the area of the adsorption coating 212, increase the contact area with the airflow, and improve the adsorption effect.
[0162] In some embodiments, as shown in Figures 17 and 18, the temperature control component 221 may be embedded inside the adsorption substrate 211. A bent heat exchange channel 2211 may be formed inside the temperature control component 221.
[0163] In some embodiments, as shown in Figures 17 and 18, the adsorption substrate 211 may include a second adsorption frame 2113 and adsorption sub-components 2114. A plurality of second adsorption frames 2113 are assembled on the second adsorption frames 2113. A plurality of adsorption sub-components 2114 are parallel to each other and connected in series via a temperature control component 221.
[0164] In some embodiments, as shown in Figures 15 and 16, the adsorption substrate 211 may include a first adsorption frame 2111 and the adsorption substrate 211 assembled within the first adsorption frame 2111. The temperature control component 221 may be disposed vertically through the adsorption substrate 211.
[0165] In some embodiments, the temperature control component 221 may also be attached to the outer surface of the adsorption substrate 211, and it may also exchange heat with the adsorption coating 212 by exchanging heat with the adsorption substrate 211.
[0166] In some embodiments, to improve the heat exchange effect and achieve rapid temperature regulation of the adsorption coating 212, the material of the adsorption substrate 211 can be selected as a thermally conductive material.
[0167] In some embodiments, the adsorption substrate 211 can be a metallic material such as copper or aluminum, or a ceramic material such as alumina or silicon nitride.
[0168] In some embodiments, the total heat exchanger may have a total heat exchange mode and an internal circulation mode.
[0169] In some embodiments, as shown in FIG11, when the total heat exchanger is in total heat exchange mode, outdoor fresh air can be drawn into the fresh air duct 1100 from the fresh air inlet 1101 by the fresh air fan 1200, purified by the air purification module 200 located in the fresh air duct 1100, enter the total heat exchange core 150, and then be discharged into the room from the fresh air outlet 1102. Indoor stale air can be drawn into the stale air inlet 1301 by the stale air fan 1400, enter the stale air inlet duct 1303, and be discharged from the stale air outlet 1302 after passing through the total heat exchange core 150. At this time, the fresh air flowing through the fresh air duct 1100 and the air flowing through the stale air duct 1300 can exchange heat in the total heat exchange core 150, so that the air discharged from the fresh air outlet is the heat-exchanged air, transferring the heat of the indoor air to the fresh air and sending it back into the room, thereby saving energy and reducing energy consumption.
[0170] In some embodiments, as shown in FIG11, during operation in the total heat exchange mode, the temperature of the heat exchange medium flowing into the temperature control module 220 can be controlled to exchange heat with the adsorption coating 212 on the adsorption substrate 211 to regulate the temperature of the adsorption coating 212, thereby ensuring the air purification effect.
[0171] In some embodiments, as shown in FIG11, a primary filter can be installed in the waste air inlet channel 1303, which can filter out large particulate matter and pollutants such as hair in the air.
[0172] In some embodiments, as shown in FIG11, a high-efficiency filter may be installed in the fresh air intake duct 1103. The high-efficiency filter can filter out particulate matter and pollutants such as hair in the air. The high-efficiency filter may be located on the front side of the air purification module 200.
[0173] In some embodiments, as shown in FIG12, when the total heat exchanger is in internal circulation mode: the fresh air inlet 1101 and the waste air outlet 1302 are closed, the fresh air outlet 1102 and the waste air inlet 1301 are open, the exhaust fan 1400 is closed, the fresh air fan 1200 is open, and the fresh air inlet duct 1103 and the waste air outlet duct 1304 are connected. At this time, the indoor airflow enters through the waste air inlet 1301, flows through the waste air duct 1300 in sequence, enters the fresh air inlet duct 1103 of the fresh air duct 1100, flows through the purification adsorption module 210, and is discharged from the fresh air outlet 112.
[0174] In some embodiments, as shown in FIG12, when running in internal circulation mode, the temperature control module 220 can also adjust the temperature of the adsorption coating 212 by exchanging heat between its internal heat exchange medium and the adsorption coating 212 on the adsorption substrate 211, so as to ensure the adsorption performance of the adsorption coating 212.
[0175] In some embodiments, as shown in FIG13, the total heat exchanger may include a desorption control valve module. The desorption control valve module may be disposed inside the housing 100. The desorption control valve module can change the flow path of the airflow in the fresh air duct 1100 and the stale air duct 1300 by switching it on and off, so that the airflow in the desorption mode is discharged from the stale air outlet 1302.
[0176] When the adsorption module 210 reaches saturation after a period of use and needs desorption, the temperature control module 220 can be used to heat the adsorption module 210 to achieve desorption and regeneration. During desorption and regeneration, the adsorption module 210 will re-evaporate the odor substances adsorbed inside. To prevent the volatile odor substances from entering the room, the desorption control valve module is used to open and close accordingly, changing the airflow path so that the odor substances from the evaporation point can be discharged through the waste air outlet 1302.
[0177] In some embodiments, as shown in FIG11, the air purification module 200 is arranged in the fresh air inlet channel 1103 and close to the fresh air inlet 1101 to ensure that the airflow entering the fresh air duct 1100 first flows through the air purification module 200 for purification.
[0178] In some embodiments, as shown in FIG13, the desorption control valve module may include a first control valve 16. The first control valve 16 may be used to isolate or connect the fresh air inlet channel 1103 and the waste air outlet channel 1304. The first control valve 16 may be located further away from the fresh air inlet 1101 than the air purification module 200.
[0179] When the first control valve 16 is opened, as shown in Figure 13, the fresh air inlet channel 1103 and the waste air outlet channel 1304 are interconnected. At this time, the fresh air outlet 1102 and the waste air inlet 1301 are closed, and in conjunction with the opening of the exhaust fan 1400, the desorbed odors can be discharged. For example, when the exhaust fan 1400 is running, it drives the airflow from the fresh air inlet channel 1103 to the waste air outlet channel 1304, and drives the odor substances desorbed and volatilized by the air purification module 200 to flow, so that they are discharged outward through the waste air outlet 1302.
[0180] When the first control valve 16 is closed, as shown in Figure 14, the fresh air inlet channel 1103 and the waste air outlet channel 1304 can be separated.
[0181] In some embodiments, as shown in FIG13, the desorption control valve module may include a second control valve 17. The second control valve 17 may be used to isolate or connect the fresh air outlet duct 1104 and the waste air inlet duct 1303. The second control valve 17 may be located further away from the fresh air inlet 1101 than the first control valve 16.
[0182] When the second control valve 17 is opened, as shown in Figure 14, the first control valve 16 is closed. At this time, the fresh air outlet 1102 and the waste air inlet 1301 are closed, and the fresh air inlet channel 1103 and the waste air outlet channel 1304 are interconnected. In conjunction with the opening of the exhaust fan 1400, the desorbed odors can also be discharged. For example, when the exhaust fan 1400 rotates, it drives the airflow from the fresh air inlet channel 1103 through the total heat exchange core 150 into the fresh air outlet channel 1104 and the waste air inlet channel 1303, and then flows through the waste air outlet channel 1304, so as to carry the odor substances desorbed and volatilized in the air purification module 200 to the waste air outlet 1302 for discharge.
[0183] When the second control valve 17 is closed, as shown in Figure 13, the fresh air outlet channel 1104 and the waste air inlet channel 1303 can be separated.
[0184] In some embodiments, as shown in Figures 13 and 14, the airflow direction can be changed by switching the opening and closing of the first control valve 16 or the second control valve 17, so as to switch different desorption methods and ensure that the desorbed odor gas is discharged.
[0185] In some embodiments, as shown in FIG12, the total heat exchanger may include a third control valve 18. The third control valve 18 may be arranged in the fresh air inlet channel 1103 or the waste air outlet channel 1304. The third control valve 18 may be used to separate or connect the fresh air inlet channel 1103 and the waste air outlet channel 1304. The third control valve 18 may be closer to the fresh air inlet 1101 than the air purification module 200. The third control valve 18 may be configured to open when the internal circulation mode is started. When the third control valve 18 is open, the fresh air inlet channel 1103 and the waste air outlet channel 1304 are connected, and the airflow can enter from the waste air inlet 1301, flow through the waste air inlet channel 1303, the total heat exchange core 150, and the waste air outlet channel 1304, then enter the fresh air inlet channel 1103, pass through the total heat exchange core 150, and exit from the fresh air outlet 1102 of the fresh air outlet channel 1104.
[0186] In some embodiments, as shown in Figures 13 and 14, the total heat exchanger may include a heat storage component 19. The heat storage component 19 can be used for energy storage and can be mounted on the total heat exchange core 150. During thermal desorption of the air purification module 200, the generated heat is wasted; to achieve heat recovery and utilization, a heat storage component 19 is provided on the total heat exchange core 150.
[0187] In some embodiments, the heat storage component 19 may be a heat storage ceramic.
[0188] In some embodiments, as shown in FIG13, when the first control valve 16 is opened, since the airflow does not flow through the total heat exchange core 150, all the heat generated by desorption is discharged to the outside, and therefore, no heat is stored through the heat storage component 19. Otherwise, after desorption is completed, when the total heat exchange mode or the internal circulation module is turned on, the heat of the heat storage component 19 will be blown back into the room, causing discomfort to people.
[0189] In some embodiments, as shown in FIG14, when the second control valve 17 is opened, the airflow will flow through the total heat exchange core 150, and at this time, the heat can be recovered and utilized through the heat storage component 19.
[0190] In some embodiments, as shown in FIG13, the heat storage component 19 may be arranged on the portion of the total heat exchange core 150 located within the fresh air inlet channel 1103, and the heat storage component 19 may be further away from the fresh air inlet 1101 than the air purification module 200. By making the heat storage component 19 further away from the fresh air inlet 1101 than the air purification module 200, it can be ensured that the airflow flows through the air purification module 200 first and then through the heat storage component 19, so as to ensure that the heat storage component 19 can recover desorption heat.
