AIR TREATMENT DEVICE

TECHNICAL FIELD

The present invention relates to an air treatment device. In particular, the air treatment device according to the present invention allows intensive sanitization of the air passing through an aeration duct and subsequently introduced into an internal environment of a building. In addition ? object of the present invention is an air treatment module and an air treatment system comprising the aforementioned air treatment device.

STATE OF THE ART

Nowadays ? It has become essential to ensure that internal environments, i.e. indoor environments, of civil, commercial or industrial buildings, meet high standards of hygiene to protect the health of people who find themselves spending longer periods of time within these environments. or less limited and ensure the successful completion of the activities? carried out within these environments. The need to achieve and maintain high hygiene standards is even more pressing. marked in the interior environments of buildings which are generally crowded or which are, at least, intended to accommodate a large number of people.

Indeed, it is known that poor air sanitation in indoor environments where many people are in close contact favors the transmission of diseases, even epidemically.

Often the air present in the internal environments of a building, especially when it is recirculated more times, i.e. when there are difficulties? replacement of the same, it is more? polluted or contaminated air outside the building. Can volatile pollutants of a heterogeneous nature stagnate and proliferate in the air within internal environments? including fibrous particles, fine dust, microorganisms in the form of spores, moulds, viruses and bacteria. The polluting agents can remain suspended in the air or deposited on surfaces, such as for example the surfaces of furniture or machinery, present within the internal environment and therefore easily and quickly come into contact with the people who frequent this environment .

In order to reduce the presence and propagation of pollutants within the internal environments of buildings, the sanitization of the air introduced into these environments plays a role of primary importance.

In the context of the prior art, various types of air treatment devices have therefore been developed. Such air handling devices can be operated individually, for example portable devices, or can be configured to be coupled to a building ventilation system.

In particular, some of the air treatment devices of the known art comprise units operatives configured to be associated with an aeration duct so as to interfere with the flow of air passing through said duct and to diffuse a sanitizing agent into said air flow. By sanitizing agent we mean a substance capable of neutralizing or breaking down the pollutants typically present in the air of the internal environments of buildings. Through the dissemination of such a sanitizing agent ? therefore it is possible to reduce the presence of polluting agents in the same air within the internal environment. Furthermore, the treated air, i.e. the air in which it is widespread the? sanitizing agent can? touch and sanitize areas and surfaces within the internal environment that are difficult to access by an operator during normal cleaning operations.

Obviously major ? the concentration of the sanitizing agent that is introduced into the higher air? the effectiveness of the sanitization of the latter.

However, in order to ensure sufficient sanitization of the air, ? It is necessary to reach concentration levels of the sanitizing agent in the air which, for some types of sanitizing agents, could be irritating or even harmful to the people immersed in them. For example, a widely used sanitizing agent ? the ozone. Ozone has an oxidizing power, from which derives its bactericidal, fungicidal and virus inactivating effect. For this, the ozone ? widely used as a sanitizing agent, also in the environmental field. However, to obtain a sanitizing effect, ? It is necessary that the concentration of ozone present in the air reaches levels with respect to which human exposure is unacceptable. considered healthy, therefore the sanitization action by diffusion of ozone in the environments to be sanitized must be carried out at different times in time from when such environments can foresee the presence of people inside them.

A traditional air treatment device ? equipped with a frame that can be fixed to an air distribution duct so that the device, following its installation, protrudes inside the duct to be hit by a flow of air.

This known solution has the significant drawback of causing an annoying noise level. due to the aerodynamic interference of the device with the flow of air that invests it.

This defect causes significant noise pollution when there are people in the room served by the system incorporating it.

SUMMARY

The problem at the basis of the present invention ? that of eliminating the problems outlined with reference to the prior art cited above, providing an air treatment device capable of diffusing a quantity of a sanitizing agent sufficient to carry out a deep sanitization of the air to be introduced into the internal environment of a building and to guarantee, at the same time, respect for the health of the people who find themselves frequenting the environment in which the sanitized air is introduced.

Another object of the present invention ? that of making an air treatment device available which allows for the reduction or avoidance of noise pollution in the internal environment served by the air treatment system in which the device? installed or incorporated.

This task, as well as these and other objects which will become apparent hereinafter are achieved by an air treatment device according to the attached claim 1, an air treatment module according to the attached claim 12 and an air treatment system according to the attached claim 13.

