Description
[0001] AIR TREATMENT DEVICE FOR A ROOM
[0002] Scope of the invention
[0003] The invention relates to the field of air treatment such as air conditioning.
[0004] More specifically, the invention relates to the field of air treatment devices such as air conditioning devices for cooling a room.
[0005] State of the art
[0006] In prior art, we know of air conditioning devices adapted to cool a room.
[0007] Such devices are commonly used to maintain a comfortable temperature in indoor spaces, such as a living room in an apartment.
[0008] For example, prior art has shown air conditioning systems including a heat pump, such as an air-to-air type heat pump.
[0009] Such air conditioning systems utilize a refrigerant circulating in a closed loop between an indoor unit and one or more outdoor units.
[0010] One drawback of these air conditioning systems is that they require significant installation work, including drilling through walls for the installation of circuits and outdoor units.
[0011] Another drawback of these air conditioning systems is their high energy consumption.
[0012] Another drawback of these air conditioning systems is that they accentuate the urban heat island effect by releasing heat.
[0013] Another drawback of these air conditioning systems stems from the environmental impact of using a refrigerant gas.
[0014] Another drawback of these air conditioning systems stems from their lack of compactness, making them unsuitable for integration into confined spaces.
[0015] Prior art also includes so-called "adiabatic" air conditioning systems, which cool the air by evaporation. Although such air conditioners are more energy-efficient and environmentally friendly than conventional air conditioners, they have several drawbacks.
[0016] On the one hand, the evaporative cooling of the air in such systems leads to an increase in the humidity level in the room to be air-conditioned, which contributes to discomfort for people present in the room, can lead to respiratory problems for people sensitive to humidity or promote the formation of mold.
[0017] We are also familiar with document GB2493228A, which is partially integrated into a chimney. A drawback of this type of system is that it requires the installation of a heat exchanger outside the building and necessitates structural work for the passage of ducts from the heat exchanger to the inside of the system.
[0018] Another drawback of existing adiabatic air conditioning systems stems from their lack of energy efficiency.
[0019] Another drawback of existing adiabatic air conditioning systems stems from their lack of compactness, making them also unsuitable for integration into confined spaces.
[0020] Another drawback of existing adiabatic air conditioning systems is that their installation also requires significant work.
[0021] The invention aims at least to limit the aforementioned disadvantages.

[0060] According to another aspect, the invention relates to a room containing an air conditioning device.
[0061] According to another aspect, the invention relates to a building comprising a plurality of premises including an air conditioning device.
[0062] In another aspect, the invention relates to an air conditioning device comprising:
[0063] • an air inlet cooperating with a first fan allowing to extract and direct a primary airflow from a first zone located outside the room towards a heat exchanger;
[0064] • the heat exchanger humidifying said primary airflow to generate at least one humid airflow from a passage of the primary airflow through the heat exchanger, and comprising at least one air outlet to guide said humid airflow to at least one condensation module;
[0065] • a primary water circuit, • the condensation module condensing a volume of water contained in said humid airflow to generate a volume of condensed water, said condensation module having a water outlet leading to a water inlet of said primary water circuit.
[0066] One advantage is that it allows for the recycling of a volume of condensed water from the humid airflow.
[0067] According to one embodiment, the heat exchanger is configured to cool the primary airflow to generate a cooled airflow, and configured to humidify at least a portion of the cooled airflow to generate a portion of humid air, said portion of humid air being directed to said condensation module.
[0068] In one embodiment, the heat exchanger comprises a plurality of primary channels, called "dry channels," through which the primary airflow circulates, and a plurality of secondary channels arranged circumferentially around each primary channel, called "wet channels." The secondary channels are delimited by a first portion of aluminum fins, a second portion of which extends into the primary channels. A porous mineral material, irrigated by a volume of water, is arranged in contact with the fins delimiting the secondary channels. A volume of water from the water circuit evaporates on the surface of the porous mineral material, which cools, thereby cooling the airflow circulating in the primary channels by heat transfer through the fins arranged, on one side, in contact with the airflow circulating in the primary channels, and on the other side, in contact with the porous mineral material cooled by the evaporation of the water on its surface.According to this example, a portion of the cooled airflow exiting the primary channels is directed to the secondary channels where this portion of the airflow is humidified and heated. The humid, heated airflow is then extracted from the secondary channels of the heat exchanger by a fan that draws a portion of air from the room, forming a mixed airflow comprising the humid airflow exiting the secondary channels and an airflow extracted from the room, and directing this mixed airflow to the condensation module.