[0191] In addition, since the airflow enters the fresh air inlet channel 1103 after passing through the air purification module 200, the heat storage component 19 is arranged on the part of the total heat exchange core 150 located in the fresh air inlet channel 1103. This ensures that the airflow can directly enter the heat storage component 19 for collection after flowing out of the purification adsorption module 210, without causing heat loss or waste, and the heat recovery effect is good.
[0192] In some other embodiments, as shown in FIG14, the heat storage component 19 may also be arranged on the portion of the total heat exchange core 150 located within the fresh air outlet channel 1104; or, it may also be arranged on the portion of the total heat exchange core 150 located within the waste air inlet channel 1303; or, it may also be arranged on the portion of the total heat exchange core 150 located within the waste air outlet channel 1304. As long as the heat storage component 19 is located in the airflow path during desorption, heat can be recovered.
[0193] In some embodiments, as shown in Figures 13 and 14, the adsorption module 210 may have two different desorption modes, namely a first desorption mode and a second desorption mode. During desorption, different desorption modes can be selected according to the current outdoor ambient temperature.
[0194] In some embodiments, as shown in Figures 13 and 19, the total heat exchanger may include a control element. The control element may be configured to:
[0195] Upon receiving a heat desorption command, the system detects the fresh air temperature, which corresponds to the outdoor ambient temperature. If the detected fresh air temperature is higher than the set fresh air temperature, it indicates that the outdoor temperature is higher than the set fresh air temperature, meaning the usage scenario is outside of winter.
[0196] At this point, the heat generated by thermal desorption is not easily recovered, and in order to reduce wind resistance, the airflow operates along the shortest path, controlling the system to enter the first desorption mode:
[0197] Control the fresh air fan 1200 to be closed, the sewage fan 1400 to be opened, the fresh air inlet 1101 and the sewage outlet 1302 to be opened, and the fresh air outlet 1102 and the sewage inlet 1301 to be closed.
[0198] The second control valve 17 and the third control valve 18 are closed, and the first control valve 16 is opened, so as to form a first desorption air duct between the fresh air inlet duct 1103 and the waste air outlet duct 1304.
[0199] Fresh air enters through the fresh air inlet 1101, passes through a high-efficiency filter to remove particles and hair from the air, and then enters the air purification module 200. At this time, a high-temperature refrigerant flows inside the air purification module 200, heating it and causing the odor substances previously adsorbed on the adsorption device to evaporate. The evaporated gas then passes through the first control valve 16 and directly enters the waste air outlet 1304, and is then discharged outdoors through the waste air outlet 1302 under the action of the exhaust fan 1400.
[0200] At this time, the outdoor ambient temperature is high and the indoor ambient temperature is low. Since the odor adsorption device needs to be heated before it can be desorbed, the heat after heating does not need to be recovered and can be directly discharged. The desorbed exhaust gas does not pass through the heat storage component 19.
[0201] In some embodiments, as shown in Figures 14 and 19, the control element can be configured as follows:
[0202] When a thermal desorption command is received, the fresh air temperature is detected. If the detected fresh air temperature is lower than the set fresh air temperature, it indicates that the outdoor temperature is lower than the set fresh air temperature, which means that the outside temperature is low and it is winter. In order to save energy, the heat generated during the thermal desorption process needs to be recovered. At this time, the second desorption mode is activated.
[0203] Control the fresh air fan 1200 to be closed, the sewage fan 1400 to be opened, the fresh air inlet 1101 and the sewage outlet 1302 to be opened, and the fresh air outlet and the sewage inlet 1301 to be closed.
[0204] The third control valve 18 is controlled to close, the first control valve 16 is controlled to open, and the second control valve 17 is controlled to form a second desorption duct between the fresh air inlet duct 1103 and the waste air outlet duct 1304.
[0205] Fresh air enters through the fresh air inlet 1101, passes through a high-efficiency mesh to remove large particles and hair, and then passes through the odor air purification module 200. At this time, a high-temperature refrigerant flows through the air purification module 200 to heat the module and volatilize the foreign matter originally adsorbed on the adsorption device. The volatilized gas passes through the heat storage ceramic to recover the heat, and then enters the total heat exchange core 150, then enters the fresh air outlet duct 1104, and then enters the stale air inlet duct 1303 through the second control valve 17. It then passes through the total heat exchange core 150 again and enters the stale air outlet duct 1304. Under the action of the exhaust fan 1400, it is discharged outdoors through the stale air outlet 132.
[0206] At this time, the outdoor ambient temperature is low, while the indoor ambient temperature is high. Since the odor adsorption device needs to be heated before desorption, the heat generated is recovered through the heat storage ceramic. After desorption is completed, when the total heat exchange mode or the internal circulation module is turned on, the heat from the heat storage ceramic will be blown back into the room for heat recovery and reuse.
[0207] In some embodiments, an auxiliary heating module is provided in the fresh air inlet duct 1103. The auxiliary heating module can be mounted on the adsorption module 210.
[0208] When the temperature supplied by the refrigerant supply module 222 to the temperature control module 220 cannot reach the temperature required for thermal desorption, the auxiliary heating module can be turned on to provide auxiliary heating to ensure that the temperature requirement for thermal desorption can be met.
[0209] In some embodiments, as shown in FIG11, the control element may be configured to: detect the operating mode of the total heat exchanger, and when the total heat exchanger is detected to be in the total heat exchange mode, not to adjust the temperature of the air purification module 200.
[0210] When in full heat exchange mode, the air in the fresh air duct mainly comes from the outside fresh air. The pollutants in the fresh air are mainly particulate matter and contain almost no pollutants such as bacteria, viruses, formaldehyde, TVOC, and odors. Therefore, in full heat exchange mode, the temperature of the air purification module 200 will not be adjusted, and room temperature purification can be performed directly.
[0211] In some embodiments, a first odor detection element may be provided in the total heat exchanger. The first odor detection element may be arranged on the rear side of the air purification module 200 to detect the odor concentration of the airflow flowing through the air purification module 200.
[0212] In some embodiments, the total heat exchanger may include a temperature and humidity sensing element. The temperature and humidity sensing element may be arranged in front of the air purification module 200, and may be used to detect the temperature and humidity before the air flows through the air purification module 200.
[0213] In some embodiments, the total heat exchanger may include a purification module temperature detection element, which can be used to detect the temperature of the air purification module 200.
[0214] In some embodiments, the control element may be configured to communicate with a temperature and humidity detection element to obtain temperature and humidity signals before the air flows through the air purification module 200, and to obtain the dew point temperature of water vapor in the air based on the temperature and humidity signals. It should be noted that the dew point temperature of water vapor in the air obtained through temperature and humidity calculations is directly obtainable and calculated by those skilled in the art, and will not be elaborated upon here.
[0215] In some embodiments, the control element may be configured to communicate with the first odor detection element to obtain a first odor concentration signal.
[0216] In some embodiments, the control element may be configured to communicate with the purification module temperature detection element to obtain the temperature signal of the air purification module 200.
[0217] In some embodiments, as shown in FIGS. 12 and 20, the control element may be configured to detect the operating mode of the total heat exchanger. When it is detected that the total heat exchanger is in the internal circulation mode, according to the dew point temperature of water vapor in the air, the first odor concentration signal, and the temperature signal of the air purification module 200, the temperature control module 220 is controlled to act to adjust the temperature of the adsorption module 210.
[0218] After the total heat exchanger is started and operates, each sensor starts to detect the temperature and humidity, the first odor concentration, and the temperature of the air purification module 200, and transmits the detected signals to the control element that communicates with it in real time.
[0219] Let: the first odor concentration be N, the first preset concentration be N1, the second preset concentration be N2, the temperature in front of the air purification module 200 be T, the humidity be H, the temperature of the air purification module 200 be t, the first odor concentration be N, the dew point temperature of water vapor in the air be T dew, and the critical dew point temperature be T dew + 1°C.
[0220] In some embodiments, at the initial operating state of the total heat exchanger, the air purification module 200 has good adsorption performance and a low odor concentration, meeting the use requirements, and it may not be necessary to adjust the temperature of the adsorption module 210.
[0221] In some embodiments, as shown in FIG. 20, the control element may be configured to, when it is detected that the first odor concentration is less than the first preset concentration, control the temperature control module 220 not to act, that is, when N < N1, the total heat exchanger operates normally.
[0222] With the accumulation of the operating time, pollutants continuously accumulate on the adsorption coating 212, causing the value of the first odor concentration to gradually increase.
[0223] In some embodiments, as shown in FIG. 20, when the control element detects that the first odor concentration is greater than the first preset concentration and less than the second preset concentration, the following control is cyclically executed until the temperature of the adsorption module 210 is reduced to the critical dew point temperature or the first temperature.
[0224] The control for the cyclic execution of the control element is as follows: control the temperature adjustment module 220 to lower the temperature of the adsorption module 210; obtain the dew point temperature of the water vapor in the air according to the values of the temperature and humidity detection element, compare the dew point temperature of the water vapor in the air with the temperature of the air purification module 200, and when the temperature of the air purification module 200 is greater than the dew point temperature of the water vapor in the air, control the air purification module 200 to operate for a preset time.
[0225] Among them, the critical dew point temperature is greater than the dew point temperature of the water vapor in the air; the first temperature corresponds to the temperature that remains unchanged after multiple cooling controls are executed. The temperature of the adsorption module 210 is the temperature of the air purification module 200.
[0226] When it is detected that N1 < N < N2, it means that the odor concentration exceeds the first critical value and is less than the second critical value. At this time, the purification ability of the air purification module 200 begins to weaken. The control element then needs to control the temperature adjustment module 220 to cool down the adsorption module 210.
[0227] For the first cooling, the temperature of the adsorption module 210 is first reduced from the normal temperature t to t1.
[0228] At the same time, the control element automatically calculates the dew point temperature Tdew of water in the current environment according to the temperature T and humidity H, and compares it with the temperature t1. If the temperature t1 of the adsorption module 210 is higher than the dew point temperature Tdew + 1°C, maintain this state and continue to operate for 10 - 20 min.
[0229] After the preset time, the first odor concentration N at the rear end of the air purification module 200 is detected again. If the first odor concentration is still within the range of N1 - N2, the control element continues to adjust the temperature of the adsorption module 210 to t2, where t2 < t1, and calculates the dew point temperature Tdew of the water vapor in the air again for comparison and judgment, and operates for the preset time of 10 - 20 min.