Detailed characteristics of the air treatment device, of the air treatment module and of the air treatment system according to the invention are set forth in the dependent claims.

DETAILED DESCRIPTION

With particular reference to the figures cited, ? The reference number 10 generally indicates an air treatment device according to the present invention.

The air treatment device 10 according to the present invention is suitable for use for the sanitization of the air circulating inside the ventilation ducts of systems used for the transport and/or treatment of air, such as for example ventilation systems, of air conditioning, heating, and intended to be introduced into the AI internal environment of a building.

With the term ?sanitization? in the context of this text, generically means the set of purification or sterilization operations of the air, aimed at neutralizing or reducing pollutants, even of different nature, present in it and especially, but not limited to bacterial or viral.

The air treatment device 10 can? be configured to be coupled to an aeration duct 20. The aeration duct 20 can? comprising a tubular body 210 which internally defines an air passage channel 211. This air passage channel 211 can be capable of being traversed or traversed by a flow of air. The tubular body 210 can? have a substantially cylindrical, truncated cone or parallelepiped shape. The tubular body 210 can? be provided with a through opening 212 for accessing the air passage channel 211.

The air treatment device 10 according to the present invention can comprise a support 110 which includes a fixed part 111, which can be fixed to the tubular body 210, and a movable part 112. The support 110 can? be equipped with a fixed part 111, configured to be stably associated with the tubular body 210, and with a mobile part 112, which can be configured to be mobile with respect to the fixed part 111 and, consequently, with respect to the tubular body 210.

The air treatment device 10 according to the present invention also comprises a unit operating unit 120 suitable for diffusing a sanitizing or sterilizing agent in the air and fixed to the movable part 112 of the support 110. Since the unit? operative part 120 stably associated with the mobile part 112 is it? destined to move together with the latter. Preferably, the unit? operational 120 pu? include or consist of an ozone generator, per se? traditional. For example, this ozone generator can? be of the type with corona discharge (Corona Discharge - CD), of the cold plasma type or with at least one lamp capable of emitting ultraviolet radiation, in particular UV-C.

The air treatment device 10 can? understand more unit? operational 120 fixed to the movable part 112 of the support 110. The number of units? operational 120 pu? be chosen by an expert technician in the field according, in particular, to the size of the pipeline and its flow rate.

The air treatment device 10 can? comprising actuation means 130 connected to the fixed part 111 and to the mobile part 112 which can be activated to operate an automatic movement of the mobile part 112 with respect to the fixed part 111 between an operative configuration and a rest configuration. In other words, the actuation means 130 can be configured to give the movable part 112 an automatic movement between the operative configuration and the rest configuration. Preferably, the actuation means 130 can comprise an actuator; for example an electric actuator. Furthermore, the actuation means 130 can preferably comprise an electric motor possibly equipped with a speed reducer.

The automatic movement? such that, when the fixed part 111 ? fixed to the tubular body 210:

- in the operational configuration, the unit? operational 120 ? at least partially inserted into the air passage channel 211 to intercept an air flow, e

- in the rest configuration, the unit? operational 120 ? extracted with respect to the air passage channel 211.

That is to say, when the fixed part 111 ? connected to the tubular body 210, the automatic movement of the mobile part 112 does s? that the unit? operative part 120, associated with the latter, is or is not positioned, at least partially, within the channel 211 for the passage of the air through the through opening 212 of the tubular body 210. In other words, the movable part 112 can? be moved by the actuation means 130, through the opening 212, in such a position that the unit? operating unit 120 occupies at least a part of the air passage channel 211, to be lapped by the air which, in operation, travels through the channel 211. In this way, the unit? operational 120 ? placed selectively in contact with an air flow to be treated or separated from it. The unit operational 120 ? why? made liable to interfere with the flow of air circulating in the air passage channel 211.

It therefore follows that, advantageously, the unit? operational 120 pu? carry out the sanitization of the flow of air with which it comes into contact inside the channel 211 for the passage of the air selectively, ie when necessary. In this way ? It is possible to use substances, such as ozone for example, as sanitizing agents, which in high concentrations or in the long term could be harmful to the health of people who are or will find, after sanitization, in the AI internal environment.