[0069] One advantage is to allow the primary airflow to be cooled by indirect adiabatic thermal cooling through the walls of the secondary channels entering the primary channels, while also allowing the condensed water from the humid airflow circulating in the condensation module to be recycled by reintegrating it into a water circuit, for example the primary water circuit of the air conditioning system.
[0070] According to one embodiment, the device includes a second fan configured to extract a portion of air from the room to be air-conditioned, said portion of air being mixed with said humid airflow exiting the heat exchanger to form a mixed airflow, said mixed airflow being guided to an air inlet of the condensation module.
[0071] According to one aspect, the invention relates to an indirect adiabatic cooling heat exchanger for integration into a duct. The heat exchanger comprises: at least one primary channel, capable of guiding a primary airflow from an inlet to an outlet; a plurality of secondary channels, thermally connected to said primary channel; and at least one heat exchange element configured to be irrigated by a liquid and to cause, by evaporation, cooling of said secondary channels and, by heat transfer, cooling of said primary airflow.

[0072] According to another aspect, the invention relates to an air treatment assembly, comprising an existing duct of a building and a heat exchanger such as indirect adiabatic cooling, said existing duct being a chimney flue, a stove flue, or a controlled mechanical ventilation duct, said heat exchanger being arranged inside said existing duct.
[0073] According to another aspect, the invention relates to an air conditioning device comprising: • an air inlet cooperating with a first fan allowing to extract and direct a primary airflow from a first zone located outside the room towards a heat exchanger;
[0074] • the heat exchanger cooling said primary airflow to generate at least one cooled airflow from a passage of the primary airflow through the heat exchanger, and comprising at least one air outlet to guide at least a portion of said cooled airflow towards at least one air outlet opening onto the room to be air-conditioned;
[0075] • an infrared radiation concentrator concentrating infrared radiation emitted and / or reflected by surfaces of the device towards an infrared concentration zone;
[0076] • an infrared radiation diffuser to direct said infrared radiation concentrated in said concentration zone towards at least one output of the device.

[0078] Other features and advantages of the invention will become apparent from the detailed description that follows, with reference to the attached figures, which illustrate:

[0082] Figure 4: a schematic representation of the first dehumidification module, in an embodiment in which it comprises a second tube arranged circumferentially in a first tube, and a plurality of secondary electrodes arranged in the second tube.
[0083] Description of the invention According to a first aspect, with reference to figure 1, the invention relates to a room air conditioning device 100, also referred to as "the device 100" in the rest of the description.
[0084] More generally, the invention relates to an air treatment device. Indeed, beyond its primary function of cooling an airflow, the device is capable of modifying other physicochemical characteristics of the air. In particular, the device can regulate the humidity level, for example by means of at least one dehumidification module, and also improve air quality through filtration or decontamination. In one embodiment, the device heats the air rather than cooling it.
[0085] Therefore, in the remainder of this description, the term "air conditioning device" is used for the sake of brevity to refer to such an air treatment device. This term should thus be understood in its broadest sense and should not be interpreted as limiting the invention to a simple cooling function. The term "air conditioning" here encompasses any form of air treatment implemented by the device.
[0086] The device includes an air inlet 101 cooperating with a first fan. The first fan extracts and directs a primary airflow FAEI from a first zone located outside the room towards a heat exchanger 110.
[0087] Device 100 includes a heat exchanger 110 cooling the primary airflow FAEI to generate a cooled airflow FAR.
[0088] The term "cooled airflow FAR" refers to an airflow with a temperature lower than the temperature of the primary airflow "FAE" entering the heat exchanger 110.
[0089] The heat exchanger 110 has at least one air outlet to guide at least a portion of the cooled airflow FAR to at least one dehumidification module 120, 130.