[0230] If the dew point temperature is not reached, continue to cool down the adsorption module 210 until it is reduced to t3, t3 < t2, and after operating for the preset time, compare it with the dew point temperature Tdew of the water vapor in the air again for judgment, and continuously cycle until the temperature of the adsorption module 210 is reduced to the critical dew point temperature and then no longer continues to decrease.
[0231] In some embodiments, t1, t2, and t3 change in a certain gradient. By having t1, t2, and t3 change in a certain gradient, it is possible to prevent the temperature of the air purification module 200 from being lower than the dew point temperature of the water in the air in the current state, and generating condensed water on the surface of the air purification module 200. If water vapor condenses on the air purification module 200, it will occupy the microporous structure of the adsorption material, thereby greatly reducing the adsorption performance of the adsorption material and further reducing the purification effect of the air purification module 200.
[0232] If, after detecting that the first odor concentration continues to decrease in the adsorption module 210 and has dropped to the first temperature, it is still within the range of N1 < N < N2, it indicates that the environmental dew point temperature is relatively low at this time and further cooling is not possible. The control element directly controls the adsorption module 210 to operate at the lowest achievable first temperature until the first odor concentration in the adsorption module 210 is N > N2, and then automatically enters the N > N2 control mode.
[0233] That is: when detecting that the first odor concentration signal is greater than the second preset concentration, the control element controls the temperature of the air purification module 200 to decrease to the critical dew point temperature or the first temperature.
[0234] In some embodiments, if the control element cannot reduce the temperature of the adsorption module 210 to the critical dew point temperature by controlling the temperature adjustment module 220, it indicates that the environmental dew point temperature is relatively low at this time. The control element can directly control the air purification module 200 to operate at the lowest achievable temperature, i.e., the first temperature.
[0235] In some embodiments, the control element is configured to: when executing the desorption instruction, detect the temperature of the air purification module 200, and control the opening and closing of the auxiliary heating module according to the detected temperature of the purification module and the preset temperature.
[0236] In some embodiments, the auxiliary heating module is mainly used to cooperate with the temperature adjustment component 221 to jointly increase the temperature of the air purification module 200. If the temperature of the air purification module 200 cannot reach the desorption temperature solely by relying on the refrigerant, the auxiliary heating module can be turned on for assistance.
[0237] In some embodiments, the auxiliary heating module can be a heating wire or a heating tube. When arranging the auxiliary heating module, it can be embedded inside the adsorption matrix 211.
[0238] In some embodiments, the control element can be configured to: when detecting that the temperature of the air purification module 200 is less than the first preset temperature, control the auxiliary heating module to turn on; when detecting that the temperature of the air purification module 200 is greater than the first preset temperature, control the auxiliary heating module to turn off. During the process of the temperature adjustment component 221 increasing the temperature of the air purification module 200 through the refrigerant, the temperature of the purification module can be monitored simultaneously by the purification module temperature detection element. When the required first preset temperature cannot be reached solely by relying on the refrigerant heating, control the auxiliary heating module to turn on for auxiliary temperature increase.
[0239] In some embodiments, the control element can be configured to: when executing the desorption instruction, obtain the first odor concentration value of the first odor detection element. When detecting that the concentration of the first odor detection element is less than the preset odor concentration, control the desorption to end. When detecting that the first odor concentration decreases to the preset odor concentration, it indicates that the odor substances have been completely desorbed, and the desorption process ends. The system control resumes to the operating state before the desorption mode.
[0240] In some embodiments, a quality sensor for controlling air quality may be installed in the fresh air outlet duct 1104. The quality sensor can monitor the air quality discharged from the fresh air outlet 1102 in real time. This sensor is not a single TVOC or formaldehyde sensor, but a sensor module that uses multiple sensors in combination, and can simultaneously monitor common pollutants such as PM2.5, formaldehyde, and TVOC.
[0241] In some embodiments, an air conditioning system is provided, which may include an outdoor unit. The outdoor unit contains a compressor and a condenser.
[0242] In some embodiments, the air conditioning system may include multiple indoor units. The multiple indoor units are connected in parallel, and each indoor unit 520 is equipped with an evaporator.
[0243] In some embodiments, the air conditioning system may include a total heat exchanger. The total heat exchanger is arranged in parallel with multiple indoor units, and the total heat exchanger includes a temperature control module 220. Multiple evaporators are arranged in parallel with the temperature control module 220. One end of the temperature control module 220 is connected to the condenser via a refrigerant line, and the other end of the temperature control module 220 is connected to the compressor.
[0244] In some embodiments, when the air purification module 200 is connected, it can be connected to the refrigerant pipeline of the entire air conditioning system through the temperature control module 220. The refrigerant distributed in the air conditioning system is used as the refrigerant supply module 222 of the temperature control module 220, so as to at least achieve the function of cooling the adsorption module 210 during cooling and thermally desorbing the adsorption module 210 during heating.
[0245] To achieve air purification, air conditioners using related technologies incorporate various air purification modules to filter and purify the air, thereby obtaining clean air.
[0246] Air purification modules used in air conditioners primarily employ various filter structures, such as HEPA filters, activated carbon filters, and formaldehyde filters, for filtration, deodorization, or formaldehyde removal. These filter structures involve coating a filter substrate with an adsorption material such as activated carbon or formaldehyde-removing agents. These filters have a limited lifespan; once saturated, they must be replaced. Most saturated filters are discarded, mainly because users lack dedicated desorption and regeneration equipment, and the desorption and regeneration of the adsorption coating requires strict temperature control—improper control could lead to fire—resulting in high user costs. Furthermore, the short saturation cycle of these filters necessitates frequent replacements, increasing workload and costs while reducing user experience.
[0247] To address the aforementioned problems, as shown in Figure 21, in some embodiments of this disclosure, an air conditioner is proposed, which may include a housing 100. The housing 100 may constitute the outer casing of the indoor unit of the air conditioner. A heat exchange air duct 130 is formed inside the housing 100.
[0248] In some embodiments, as shown in Figures 21 and 22, a return air section 110 may be formed on the housing 100. The return air section 110 may be an air inlet formed on the housing 100 so that external airflow can enter the interior of the housing 100.
[0249] In some embodiments, as shown in Figures 21 and 22, an air outlet 120 may be formed on the housing 100. The air outlet 120 may be an air vent formed on the housing 100, and the air outlet 120 may be used to discharge the heat-exchanged airflow.
[0250] In some embodiments, as shown in Figures 21 and 22, the air conditioner may include a heat exchange duct 130. The heat exchange duct 130 may be formed between the return air section 110 and the air outlet section 120, and can be used to circulate airflow. Airflow enters from the return air section 110, flows through the heat exchange duct 130, and exits from the air outlet section 120. The airflow entering the heat exchange duct 130 undergoes heat exchange within it.
[0251] In some embodiments, as shown in Figures 21 and 23, the air conditioner may include an evaporator 404. The evaporator 404 may be arranged within a heat exchange duct 130. The evaporator 404 can be used to exchange heat with the airflow flowing through the heat exchange duct 130. Through heat exchange between the evaporator 404 and the airflow within the heat exchange duct 130, the airflow can be heated or cooled, thereby ensuring that the airflow blown out from the air outlet 120 is heated or cooled, thus achieving the cooling or heating effect of the air conditioner.
[0252] In some embodiments, as shown in Figures 21 and 22, the air conditioner may include an air supply device 300. The air supply device 300 may be disposed within the heat exchange duct 130. The air supply device 300 can drive airflow to circulate within the heat exchange duct 130 and control the flow rate of the airflow within the heat exchange duct 130. The air supply device 300 draws airflow from the return air section 110 into the heat exchange duct 130 to exchange heat with the evaporator 404, and then delivers the airflow from the air outlet section 120. The air supply device 300 provides the power for the airflow circulation.
[0253] In some embodiments, as shown in Figures 24 and 25, the air conditioner may include a refrigeration cycle loop 400. The refrigeration cycle loop 400 may be formed by connecting a compressor 401, a main expansion valve 403, a condenser 402, and an evaporator 404 via refrigerant piping. The refrigeration cycle of the air conditioner is executed by using the compressor 401, condenser 402, main expansion valve 403, and evaporator 404. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.
[0254] In some embodiments, as shown in FIG24, a low-temperature, low-pressure refrigerant enters a compressor 401, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into a condenser 402. The condenser 402 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
[0255] In some embodiments, as shown in FIG24, the main expansion valve 403 expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser 402 into a low-pressure liquid refrigerant. The evaporator 404 evaporates the refrigerant expanded in the main expansion valve 403 and returns the low-temperature, low-pressure refrigerant gas to the compressor 401. The evaporator 404 achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material to be cooled. Throughout the cycle, the air conditioner can regulate the temperature of the indoor space.
[0256] In some embodiments, the outdoor unit of the air conditioner refers to the portion of the refrigeration cycle that includes the compressor 401 and the outdoor heat exchanger. The indoor unit of the air conditioner includes an indoor heat exchanger. An expansion valve may be provided in either the indoor or outdoor unit.
[0257] In some embodiments, the indoor heat exchanger and the outdoor heat exchanger serve as either a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger serves as an evaporator, the air conditioner functions as a cooler in cooling mode.
[0258] In some embodiments, as shown in FIG21, the air conditioner may include an air purification module 200. The air purification module 200 may be arranged at the return air section 110, and the air purification module 200 may be used to purify the air exhausted into the room.
[0259] In some other embodiments, the air purification module 200 may also be arranged at the air outlet 120, and the air purification module 200 may also purify the airflow when the airflow is discharged into the room.
[0260] In some other embodiments, the air purification module 200 can also be arranged inside the heat exchange duct 130. The air purification module 200 can also purify the airflow passing through the heat exchange duct 130, thus ensuring that the air entering the room is purified clean air.
[0261] In some embodiments, as shown in Figures 26 and 27, the air purification module 200 may include an adsorption substrate 211. An adsorption coating 212 is coated on the adsorption substrate 211. The adsorption coating 212 can be used to purify the airflow flowing within the heat exchange duct 130.
[0262] In some embodiments, the adsorption coating 212 may be composed of an adsorbent substance with adsorption properties. The adsorption substrate 211 serves as a carrier for the adsorption coating 212. The adsorption coating 212 achieves its corresponding adsorption function by being applied onto the adsorption substrate 211.
[0263] In some embodiments, the adsorption coating 212 may be an adsorption coating 212 composed of porous adsorption materials such as activated carbon, molecular sieves, or graphene. The surface of the adsorption coating 212 has micropores, through which the airflow passing through it can be adsorbed.
[0264] In some embodiments, as shown in Figures 28 and 29, the air purification module 200 may include a temperature regulating component 221. The temperature regulating component 221 may be mounted on the adsorption substrate 211. A heat exchange channel 2211 for introducing refrigerant may be formed inside the temperature regulating component 221. The temperature regulating component 221 may be connected to a refrigeration cycle loop 400, and the temperature regulating component 221 can exchange heat between the refrigerant diverted to its interior through the refrigeration cycle loop 400 and the adsorption coating 212, thereby regulating the temperature of the adsorption coating 212.
[0265] In some embodiments, as shown in Figures 24, 28 and 29, the temperature regulating component 221 can be connected to the refrigeration cycle loop 400, enabling it to divert a portion of the refrigerant in the refrigeration cycle loop 400. The refrigerant flowing in the refrigeration cycle loop 400 flows into the heat exchange channel 2211 inside the loop, where it exchanges heat with the adsorption coating 212 on the adsorption substrate 211, thereby regulating the temperature of the adsorbent in the adsorption coating 212.
[0266] In some embodiments, as shown in Figures 27 and 29, the temperature-regulating component 221 can be connected to the adsorption substrate 211. An adsorption coating 212 can be applied to the adsorption substrate 211 so that the heat exchange between the temperature-regulating component 221 and the adsorption coating 212 can be achieved through direct contact. Alternatively, the temperature-regulating component 221 can directly contact the thermally conductive adsorption substrate 211 for heat exchange, and then indirectly exchange heat with the adsorption coating 212, ultimately achieving the temperature regulation effect on the adsorption coating 212.
[0267] In some embodiments, in order to improve the heat exchange effect and achieve rapid temperature regulation of the adsorption coating 212, the material of the adsorption substrate 211 is selected as a thermally conductive material.
[0268] In some embodiments, the adsorption substrate 211 is a metallic material such as copper or aluminum, or a ceramic material such as alumina or silicon nitride.
[0269] In some embodiments, as shown in Figures 27 and 29, temperature regulation of the adsorption coating 212 includes both heating and cooling of the adsorption coating 212.
[0270] For example, when the temperature of the refrigerant flowing into the temperature regulating component 221 is low, the low-temperature refrigerant exchanges heat with the adsorption substrate 211 and the adsorption coating 212, which lowers the temperature of the adsorption substrate 211 and the adsorption coating 212 above it, thereby lowering the temperature of the adsorbed substance in the adsorption coating 212, improving the adsorption performance, making the adsorption more complete, and improving the adsorption efficiency and adsorption capacity.
[0271] For example, when the refrigerant flowing into the temperature control component 221 is a high-temperature refrigerant, the high-temperature refrigerant will exchange heat with the adsorption substrate 211 and the adsorption coating 212, causing the temperature of the adsorption coating 212 to rise. Once the adsorption coating 212 rises to a certain temperature, it can achieve desorption and regeneration.
[0272] In some embodiments, as shown in FIG27, an airflow channel 213 penetrating the adsorption substrate 211 may be formed on the adsorption substrate 211, and an adsorption coating 212 may be coated on the inner wall of the airflow channel 213.
[0273] In some embodiments, as shown in FIG26, the adsorption substrate 211 may include a first adsorption frame 2111 and an adsorption member 2112 assembled within the first adsorption frame 2111. An airflow channel 213 penetrating the adsorption member 2112 may be provided on the adsorption member 2112. An adsorption coating 212 is coated on the inner wall of the airflow channel 213, and the airflow is adsorbed and purified by the adsorption coating 212 when it flows through the airflow channel 213.
[0274] In some embodiments, as shown in FIG26, the adsorption substrate 211 may include a first adsorption frame 2111 and an adsorption member 2112 assembled within the first adsorption frame 2111. The adsorption member 2112 has a substrate forming surface 214 located on the airflow path of the adsorption substrate 211. An adsorption coating 212 is applied to the substrate forming surface 214.
[0275] In some embodiments, as shown in FIG28, the adsorption substrate 211 may include a second adsorption frame 2113.
[0276] In some embodiments, as shown in FIG28, the adsorption substrate 211 may include adsorption sub-components 2114. Multiple adsorption sub-components 2114 may be provided, and the multiple adsorption sub-components 2114 are assembled on the second adsorption frame 2113. The multiple adsorption sub-components 2114 are parallel to each other and connected. An airflow channel 213 is formed between adjacent adsorption sub-components 2114. The adsorption coating 212 is coated on the outer wall of the adsorption sub-components 2114 constituting the airflow channel 213. When the airflow passes through the airflow channel 213 between the multiple adsorption sub-components 2114, it passes over the outer surface of the multiple adsorption sub-components 2114 and is adsorbed by the adsorption coating 212.
[0277] In some embodiments, as shown in FIG39, an adsorption coating 212 may be applied to the temperature regulating component 221, which can increase the area of the adsorption coating 212, increase the contact area with the airflow, and improve the adsorption effect.
[0278] In some embodiments, as shown in Figures 28 and 29, the temperature control component 221 may be embedded inside the adsorption substrate 211. A bent heat exchange channel 2211 is formed inside the temperature control component 221.
[0279] In some embodiments, as shown in Figures 28 and 29, the adsorption substrate 211 includes a second adsorption frame 2113 and a plurality of adsorption sub-components 2114. The adsorption sub-components 2114 are assembled on the second adsorption frame 2113, and the plurality of adsorption sub-components 2114 are parallel to each other and connected in series by a temperature regulating component 221.
[0280] In some embodiments, as shown in FIG36, the adsorption substrate 211 includes a first adsorption frame 2111 and an adsorption member 2112 assembled within the first adsorption frame 2111. A temperature regulating component 221 is disposed vertically through the adsorption member 2112.
[0281] In some embodiments, the temperature control component 221 may also be attached to the outer surface of the adsorption substrate 211, and it may also exchange heat with the adsorption coating 212 by exchanging heat with the adsorption substrate 211.
[0282] The air conditioner has a temperature-controlled air purification module 200 installed in its airflow path. The module is connected to the refrigeration cycle loop 400 of the air conditioning system through a temperature regulating component 221. The refrigerant in the refrigeration cycle loop 400 is guided to the interior of the temperature regulating component 221 to exchange heat with the adsorption coating 212 on the adsorption substrate 211, thereby achieving temperature regulation of the adsorption coating 212.
[0283] During use, the temperature of the adsorption coating 212 can be lowered during adsorption to improve the adsorption performance of the adsorbed substances in the adsorption coating 212, thereby increasing the adsorption capacity and adsorption efficiency.
[0284] When adsorption is saturated, the temperature of the adsorption coating 212 can be adjusted to raise the temperature of the adsorption coating 212, thereby achieving automatic desorption and regeneration. This completes self-cleaning, extends the service life of the air purification module 200, and eliminates the need for users to frequently disassemble the air purification module 200 to replace the filter, which helps reduce the user's workload and improves the user experience.
[0285] In some embodiments, as shown in Figures 24 and 25, the air conditioner may include a temperature-regulating refrigerant line 405. The temperature-regulating refrigerant line 405 may be arranged in parallel on both sides of the evaporator 404. A temperature-regulating component 221 may be connected to the temperature-regulating refrigerant line 405. Because the temperature-regulating component 221 on the temperature-regulating condenser line is arranged in parallel with the evaporator 404, some of the refrigerant that would normally flow into the evaporator 404 can flow into the temperature-regulating component 221 for heat exchange. During connection, the two ports of the temperature-regulating refrigerant line 405 may be connected to the refrigerant lines located on both sides of the evaporator 404, respectively.
[0286] In some embodiments, the air conditioner may include a temperature control component. The temperature control component can control the temperature of the refrigerant entering the temperature control unit 221 by controlling the degree of its opening.
[0287] In some embodiments, as shown in Figures 24 and 25, the temperature control assembly may include a first throttling component 406. The first throttling component 406 may be disposed on a temperature-regulating refrigerant line 405 near the compressor 401;
[0288] In some embodiments, as shown in Figures 24 and 25, the temperature control assembly may include a second throttling component 407. The second throttling component 407 may be arranged in the temperature-regulating refrigerant circuit near the condenser 402.
[0289] In some embodiments, as shown in Figures 24 and 25, the first throttling component 406 may be a first electronic expansion valve. The second throttling component 407 may be a second electronic expansion valve.
[0290] In some embodiments, as shown in Figures 24 and 25, the first throttling component 406 may be a first throttling valve. The second throttling component 407 may be a second throttling valve.
[0291] In some embodiments, as shown in FIG24, when the air conditioner is running in cooling mode, the refrigerant is compressed by the compressor 401 from low-pressure and low-temperature gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. Then, it flows to the outdoor condenser 402 through the four-way valve 408. The condenser 402 dissipates heat and cools down under the action of the outdoor fan. Then, it becomes a low-temperature and low-pressure state through the throttling action of the main expansion valve 403. It absorbs heat through the indoor evaporator 404, thereby reducing the indoor temperature and achieving the cooling effect.
[0292] During the refrigeration process, a portion of the refrigerant flowing out of the condenser 402 is diverted to the temperature-regulating refrigerant line 405. At this time, the first electronic expansion valve is in the normally open state, and the refrigerant expands and cools down in the temperature-regulating refrigerant line 405 due to the throttling effect of the second electronic expansion valve. It then enters the temperature-regulating component 221 of the air purification module 200. Through heat exchange between the refrigerant in the temperature-regulating component 221 and the adsorption coating 212, the temperature of the adsorption coating 212 is lowered, thereby improving the adsorption capacity.