[0090] The device 100 includes at least one dehumidification module 120, 130. The dehumidification module 120, 130 is configured to dehumidify the portion of the cooled airflow FAR in the heat exchanger 110, and to generate a treated airflow FAS comprising at least one portion of air resulting from said dehumidification of said portion of the cooled airflow FAR. In some embodiments, the heat exchanger includes at least one primary channel 111 and further includes at least one secondary channel 112.
[0091] According to one embodiment, the cooled airflow FAR exiting the heat exchanger 110 includes a first portion of airflow FARI exiting the heat exchanger 110 through a first air outlet of at least one primary channel 111. In this configuration, the cooled airflow FAR includes a first portion of airflow FARI that has undergone initial cooling without a phase change in the primary channel 111. The first air outlet of the heat exchanger 110 leads, for example, to the second dehumidification module 130.
[0092] In some embodiments, the portion of cooled airflow FAR guided to at least one dehumidification module 120, 130 is humidified and / or heated upstream of its entry into said dehumidification module 120, 130.
[0093] In one example, the cooled airflow FAR comprises an airflow exiting the heat exchanger 110 through an outlet of at least one secondary channel 112. In this configuration, the cooled airflow FAR includes, for example, a second airflow portion FAR2, distinct from the first airflow portion FAR, exiting, for example, from at least one primary channel 111 to be directed to at least one secondary channel 112. In this configuration, the second airflow portion FAR2 is, for example, humidified and heated as it passes through at least one secondary channel 112, and then directed to the first dehumidification module 120, at least partially in the form of water vapor. In this configuration, the first dehumidification module 120 allows, for example, the condensation of a volume of water contained in the humid airflow exiting at least one secondary channel, for example, by corona effect using a plurality of electrodes.This volume of condensed water is, for example, reintegrated into a water circuit of the air conditioning device, and the airflow resulting from the condensation caused in the first dehumidification module 120 is, for example, redirected to the air inlet 102 of the air conditioning device. The device 100 has an air outlet 102. The air outlet 102 directs the treated airflow FAS to a second zone to be cooled located inside the room.
[0094] Device air inlet, first fan for primary airflow extraction F A E
[0095] According to one embodiment, the first fan is powered by an electric generator, enabling the rotation of its blades to extract the primary airflow FAEI from the first zone located outside the room towards the heat exchanger 110.
[0096] According to one embodiment, the diameter of the first fan is between one hundred millimeters and two hundred millimeters. The diameter of the first fan is, for example, approximately one hundred and fifty millimeters.
[0097] One advantage is that it allows the first fan to be positioned in an existing duct that imposes sizing constraints, such as a chimney flue.
[0098] According to one embodiment, the first fan is a mechanically controlled ventilation fan, commonly referred to by the acronym "MCV".
[0099] According to one embodiment, the first fan is configured to deliver an air flow of between five hundred and fifty cubic meters per hour and six hundred and fifty cubic meters per hour, for example about six hundred cubic meters per hour.
[0100] One advantage is ensuring sufficient air supply in the air conditioning unit 100 to allow the room to be cooled.
[0101] According to one embodiment, the power of the first fan is between forty Watts and sixty Watts, for example fifty Watts.
[0102] According to one embodiment, the first fan is configured to generate an A-weighted sound power level of between thirty A-weighted decibels and thirty-five A-weighted decibels, for example thirty-two A-weighted decibels.
[0103] One advantage is limiting the level of noise perceived by the human ear. Another advantage is complying with French thermal, acoustic, and ventilation regulations.
[0104] According to one embodiment, the first fan exerts a suction pressure of about five hundred Pascals.
[0105] Air conditioning unit designed to be integrated into a chimney in a room of a building, such as a dwelling
[0106] The air conditioning device 100 of the invention is particularly suitable for integration into a chimney of a room, for example a chimney of a room in a building, for example a chimney of a Parisian-style apartment, for example a chimney of an apartment in a Haussmann-style building.
[0107] According to one embodiment, the air conditioning unit 100 is sized to be integrated into a chimney of the room to be air-conditioned.
[0108] The term "chimney" refers to an assembly comprising a fireplace and a chimney flue. The fireplace is, for example, located inside the room to be air-conditioned.