[0293] In some embodiments, as shown in FIG25, when the air conditioner is in heating mode, the refrigerant is compressed by the compressor 401 from low-pressure and low-temperature gaseous refrigerant to high-temperature and high-pressure gaseous refrigerant. Then, it flows to the evaporator 404 through the four-way valve 408 to dissipate heat to the room. The main expansion valve 403 is fully open, and it becomes a low-temperature and low-pressure state. It absorbs heat through the condenser 402 to achieve the heating effect.
[0294] During the heating process, part of the refrigerant flowing from the compressor 401 enters the evaporator 404, and part enters the temperature control component 221. At this time, the first electronic expansion valve 320 is opened to a small degree, while the second electronic expansion valve is normally open. The refrigerant expands in the temperature control refrigerant pipeline 405 due to the throttling effect of the first electronic expansion valve, and its temperature decreases. It then enters the temperature control component 221, where it exchanges heat with the lower-temperature refrigerant and the adsorption coating 212, thereby lowering the temperature of the air purification module 200 and ensuring good adsorption performance.
[0295] In some embodiments, as shown in Figures 24 and 25, the air conditioner can maintain the adsorption performance of the air purification module 200 by adjusting the opening degree of the temperature control component, regardless of whether it is in cooling or heating mode.
[0296] In some embodiments, the air conditioner may include a temperature and humidity detection component. The temperature and humidity detection component may be arranged at the return air section 110. The temperature and humidity detection component is used to detect the temperature and humidity at the return air section 110 and generate temperature and humidity signals.
[0297] In some embodiments, the temperature and humidity sensing element may include a temperature sensor and a humidity sensor. The temperature and humidity sensing element may be arranged at the return air section 110 for real-time detection of the temperature and humidity at the return air section.
[0298] In some embodiments, as shown in Figures 21 and 30, the air conditioner may include a first odor detection element. The first odor detection element may be arranged on the rear side of the air purification module 200. The first odor detection element can be used to detect a first odor concentration after flowing through the air purification module 200 and generate a first odor concentration signal.
[0299] In some embodiments, the first odor concentration detection element may be a first odor detection sensor, used to detect the odor concentration after the air flows through the air module.
[0300] In some embodiments, as shown in Figures 21 and 30, the air conditioner may include a purification temperature detection element. The purification temperature detection element can be used to detect the temperature of the air purification module 200 and generate a temperature signal for the air purification module 200.
[0301] In some embodiments, the purification temperature detection element is a purification temperature sensor, which detects the temperature of the air purification module 200 in real time.
[0302] In some embodiments, as shown in FIG30, the air conditioner may include a control element. The control element may be configured to: communicate with a temperature and humidity detection element to obtain temperature and humidity signals at the return air section 110, and obtain the dew point temperature of water vapor in the air based on the temperature and humidity signals; the current dew point temperature is obtained by calculation based on temperature and humidity, which can be directly obtained and calculated by those skilled in the art based on their knowledge in the art, and will not be described in detail here.
[0303] In some embodiments, as shown in FIG30, the control element may be configured to communicate with a first odor detection element to obtain a first odor concentration signal.
[0304] In some embodiments, as shown in FIG30, the control element can be configured to communicate with the temperature detection element of the purification module to obtain the temperature signal of the air purification module 200.
[0305] In some embodiments, as shown in FIG30, the control element may be configured to control the operation of the temperature control component based on the acquired first odor concentration signal, the air purification module 200 temperature signal, and the dew point temperature of water vapor in the air.
[0306] After the air conditioner is turned on, the various sensors begin to detect the temperature and humidity at the return air section 110, the concentration of the first odor, and the temperature of the air purification module 200, and transmit the detected signals to the control element that communicates with it in real time.
[0307] The air conditioner controls the first throttling component 406 and the second throttling component 407 accordingly based on the detected temperature and humidity signals, the first odor concentration signal, and the temperature signal of the air purification module 200.
[0308] Let: the first odor concentration be N, the first preset concentration be N1, the temperature at the return air section 110 be T, the humidity be H, the temperature of the air purification block be t, the first odor concentration be N, the dew point temperature of water vapor in the air be T_dew, and the critical dew point temperature be T_dew + 1℃.
[0309] In the initial state of air conditioner operation, the air purification module 200 has good adsorption performance, the odor concentration is relatively low, meeting the usage requirements, and the temperature of the air purification module may not need to be adjusted.
[0310] In some embodiments, the control element may be configured to: when detecting that the first odor concentration is less than the first preset concentration, control the temperature control component to close. That is, when N < N1, the air conditioner operates normally.
[0311] With the accumulation of operation time, pollutants continuously accumulate on the adsorption coating 212, causing the value of the first odor concentration to gradually increase.
[0312] In some embodiments, the control element may be configured to: when detecting that the first odor concentration is greater than the first preset concentration and less than the second preset concentration, repeatedly execute the following control until the temperature of the air purification module 200 is reduced to the critical dew point temperature or reduced to the first temperature.
[0313] Among them, the critical dew point temperature is greater than the dew point temperature. The first temperature corresponds to the temperature that remains unchanged after multiple temperature reductions.
[0314] Let: the second preset concentration be N2. When the first odor concentration satisfies: N1 < N < N2, then the temperature control component needs to be controlled. The specific control is: control the opening degree of the temperature control component to reduce the temperature of the air purification module 200; obtain the dew point temperature of water vapor in the air according to the values of the temperature and humidity detection element, compare the dew point temperature of water vapor in the air with the temperature of the air purification module 200, and when the temperature of the air purification module 200 is greater than the dew point temperature of water vapor in the air, control the temperature control component to operate at this opening degree for a preset time.
[0315] In some embodiments, as shown in Figure 30, when detecting: N1 < N < N2, it means that the odor concentration at the return air part 110 exceeds the first critical value and is less than the second critical value. At this time, the purification ability of the air purification module 200 begins to weaken. The control element then needs to activate the control component and perform corresponding control on the opening degree of the control component to cool down the air purification module 200.
[0316] For the first temperature reduction, first reduce the temperature of the air purification module 200 from the normal temperature t to t1. At the same time, the control element automatically calculates the dew point temperature Tdew of water in the current environment according to the return air temperature T and relative humidity H, and compares it with the temperature t1. If the temperature t1 of the air purification module 200 is higher than the dew point temperature Tdew + 1°C, maintain this state and continue to operate for 10 - 20 minutes.
[0317] After a preset time, the first odor concentration N at the rear end of the air purification module 200 is detected again. If the first odor concentration is still within the range of N1 to N2, the control element continues to adjust the temperature of the air purification module 200 to t2, where t2 < t1, and calculates the dew point temperature Tdew of the water vapor in the air again for comparison and judgment, and runs for a preset time of 10 - 20 min.
[0318] If the dew point temperature is not reached, the air purification module 200 is continuously cooled down to t3, where t3 < t2, and after running for a preset time, it is compared with the current dew point temperature Tdew again for judgment, and the cycle continues until the temperature of the air purification module 200 is reduced to the critical dew point temperature and then no longer continues to decrease.
[0319] In some embodiments, t1, t2, and t3 change in a certain gradient. By having t1, t2, and t3 change in a certain gradient, it is possible to prevent the temperature of the air purification module 200 from being lower than the dew point temperature of the water in the air in the current state, and thus condensate is generated on the surface of the air purification module 200. If water vapor condenses on the air purification module 200, it will occupy the microporous structure of the adsorption material, thereby greatly reducing the adsorption performance of the adsorption material, and further reducing the purification effect of the air purification module 200.
[0320] Therefore, the dew point temperature in the current state is calculated from the temperature and humidity of the air at the return air outlet, and compared with the temperature of the air purification module 200, and then the temperature of the air purification module 200 is controlled to approach the dew point temperature of the water vapor in the air.
[0321] If it is detected that the first odor concentration is still within the range of N1 < N < N2 after the air purification module 200 has been continuously cooled down to the first temperature, it means that the environmental dew point temperature is relatively low at this time and cooling cannot continue. The control element directly controls the air purification module 200 to operate at the lowest achievable first temperature until the first odor concentration N > N2 of the air purification module 200, and then automatically enters the N > N2 control mode.
[0322] In some embodiments, the control element can be configured to: when detecting that the first odor concentration signal is greater than the second preset concentration, control the opening degree of the temperature control component so that the temperature of the air purification module 200 is reduced to the critical dew point temperature.
[0323] When it is detected that the first odor concentration is greater than the second preset concentration, the air purification module 200 can be directly controlled to be reduced to the critical dew point temperature by controlling the control component.
[0324] In some embodiments, when the control element cannot reduce the temperature of the air purification module 200 to the critical dew point temperature by controlling the control component, it indicates that the ambient dew point temperature is relatively low at this time. The control element can directly control the air purification module 200 to operate at the lowest achievable temperature, i.e., the first temperature.
[0325] In some embodiments, the air conditioner has a heating operation mode. When in the heating operation mode, the control element is configured to:
[0326] When it is detected that the first odor concentration is less than the first preset concentration, control the first throttle component 406 to close and the second throttle component 407 to close.
[0327] When it is detected that the first odor concentration signal is greater than the first preset concentration and less than the second preset concentration, the control element controls the temperature control component to turn it on and start adjusting the temperature of the air purification module 200.
[0328] When the control component is initially turned on, the second throttle component 407 is in the fully open state and the first throttle component 406 is fully open.
[0329] Then, the control element controls the opening degree of the first throttle component 406 to decrease it, so as to reduce the temperature of the air purification module 200 to t1.
[0330] The control element obtains the dew point temperature of the water vapor in the air and the temperature of the air purification module 200 based on the temperature and humidity, and compares them. When it is obtained that the temperature of the air purification module 200 is higher than the critical dew point temperature, the control element controls the first throttle component 406 and the second throttle component 407 to operate at this opening degree for a preset time.
[0331] After running for the preset time, the first odor concentration is detected again. If the first odor concentration still remains between N1 < N < N2, the control element loops to execute the above control.
[0332] When the control element detects that the first odor concentration signal is greater than the second preset concentration, it controls the opening degree of the first throttle component 406 to decrease, so as to reduce the temperature of the air purification module 200 to the critical dew point temperature.
[0333] Alternatively, the opening degree of the first throttle component 406 is controlled to the minimum opening degree, so as to make the air purification module 200 operate at the first temperature.
[0334] In some embodiments, the air conditioner has a cooling operation mode. When in the cooling operation mode, the control element is configured to:
[0335] When it is detected that the first odor concentration is less than the first preset concentration, control the first throttle component 406 to close and the second throttle component 407 to close.
[0336] When it is detected that the first odor concentration is greater than the first preset concentration and less than the second preset concentration, the control element controls the temperature control component to start, and starts to adjust the temperature of the air purification module 200.
[0337] When the control component is turned on, the second throttle component 407 is fully open, and the first throttle component 406 is fully open.
[0338] Then, the control element controls the opening degree of the second throttle component 407 to decrease, so that the air purification module 200 is cooled to t1.
[0339] The control element obtains the dew point temperature of the water vapor in the air at the return air side and the temperature of the air purification module 200 according to the temperature and humidity of the return air side and compares them. When it is obtained that the temperature of the air purification module 200 is higher than the critical dew point temperature, the control element controls the second throttle component 407 and the first throttle component 406 to operate at this opening degree for a preset time.
[0340] After running for the preset time, the first odor concentration is detected again. If the first odor concentration is still between N1 < N < N2, the control element will execute the above control in a loop.
[0341] When the control element detects that the first odor concentration signal is greater than the second preset concentration, it controls the opening degree of the second throttle component 407 to decrease, so that the temperature of the air purification module 200 is reduced to the critical dew point temperature.
[0342] Alternatively, the opening degree of the second throttle component 407 is controlled to the minimum opening degree, so that the air purification module 200 operates at the first temperature.
[0343] In some embodiments, the air conditioner may include a second odor detection element. The second odor detection element is used to detect the odor concentration at the return air part 110 and generate a second odor concentration signal. The second odor detection element is a second odor detection sensor, and it detects the second odor concentration before flowing through the air purification module 200.
[0344] In some embodiments, the control element may be configured to communicate with the second odor concentration detection element to obtain the second odor concentration. When the difference between the second odor concentration and the first odor concentration is greater than the odor preset value, the control element controls the air conditioner to maintain its original state of operation.
[0345] Let: the odor preset value be C1, and the difference between the second odor concentration and the first odor concentration be C.
[0346] The difference C = M - N between the second odor concentration M before flowing through the air purification module 200 and the first odor concentration N after flowing through the air purification module 200.
[0347] If the value of C is greater than the set value C1, it indicates that the adsorption performance of the air purification module 200 is good under the current state. The main reason for the relatively high outlet concentration N is that the odor concentration M at the inlet is too high, exceeding the purification capacity of the air purification module 200. Under such conditions, the system will maintain the current operating state and continue to run.
[0348] When the difference between the second odor concentration and the first odor concentration is less than the preset odor value, a desorption prompt signal is sent.
[0349] When C < C1, it is determined that the adsorption capacity of the air purification module 200 is saturated, and the control element can send a desorption prompt signal to notify the user that it is saturated.
[0350] In some embodiments, the control element can also send a request of "whether to enter the desorption mode" to the user client. If the user agrees, the desorption mode is entered; if the user does not agree, the current operating state is maintained, and a reminder is given when the unit is powered on next time.
[0351] In some embodiments, as shown in FIG. 22, the air conditioner may include a desorption air duct member 610. The desorption air duct member 610 can be connected to the housing 100, and a desorption air duct 611 is formed inside it. The desorption air duct 611 is communicated with the heat exchange air duct 130.
[0352] In some embodiments, as shown in FIG. 22, the desorption air duct member 610 can be connected to the side or the top of the housing 100.
[0353] In some embodiments, as shown in FIG. 22, an interface portion penetrating through the housing 100 can be provided on the housing 100. The desorption air duct member 610 can be installed at the interface portion to achieve docking with the heat exchange air duct 130 inside the housing 100.
[0354] In some embodiments, as shown in FIG. 22, the air conditioner may include a desorption fan 620. The desorption fan 620 can be arranged in the desorption air duct 611. The desorption fan 620 can be used to drive the air flow to flow in the heat exchange air duct 130 and the desorption air duct 611. The desorption fan 620 can provide the power for the air flow to flow between the heat exchange air duct 130 and the desorption air duct 611, and control the air flow direction to ensure that when thermally desorbing, the gas volatilized from the air purification module 200 can be driven to be discharged outwards from the desorption air duct 611.
[0355] In some embodiments, as shown in FIG. 22, the air conditioner may include a valve 630. The valve 630 is connected to the connection between the desorption air duct member 610 and the housing 100 in an openable and closable manner. The valve 630 can be used to separate or connect the desorption air duct 611 and the housing 100.
[0356] In some embodiments, the valve 630 may be an opening and closing valve 630 structure of the related technology. The valve 630 is arranged at the interface and can be moved to open or close the interface.
[0357] In some embodiments, as shown in FIG22, when the valve 630 opens the interface, the desorption duct 611 is connected to the heat exchange duct 130, and the air purification module 200 can be desorbed at this time.
[0358] In some embodiments, as shown in FIG22, when the valve 630 moves to close the interface, the desorption duct 611 and the heat exchange duct 130 are separated from each other, and the heat exchange duct 130 can perform normal heat exchange without interfering with each other.
[0359] In some embodiments, the control element may be configured to: when receiving a desorption control command, control the air supply device 300 and the air outlet 120 to close, control the valve 630 to open, and control the desorption fan 620 to start; control the air conditioner to enter the heating operation mode, and control the first throttling component 406 to be fully open.
[0360] When the odor concentration detection element at the back end of the air purification module 200 detects a value exceeding the limit, the control element will issue an alarm. The user will then issue a desorption control command, specifically through a user client connected to the air conditioner or a remote control. Upon receiving the desorption control command, the control element will activate the relevant controls for the desorption operation mode.
[0361] The control element will simultaneously close the air outlet 120 and the air supply device 300, and open the valve 630 and the desorption fan 620 to switch the air conditioner to heating mode.
[0362] At this time, part of the refrigerant entering from the compressor 401 enters the evaporator 404 to release heat, and part enters the temperature control component 221. The high-temperature refrigerant entering the temperature control component 221 will exchange heat with the air purification module 200 to raise the temperature of the adsorbed substances in the air purification module 200. The adsorption coating 212 is desorbed and regenerated through high temperature. The air purification module 200 is heated, and the odor substances adsorbed inside are re-evaporated and located in the heat exchange duct 130. Since the air outlet 120 is closed, the adsorption fan and adsorption duct are opened. When the adsorption fan rotates, it will drive the airflow inside the heat exchange duct 130 into the adsorption duct. The re-evaporated odor gas is discharged outdoors through the desorption duct 611 under the drive of the desorption fan 620.
[0363] In some embodiments, the air purification module 200 may include an auxiliary heating module, which may be mounted on the adsorption substrate 211.
[0364] In some embodiments, the control element may be configured to: acquire the temperature of the air purification module 200 during the execution of the desorption command, and control the opening and closing of the auxiliary heating module according to the temperature of the air purification module 200.
[0365] In some embodiments, the auxiliary heating module is mainly used in conjunction with the temperature control component 221 to increase the temperature of the air purification module 200. If the air purification module 200 cannot reach the desorption temperature by relying solely on the refrigerant, the auxiliary heating module can be turned on to assist.
[0366] In some embodiments, the auxiliary heating module may be a heating wire or a heating tube, and it may be embedded inside the adsorption substrate 211.
[0367] In some embodiments, the control element may be configured to: control the auxiliary heating module to turn on when the temperature of the air purification module 200 is detected to be lower than the first preset temperature; and control the auxiliary heating module to turn off when the temperature of the air purification module 200 is detected to be higher than the first preset temperature.
[0368] During the process of the temperature control component 221 heating the air purification module 200 with refrigerant, the temperature of the purification module is simultaneously monitored by the temperature detection element of the purification module. When the required first preset temperature cannot be reached by relying solely on refrigerant heating, the auxiliary heating module is activated to assist in heating.
[0369] In some embodiments, the control element may be configured to: during the execution of the desorption command, acquire the first odor concentration value of the first odor detection element, and when the concentration of the first odor detection element is detected to be less than the preset odor concentration, control the valve 630 to close and the desorption fan 620 to close.
[0370] During the process of the temperature control component 221 heating the air purification module 200 with refrigerant, the concentration of the first odor at the back end of the air purification module 200 is monitored in real time. When the concentration of the first odor decreases to the preset odor concentration, it indicates that the odor substance has been completely removed and the desorption process ends. The system control then returns to the operating state before the desorption mode.
[0371] Air conditioner indoor units typically have filters installed at the return air vent or inside the unit casing to purify indoor air. During installation, multiple centrifugal fans are placed inside the casing. Between adjacent centrifugal fans, where there is no volute to block the airflow, a high-velocity zone is formed, while the corresponding area with the volute forms a low-velocity zone. This results in uneven airflow through the filter. Especially in the high-velocity zones, the excessively high airflow makes it difficult to effectively capture odor molecules, leading to a lower purification rate in these areas. Consequently, the filter cannot truly exert its purification effect, resulting in uneven purification and poor overall purification performance.
[0372] To address the aforementioned technical problems, an air conditioner is proposed in some embodiments. The air conditioner in this disclosure performs a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space. A low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
[0373] In some embodiments, the expansion valve expands the high-temperature, high-pressure liquid refrigerant that has condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.
[0374] In some embodiments, the outdoor unit of an air conditioner refers to the portion of the refrigeration cycle that includes a compressor and an outdoor heat exchanger. The indoor unit of an air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in either the indoor or outdoor unit.
[0375] In some embodiments, the indoor heat exchanger and the outdoor heat exchanger serve as either a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger serves as an evaporator, the air conditioner functions as a cooler in cooling mode.