[0109] The chimney flue includes, for example, a first inlet and / or outlet opening onto an area outside the premises. The first inlet and / or outlet of the chimney flue is, for example, located on the roof of the premises, or on the roof of a building containing said premises. The chimney flue includes, for example, a second inlet / outlet opening onto the fireplace. The chimney flue includes, for example, walls delimiting a first space allowing the circulation of one or more fluids between the first inlet and / or outlet and the second inlet and / or outlet. The walls of the chimney flue delimit, for example, a circulation space for the primary airflow (FAEI) between its first inlet and / or outlet and its second inlet and / or outlet.The walls of the chimney flue allow, for example, to guide at least one flow of air and / or a flow of water from the first inlet and / or outlet of the chimney flue to the second inlet and / or outlet of said chimney flue, and / or to guide at least one flow of air and / or a flow of water from the second inlet and / or outlet of said chimney flue to the first inlet and / or outlet of said chimney flue.
[0110] The chimney firebox includes, for example, walls delimiting a second space. The second inlet and / or outlet of the chimney flue opens, for example, into the second space delimited by the walls of the chimney firebox. The second space delimited by the walls of the chimney firebox can advantageously accommodate, for example, multiple components of the air conditioning system 100, such as the heat exchanger 110 and / or at least one dehumidification module 120, 130 and / or at least one water tank supplying a water circuit of the air conditioning system and / or at least one primary airflow decontamination element FAE, such as a UV-C lamp.
[0111] A first, non-limiting example of integrating the 100 air conditioning unit into a building's chimney is described below. In this example, the room to be air-conditioned is a room in an apartment of the building, and the fireplace is located in that room.
[0112] According to this example, the first fan is arranged in an upper portion of the first space delimited by the walls of the chimney flue, near the roof of the building.
[0113] One advantage of such a positioning of the first fan is to allow a continuous supply of hot, dry air.
[0114] Another advantage is capturing an airflow in an area far from urban pollution sources.
[0115] Another advantage is capturing an airflow whose humidity remains stable, even during heat waves.
[0116] According to this example, the first fan is a mechanically controlled ventilation fan, commonly referred to by the acronym "MCV".
[0117] The first fan is electrically powered, allowing its blades to rotate and extract the primary airflow (FAE), which in this example is a portion of outside air, from the first zone located at the roof level of the building. This FAE is then directed to the first inlet / outlet of the chimney flue, which includes an air intake. The extracted and directed FAE is then guided through the first space defined by the chimney flue walls to the second inlet / outlet of the same flue, which includes an air outlet.
[0118] Integrating the 100 air treatment device into an existing chimney flue offers particularly significant advantages, as it allows the intrinsic thermal, aerodynamic, hygrometric and optical properties of the latter to be exploited to improve its performance and efficiency.
[0119] From an aerodynamic point of view, the device benefits from the natural draft, or chimney effect, generated by the temperature difference between the base and the top of the duct. This upward airflow assists the operation of the first fan, thus reducing its energy consumption, and allows for the passive removal of residual heat when the device is off, for example, overnight.
[0120] From a thermal perspective, integrating the 100 device into a traditional vertical flue is particularly advantageous. The significant thermal inertia of the flue walls, especially when made of dense materials such as solid brick, stone, or cast iron, acts as a buffer, absorbing the operating heat of the 100 device during periods of use and dissipating it slowly, thus contributing to the system's stability and longevity.
[0121] Furthermore, this high thermal inertia, combined with low exposure to direct solar radiation during the summer, keeps the duct walls at a temperature lower than that of the outside ambient air. This temperature difference is advantageously used to passively pre-cool the primary airflow as it descends through the duct, upstream of its entry into the heat exchanger 110. This pre-cooling step smooths out temperature variations in the incoming airflow, reduces its initial heat load, and consequently decreases the energy demand on device 100 to reach the setpoint temperature, thus improving its overall efficiency. Moreover, the temperature gradient maintained along the vertical duct, particularly during nighttime or transitional seasons, enhances the natural thermal draft effect.
[0122] This phenomenon promotes passive air circulation, reducing the need for mechanical ventilation and also contributing to the overall energy efficiency.