[0376] In some embodiments, as shown in FIG31, the indoor unit may include a housing 100 and a return air section 110 and an air outlet section 120 disposed on the housing 100. The return air section 110 is formed on the housing 100 and is used to introduce airflow into the housing 100. The return air section 110 may be a return air vent formed on the housing 100, which serves to introduce airflow. The air outlet section 120 is formed on the housing 100 and is used to lead airflow out of the housing 100. An airflow channel 160 is formed between the air inlet section, the air outlet section 120, and the housing 100. The air outlet section 120 may be an air outlet. The air outlet section 120 may be formed on the housing 100 and may be disposed opposite to the return air vent, for discharging airflow from the housing 100 to the indoor unit.
[0377] In some embodiments, as shown in FIG31, the housing 100 may constitute the housing of an air conditioner. The interior of the housing 100 is used to house the indoor heat exchanger 140 and the air supply device 300.
[0378] In some embodiments, as shown in FIG31, the indoor heat exchanger 140 can be used to exchange heat with air, reducing the temperature of the airflow exiting the outer casing 100. The indoor heat exchanger 140 is arranged sequentially with the air supply device 300 along the airflow direction.
[0379] In some embodiments, as shown in FIG31, the air supply device 300 can be used to provide power to drive the airflow. When the air supply device 300 is running, it can draw in air from the return air section 110 and send it to the indoor heat exchanger 140 for heat exchange, and send the airflow cooled by heat exchange in the indoor heat exchanger 140 from the air outlet section 120, so as to achieve the effect of driving the airflow to flow and be transported in the airflow channel 160 between the return air section 110, the air outlet section 120 and the outer casing 100.
[0380] In some embodiments, as shown in FIG31, the air conditioner may include a filter element 500. The filter element 500 may be mounted on the housing 100. The filter element 500 may be located on the airflow channel 160. The filter element 500 is arranged on the airflow channel 160 flowing through the air conditioner to ensure that it can filter, adsorb and purify the airflow flowing through the air conditioner.
[0381] In some embodiments, as shown in FIG31, the filter element 500 may be disposed at the return air section 110, at the air outlet section 120, or inside the housing 100. The filter element 500 may also be disposed between the indoor heat exchanger 140 and the air supply device 300. All of the above arrangements can ensure that the airflow drawn into the housing 100 can pass through the filter element 500.
[0382] In some embodiments, as shown in Figures 32 and 33, an airflow channel 510 is formed inside the filter element 500, which extends through the filter element 500 along the airflow direction, and an adsorption and purification substance is coated inside the airflow channel 510.
[0383] By arranging the airflow channel 510 to pass through the filter component 500 along the airflow direction, the airflow can pass through the internal airflow channel 510 when it passes through the filter component 500, thereby ensuring that the airflow can fully contact the adsorbed and purified substances in the airflow channel 510 to achieve the filtration effect.
[0384] In some embodiments, as shown in FIG31, a first wind speed zone 310 and a second wind speed zone 320 are formed at the location of the air supply device 300. The air supply device 300 can be a centrifugal fan with a volute casing on its exterior. Multiple air supply devices 300 can be provided, and the multiple air supply devices 300 can be arranged side by side along the length direction of the return air section 110. Since there is no volute casing to obstruct the air supply devices 300, a first wind speed zone 310 is formed between them. A second wind speed zone 320 is formed in the area surrounding the first wind speed zone 310, such as the area behind the volute casing.
[0385] In some embodiments, as shown in Figures 31 and 32, the wind speed in the first wind speed zone 310 is higher than the wind speed in the second wind speed zone 320. The first wind speed zone 310 corresponds to the high wind speed zone, and the second wind speed zone 320 corresponds to the low wind speed zone.
[0386] Due to the structure of the air supply device 300 inside the air conditioner, a first wind speed zone 310 and a second wind speed zone 320 with different wind speeds are formed in the area of the air supply device 300. Different wind speed zones correspond to different wind speeds, and the driven flow speed is also different when the airflow corresponds to different wind speed zones.
[0387] If the airflow is drawn in and corresponds to the position of the first wind speed zone 310, the wind speed in the first wind speed zone 310 is high, and the airflow will quickly flow through the filter component 500.
[0388] If the airflow corresponds to the position of the second wind speed zone 320, and the wind speed in the second wind speed zone 320 is low, the airflow will flow through the filter component 500 more slowly.
[0389] As the airflow at position 310 in the first wind speed zone flows rapidly through the filter element 500, the adsorbent in the filter element 500 cannot effectively capture odor molecules in the airflow, resulting in a low purification rate in the high wind speed area, uneven purification, and unsatisfactory purification effect.
[0390] Based on the above problems, in some embodiments, as shown in Figures 31 and 32, an air conditioner is proposed that improves the structure of the filter component 500 by setting the length of the airflow channel 510 corresponding to the position of the filter component 500 and the first wind speed zone 310 to be greater than the length of the airflow channel 510 corresponding to the position of the second wind speed zone 320.
[0391] By setting the airflow channel 510 in the filter component 500 corresponding to the first wind speed zone 310 to be longer than the airflow channel 510 corresponding to the second wind speed zone 320, the flow path of the airflow in the first wind speed zone 310 can be extended accordingly. This allows the airflow in the first wind speed zone 310 to fully contact the adsorbed material inside the airflow channel 510, improving the filtration and purification effect of the filter component 500 in the first wind speed zone 310, ensuring the uniformity of filtration, improving the utilization rate of each part of the filter component 500, and fully utilizing the purification capacity of the filter component 500.
[0392] In some embodiments, as shown in Figures 31 and 32, the filter component 500 may include a first filter section 520, which may correspond to the position of the first wind speed zone 310.
[0393] In some embodiments, as shown in Figures 31 and 32, the filter element 500 may include a second filter section 530. The second filter section 530 may correspond to the position of the second wind speed zone 320.
[0394] In some embodiments, as shown in Figures 31 and 32, the thickness of the first filter section 520 in the airflow direction can be greater than the thickness of the second filter section 530 in the airflow direction. By increasing the thickness of the first filter section 520 at the corresponding location in the first wind speed zone 310, the length of the airflow channel 510 within the first filter section 520 in the first wind speed zone 310 can be increased, thereby ensuring that the airflow in the first wind speed zone 310 can fully contact the adsorbed substances within the airflow channel 510, thus ensuring the adsorption and purification effect in the high wind speed zone.
[0395] In some embodiments, as shown in FIG31, when the filter element 500 is located at the return air section 110 or the air outlet section 120, the outer surfaces of the first filter portion 520 and the second filter portion 530 of the filter element 500 are flush. The inner surface of the first filter portion 520 protrudes relative to the inner surface of the second filter portion 530. The protruding portion of the first filter portion 520 can be located inside the housing 100, which ensures good aesthetics after overall installation.
[0396] In some embodiments, as shown in FIG31, the airflow channels 510 on the first filter section 520 and the second filter section 530 have the same shape and size. When the thickness of the first filter section 520 is greater than the thickness of the second filter section 530, if the shapes of the airflow channels 510 in the first filter section 520 and the second filter section 530 are different, the length of the flow path of the airflow as it flows through the airflow channels 510 will change, and the length of the airflow channel 510 in the first filter section 520 will be shorter than that in the second filter section 530. By setting the shape and size of the airflow channels 510 on both filter sections to be the same, it can be ensured that the airflow channel 510 of the thicker filter section has a longer path, resulting in a longer contact time with the airflow and more sufficient contact.
[0397] In some embodiments, as shown in FIG32, the airflow channel 510 in the first filter section 520 can be a bent channel arranged in a bend along the airflow direction. The airflow channel 510 in the second filter section 530 can be a straight channel with its axis perpendicular to the filter component 500.
[0398] In some embodiments, as shown in Figure 32, the bend channel can be an arc-shaped channel, a bend channel with multiple wave segments, or a curved channel. A straight channel has a shorter airflow path compared to a bend channel.
[0399] In some embodiments, as shown in FIG32, the first filter section 520 is provided with a bent channel arranged in a bent manner. The bent channel can extend the path length of the airflow within it, so that the airflow can have more sufficient contact with the adsorbent material arranged in the airflow channel 510. When the thickness of the first filter section 520 is greater than the thickness of the second filter section 530, by providing a bent channel in the first filter section 520 and a straight channel in the second filter section 530, the length of the airflow channel 510 in the first filter section 520 is further extended, further ensuring that the airflow flowing through the first wind speed zone 310 can have sufficient contact with the adsorbent material.
[0400] In some embodiments, as shown in FIG31, the filter component 500 may include a first filter section 520 and a second filter section 530. The first filter section 520 may correspond to the position of the first wind speed zone 310. The second filter section 530 may correspond to the position of the second wind speed zone 320.
[0401] In some embodiments, the thickness of the first filter portion 520 and the second filter portion 530 may be equal to the thickness of the second filter portion 530.
[0402] In some embodiments, as shown in FIG32, the airflow channel 510 of the first filter section 520 is a bent channel arranged along the airflow direction, and the second filter section 530 is a straight channel with its axis perpendicular to the filter component 500.
[0403] When the thickness of the first filter section 520 and the thickness of the second filter section 530 are the same, if the airflow channel 510 in the first filter section 520 is set as a bent channel and the second filter section 530 is set as a straight channel, then since the length of the bent channel is greater than the length of the straight channel, it can also be ensured that the length of the airflow channel 510 in the first filter section 520 is greater than the length of the airflow channel 510 in the second filter section 530, which can ensure that the airflow can fully contact the first wind speed zone 310.
[0404] In some embodiments, as shown in Figures 31 and 32, the filter component 500 may include a first filter section 520 and a second filter section 530. The first filter section 520 may correspond to the position of the first wind speed zone 310. The second filter section 530 may correspond to the position of the second wind speed zone 320. The airflow channel 510 of the first filter section 520 may be a bent channel arranged along the airflow direction. The airflow channel 510 of the second filter section 530 may be a straight channel with its axis perpendicular to the filter component 500. When the thickness of the first filter section 520 and the thickness of the second filter section 530 are the same, by setting the airflow channel 510 in the first filter section 520 in the form of multiple bent segments, it is also possible to achieve the effect that the length of the airflow channel 510 in the first filter section 520 is greater than the length of the airflow channel 510 in the second filter section 530.