[0123] From a hygrometric perspective, the use of a chimney flue also offers significant advantages. These flues are generally dry environments, isolated from ground moisture and inclement weather. This dryness of the internal walls promotes partial drying of the primary airflow as it travels through the flue. This phenomenon, resulting from the adsorption of moisture by the flue materials and the establishment of a hygroscopic equilibrium, is particularly beneficial to the efficiency of the system.
[0124] Indeed, the drier the primary airflow is upon entering the heat exchanger 110, the higher its evaporative potential. This condition directly optimizes the efficiency of the indirect adiabatic cooling process implemented in the heat exchanger, maximizing heat transfer through evaporation and thus improving the overall cooling performance of the device 100.
[0125] Finally, the optical properties of the duct are also exploited. The internal walls, particularly in older urban environments, are often coated with blackened combustion residues such as soot composed of carbon nanoparticles. This layer exhibits high emissivity, especially in the infrared spectrum. It thus acts as a large-surface passive radiator, efficiently capturing the heat radiated by the surfaces of the air handling unit and transferring it to the upward airflow. This synergy transforms a simple duct into an active component of the heat dissipation system.
[0126] Monoblock configuration and complete integration
[0127] According to a particularly advantageous embodiment, the air conditioning device 100 is configured to form a monobloc unit fully arranged inside a duct, such as a chimney flue.
[0128] The term "fully assembled" means that all the functional components of the device 100 - in particular the heat exchanger 110, and / or the dehumidification modules 120, 130, the first fan, and the primary water circuit 140 - are contained within the internal volume delimited by the walls of said conduit.
[0129] In this configuration, the device 100 does not include any remote functional unit located outside the building. More specifically, the device lacks any external heat exchanger that would be connected, for example, by refrigerant or heat transfer fluid lines, to components located inside the chimney flue. The invention thus eliminates the need to establish a fluid connection through the walls of the room or building between an indoor unit and an outdoor unit.
[0130] A primary advantage of such a monobloc configuration is that it allows for a completely non-intrusive installation, which requires no drilling of the exterior walls and preserves the aesthetic and structural integrity of the building's facade.
[0131] Another advantage lies in the compactness and optimized architecture that such integration requires. Grouping all the components into a single unit housed within the duct allows for synergistic thermal management, for example by exploiting the natural draft of the duct to assist heat dissipation, thus improving the overall energy efficiency of the system.
[0132] This embodiment is therefore fundamentally different from hybrid systems in which an external heat exchanger would be coupled to an air handling unit arranged in a chimney, such systems requiring complex interconnection and an installation comprising both internal and external elements.
[0133] Integration into various types of conduits
[0134] In other embodiments, the 100 air conditioning unit can be integrated into various types of existing ducts within a building, such as a service duct or an existing building duct, its application not being limited to a chimney. This versatility is a major advantage, particularly for installation in buildings where installing a conventional air conditioning system would be complex or intrusive.
[0135] In a particular embodiment, device 100 is arranged within a controlled mechanical ventilation (CMV) duct. In the case of a single-flow CMV system, the existing exhaust duct can be used to direct the primary airflow (FAE) from an outside area to the air inlet 101 of the device. In the case of a dual-flow CMV system, device 100 can advantageously be integrated in parallel with, or as a replacement for, the existing heat exchanger, thus enabling synergy with the building's overall ventilation system to improve energy efficiency and air quality.

[0137] The invention is particularly advantageous for integration into concentric ducts, such as those used for condensing boilers. In such a configuration, the boiler's peripheral combustion air supply duct can serve as the first zone for the extraction of the primary airflow (FAE), while the central flue gas exhaust duct can be used for heat dissipation from the air conditioning unit 100, thus making optimal use of the existing infrastructure.
[0138] More generally, the invention extends to the integration of the device 100 into any duct, whether vertical or horizontal, ensuring fluid communication between an interior and exterior zone of the room.

[0149] In this example, the second dehumidification module 130 includes a moisture-capturing material, for example sodium chloride, or lithium chloride, enabling the capture of moisture present in the first portion of the cooled FARI airflow exiting the primary channels 111.
[0150] In this example, at least one air outlet of the second dehumidification module 130 leads to the air outlet 102 of the air conditioning unit 100.
[0151] In this example, a treated airflow FAS from the cooling and dehumidification of the primary airflow FAE is directed from the air outlet 102 of the device 100 to the room to be cooled in the apartment of the building.