[0405] In some embodiments, as shown in Figures 31 and 32, the filter component 500 may include a first filter section 520 and a second filter section 530. The first filter section 520 corresponds to the position of the first wind speed zone 310. The second filter section 530 corresponds to the position of the second wind speed zone 320. The cross-sectional area of the airflow channel 510 in the first filter section 520 is less than or equal to the cross-sectional area of the airflow channel 510 in the second filter section 530.
[0406] When airflow passes through the filter element 500, the different cross-sectional areas of the airflow channels 510 it passes through will change its flow speed. By setting the cross-sectional area of the airflow channel 510 of the first filter element 520, which corresponds to the high-speed zone, to be smaller than the cross-sectional area of the airflow channel 510 at the second filter element 530, the airflow can be throttled and slowed down when passing through the airflow channel 510 of the first filter element 520. This reduces the speed of the airflow passing through the first filter element 520, allowing the airflow to fully contact the adsorbent in the airflow channel 510 to capture odor molecules, ensuring purification uniformity, achieving full contact between the airflow and the entire filter element 500, and improving the overall purification effect.
[0407] In some embodiments, as shown in Figures 31 and 32, the filter element 500 may include a filter screen. The filter screen may include a plurality of filter sections that may be sequentially hinged together. The plurality of filter sections may include at least one first filter section 520 corresponding to the first wind speed zone 310 and at least one second filter section 530 corresponding to the second wind speed zone 320.
[0408] In some embodiments, as shown in FIG32, when connected, two adjacent first filter sections 520 can be hinged to each other. A second filter section 530 located adjacent to the first filter section 520 is hinged to the first filter section 520. Two adjacent second filter sections 530 can be hinged to each other. By configuring the filter sections to be hinged together, during assembly and disassembly, a force can be applied to any one of the filter sections to move the sequentially hinged filter sections, facilitating the assembly and disassembly of the filter component 500.
[0409] In some embodiments, as shown in FIG32, two first filter sections 520 may be provided, and the two first filter sections 520 may be hinged to each other. Two second filter sections 530 may be provided, and the two second filter sections 530 may be symmetrically arranged on both sides of the two first filter sections 520, and respectively hinged to the first filter section 520 on the corresponding side.
[0410] In some embodiments, as shown in Figures 32 and 33, the filter component may include a mounting frame 40. The mounting frame 40 can be fitted to the return air section 110 or the outlet air section 120, and is used to mount the filter screen. Fixed to the periphery of the return air section 110 and the outlet air section 120 by the mounting frame 40, when the filter component 500 is mounted on the mounting frame 40, it can block the return air section 110 or the outlet air section 120 to filter the airflow.
[0411] In some embodiments, as shown in Figures 32 and 33, the mounting frame 40 may include a frame body portion 410. The frame body portion 410 is a frame, and a hollow space is formed inside the frame body portion 410 to arrange the filter component 500.
[0412] In some embodiments, as shown in Figures 32 and 33, the mounting frame 40 may include a frame sliding stop 420. A sliding limiting portion may be formed between the sliding stop 420 and the frame body portion 410.
[0413] In some embodiments, the sliding limiter is configured to guide the filter component 500 during assembly. After the filter component 500 is assembled, it limits the filter component 500 to prevent it from falling off after installation.
[0414] During the installation of the filter component 500, the filter component 500 can be installed and fixed by sliding along the sliding limit part after being inserted into it. After the filter component 500 is assembled, part of the filter part is located in the sliding limit part. The sliding limit part limits part of the filter part, thereby limiting the entire filter component 500.
[0415] When the filter element 500 needs to be disassembled or assembled, the filter element located in the sliding limit part is moved by the filter element not in the sliding limit part to disengage from the sliding limit part.
[0416] During disassembly, force can be applied to one of the filter parts that is not in the sliding limit part, drag it to move, thereby moving the remaining filter parts that are hinged to it, dragging the filter parts in the sliding limit part to gradually separate from the sliding limit part, and finally achieving the effect of detaching from the entire mounting frame 40.
[0417] By configuring the filter component 500 as a structure in which multiple filter parts are hinged together, some filter components 500 can be rotated and folded together during the initial assembly of the filter component 500. During the assembly of the filter component 500, the folded filter parts can be rotated and unfolded, so that the filter component 500 can be quickly assembled onto the mounting frame 40 along the sliding limit portion formed on the mounting frame 40 when unfolded, which facilitates the installation of the filter component 500.
[0418] When the filter component 500 is disassembled, a force is applied to one of the filter components that is not in the sliding limit part. This filter component drives the remaining filter components that are hinged to each other to move, so that the filter component 500 can be easily pulled out of the mounting frame 40.
[0419] In some embodiments, a drag rope is provided on one of the filter parts not within the sliding limit portion, which facilitates dragging the filter component 500.
[0420] In some embodiments, as shown in Figures 32 and 33, the first wind speed zone 310 may correspond to at least one of the positions of the first filter section 520. The second wind speed zone 320 may correspond to at least one of the positions of the second filter section 530. When the filter component 500 is provided, one or more first filter sections 520 may be provided to correspond to the position of the first wind speed zone 310, and one or more second filter sections 530 may be provided to correspond to the position of the second wind speed zone 320.
[0421] In some embodiments, as shown in FIG40, the frame body portion 410 may have a first side portion 411 facing the user and a second side portion 412 disposed opposite to the first side portion 411. The second side portion 412 is disposed facing the internal space of the housing. The first side portion 411 may be the front side portion of the frame body portion 410, and the second side portion 412 may be the rear side portion of the frame body portion 410.
[0422] In some embodiments, as shown in Figures 36 and 40, the sliding stop 420 may include a first sliding stop 421. The first sliding stop 421 may be disposed on the first side surface 411 to limit the movement of the filter screen in the front side direction.
[0423] In some embodiments, as shown in Figures 38 and 40, the sliding stop 420 may include a second sliding stop 422. The second sliding stop 422 may be disposed on the second side surface portion 412 to limit the rear side surface direction of the filter.
[0424] The first sliding stop 421 and the second sliding stop 422 provided on both sides of the frame body 410 cooperate with each other to ensure that the filter component 500 is firmly limited and fixed, preventing it from falling off.
[0425] In some embodiments, as shown in FIG38, the frame body portion 410 may include a first border portion 415. The first border portion 415 may be used to support the filter screen;
[0426] In some embodiments, as shown in Figures 38 and 39, the frame body portion 410 may include a second frame portion 416, which may be used to limit the end of the filter screen. The second frame portion 416 may be located above the first frame portion 415. The second frame portion 416 may be connected to the first frame portion 415.
[0427] In some embodiments, as shown in Figures 38 and 39, the first frame portion 415 can be a support frame portion. The second frame portion 416 can be a side frame portion.

[0429] In some embodiments, as shown in Figures 36 and 38, a first sliding stop 421 may be disposed at a first frame portion 415, which can be used to limit the stop of the filter screen and ensure the sliding installation of the filter screen. The first sliding stop 421 is a first flange portion or a first limiting stop member.
[0430] In some embodiments, as shown in Figures 36 and 38, a first sliding stop 421 is disposed on the second frame portion 416, and may be disposed at the end or middle position of the second frame portion 416.
[0431] In some embodiments, as shown in Figures 36 and 38, the first sliding stop 421 is simultaneously disposed on the first frame portion 415 and the second frame portion 416.
[0432] In some embodiments, as shown in Figures 38 and 39, the frame body portion 410 may include a first border portion 415. Two first border portions 415 are provided and are arranged opposite to each other. The first border portions 415 constitute the length border of the frame body, and a plurality of filter portions are arranged side by side along the length direction of the first border portions 415.
[0433] In some embodiments, as shown in Figures 38 and 39, the frame body portion 410 may include a second border portion 416, which constitutes the width border of the frame body. The length of the second border portion 416 is less than that of the first border portion 415. Two second border portions 416 are provided, which are arranged opposite to each other, and both ends of the second border portion 416 are respectively connected to the two first border portions 415.
[0434] In some embodiments, as shown in Figures 36 and 38, the first sliding stop 421 may include a first side 4211, and two first side 4211 may be provided. The two first side 4211 may be formed at the end positions of the two first frame portions 415 respectively, and the length of the first side 4211 is less than that of the first frame portion 415.
[0435] In some embodiments, as shown in Figures 36 and 38, the first edge 4211 is a first flange, which extends from the first frame portion 415 and has a relatively short length.
[0436] In some embodiments, as shown in Figures 36 and 38, the first sliding stop 421 may include a second side portion 4212. Two second side portions 4212 may be provided. The two second side portions 4212 are respectively formed on two second side portion 416. The second side portion 4212 may extend along the length direction of the second side portion 416 from one end of the second side portion 416 to the other end of the second side portion 416, and both ends of the second side portion 4212 may be connected to the two first side portions 4211 respectively.
[0437] In some embodiments, as shown in Figures 36 and 38, the second side 4212 can be a second flange, the length of the second side 4212 is the same as the length of the second border, and it is folded from the second border to form the flange.
[0438] In some embodiments, the second sliding stop 422 and the first sliding stop 421 may have the same structure, and the second sliding stop 422 and the first sliding stop 421 may be symmetrically arranged on both sides of the frame body 410.
[0439] In some embodiments, as shown in FIG38, the second sliding stop 422 may be a circumferential flange arranged around the frame body portion.
[0440] During installation, multiple filter units can be folded at the middle position, and then the filter units at both ends can be inserted into the positions between the first side 4211, the second sliding stop 422, and the first frame 415 at both ends of the mounting frame 40. The folded filter units are then continuously unfolded by relative rotation, thereby pushing the filter units inserted between the first side 4211, the first frame 415, and the second sliding stop 422 to slide closer to the second side 4212 until one end of the filter unit at the end slides into the space formed by the second side 4212, the second sliding stop 422, and the second frame 416, and part of the filter unit is still limited and fixed in the space between the first side 4211, the first frame 415, and the second sliding stop 422.
[0441] During disassembly, force is applied to the filter part that is not in the sliding limit part, pulling it to slide along the length direction of the first frame part 415, causing the filter part located in the sliding limit part to slide out along the direction of the first frame part 415.