[0326] Standalone module configuration
[0327] In another embodiment, the air handling unit 100 can be configured as a self-contained module, not requiring integration into a pre-existing building duct. In this configuration, the unit 100 is housed in its own enclosure or casing and is connected to a dedicated duct system to ensure air exchange between the second zone to be cooled, located inside the room, and the first zone, located outside the room.
[0328] Such a configuration is particularly suitable for air conditioning or air treatment of isolated spaces or spaces without integrated ducts, such as converted shipping containers, construction site bungalows, temporary shelters, or even technical rooms or cellars.
[0329] The installation then consists of making at least one opening in a wall of the room, for example a wall, a floor or a ceiling, to allow the passage of the dedicated ducts connecting the air inlet 101 and the air outlet 102 of the device 100 respectively to the outside zone and the inside zone.
[0330] One advantage of this design is that it offers a highly flexible air treatment solution that can be rapidly deployed in modular or temporary structures. Although it requires an opening in the wall, installation remains considerably simpler compared to a split-type air conditioning system, as the 100 unit is a single-unit system that does not require a complex refrigerant circuit between an indoor and an outdoor unit.
[0331] In this embodiment, the device 100 retains its internal architecture and all of its functional components, including the heat exchanger 110 and the dehumidification modules 120 and 130, to ensure complete and effective air treatment. According to another embodiment, the air treatment device 100 is configured to operate as a self-contained unit with complete recirculation within the room to be treated.
[0332] In this configuration, the device requires no fluid connection or duct to an external area. The air inlet 101 is designed to draw in ambient air directly from the room. This air then passes through the device's functional modules, where it is treated. The treated air is finally discharged back into the same room through the air outlet 102, thus creating a closed-loop treatment cycle.
[0333] This operating mode is particularly advantageous for applications where a fixed installation is impossible or undesirable. It is suitable for air treatment in enclosed spaces such as containers, meeting rooms, archives, or any room without easy access to the outside.
[0334] The device 100 retains its internal architecture and its ability to cool and dehumidify the circulating airflow. Cooling is provided by the heat exchanger 110, and the humidity extracted from the airflow, including that generated by the internal evaporation process, is captured and managed by the dehumidification module(s) 120, 130.
[0335] The main advantage of this configuration lies in its complete autonomy and mobility. The device can be positioned and operated in a room without requiring any installation or structural modifications, offering an immediately operational air treatment, cooling, and dehumidification solution.
[0336] Modularity and functional autonomy of components
[0337] It should be noted that the architecture of the air treatment device 100 is modular in nature, with each main component capable of functioning as a self-contained technical entity.
[0338] Thus, the heat exchanger 110 can be considered as an independent cooling module, capable of implementing indirect adiabatic cooling of an airflow without requiring the presence of dehumidification modules.
[0339] Similarly, the first 120 dehumidification module constitutes an autonomous active dehumidification unit, capable of extracting a volume of water by condensation from a humid airflow, regardless of the source of that flow.
[0340] Finally, the second dehumidification module 130 forms a self-contained passive dehumidification unit, capable of capturing moisture from an airflow by means of an absorbent material, and can be used in any application requiring hygrometric control.
[0341] Each of these modules thus represents a unique invention, which can be implemented alone or in other combinations. The description of device 100 illustrates an example of the synergistic integration of these modules, but does not limit their individual applications.
[0342] Experimental validity of performance
[0343] Experimental tests were conducted to validate the thermal performance of device 100 in an integrated configuration. In one implementation example, device 100 was arranged inside a chimney flue and put into operation under summer conditions.
[0344] In a representative test, the primary airflow temperature measured at the device inlet was 31°C. After a warm-up period of approximately twenty minutes, the treated airflow temperature measured at the device outlet 100 stabilized at 19°C. An average treated airflow rate of approximately 600 m³ / s was also observed. 3 / h during this period.
[0345] This result demonstrates a temperature drop of 12°C between the incoming and treated air. Furthermore, it was observed that this outlet temperature of 19°C was maintained stably and continuously for the entire remaining duration of the test, i.e., for one hour and thirty minutes, thus confirming the device's ability to provide significant and constant cooling under normal operating conditions.