In fact, when the AI internal environment to be sanitized is not? engaged by people, the unit? operational 120 pu? be automatically brought into the operative configuration and activated to treat the air flow which runs through the air passage channel 211 directed to the room itself.

In this case, since there are no people in the internal AI environment, any noise due to the presence of? unit? operation 120 in channel 211 is irrelevant.

The sanitized air flow, i.e. containing the sanitizing agent, can then be introduced, through the ventilation duct 20 to which the air treatment device 10 is connected. associated or possibly through other ventilation ducts which the latter? connected, within the internal AI environment of a building. Coming into contact with the surfaces within the AI internal environment, the sanitized air flow, thanks to the presence of the sanitizing agent, allows the pollutants present, for example, on machinery or furnishings to be neutralised.

In addition, the sanitized air flow, circulating within the ventilation duct 20, also contributes to sanitizing the internal surfaces of the ventilation duct 20 itself.

Instead, when the internal environment AI ? engaged by people, the unit? operational 120 pu? be deactivated and placed in the rest configuration, so it can? be external to the air passage channel 211 or in any case arranged in such a way as not to significantly interfere with the air flow which passes through it, to avoid generating noise.

So, the unit? operational 120 not being permanently inserted, within the channel 211 for the passage of the air also involves a minimal impact on the aerodynamic performance and operating characteristics of the aeration duct 20. This? ? particularly advantageous since it makes it possible to associate the air treatment device 10 according to the present invention also with an aeration duct 20 of a pre-existing system without altering its performance, for example in terms of noise, load losses, distribution of? air, speed? residual air flow at a fixed height with respect to the floor, compared to what was established in the project.

Furthermore, since the unit? operational 120 ? positioned within the air passage channel 211 only when needed, it ? subject to reduced wear due to exposure, i.e. direct contact, with the air flow. Does this result in an increase in the useful life of the unit? operational 120.

A further advantage consists in the fact that, if maintenance interventions have to be carried out on the unit? operative 120, this can be found outside the tubular body 20. ? therefore facilitated the access to the unit? operational 120 by a maintenance worker.

In the operational configuration, the moving part 112 can? be configured to have the unit? operative 120 within the air passage channel 211 so that the air flow circulating within the latter crosses or skirts the same unit? operative 120. Advantageously, in this way, the unit? operational 120 pu? optimally diffusing the sanitizing agent within the air flow passing through the air passage channel 212.

Clearly, the sanitizing agent can? be an agent extraneous to the air flow or obtained by a treatment of the latter, as mentioned above with reference to ozone.

According to a preferred aspect of the present invention , the air treatment device 10 can also including a? unit? of control 140 connected to the drive means 130 and/or to the unit? operational 120. The connection between the? unit? of control 140 and the actuation means 130 and/or to the unit? operational 120 pu? be wired or wireless. This unit? control 140 pu? be configured and/or programmed to control the drive respectively of the drive means 130 and/or of the unit? operative 120. Preferably, the unit? of control 140 ? configured or programmed to operate the? unit? operative 120 only when the movable part 112 is in the operative configuration. That is to say that the unit? operational 120 ? operated only when it ? located, at least in part, within the air passage channel 211.

In particular, the unit? control 140 pu? be configured and/or programmed to activate the drive means 130 and the unit? operational 120 in particular predefined time slots. For example, the unit? control 140 pu? be configured and/or programmed to activate the drive means 130 and the unit? operational 120 during the night or at other times when the internal AI environment does not host people.

According to a preferred aspect of the present invention , the air treatment device 10 can further comprising a detection means 150 suitable for detecting the concentration of the sanitizing agent, such as for example an ozone detector. The means of detection 150 pu? be configured to detect the sanitization agent concentration within the AI indoor environment. In this sense, the detection means 150 can be configured to be placed in the internal AI environment itself.

Additionally, or alternatively, the air treatment device 10 can comprise a presence detection device 160, which can, for example, comprise at least one movement sensor, configured to detect the presence of people in the internal environment AI and, on site, positioned in or facing it.

The unit control 140 pu? be connected to the sanitizing agent concentration detection means 150 and/or to the presence detection device 160 and can? be configured and/or programmed to control the drive, ie the activation, of the drive means 130 and/or of the unit? operational 120 according to the data detected respectively by the detection means 150 of the concentration of sanitizing agent and/or by the presence detection device 160.

For example, the unit? control 140 pu? be configured and/or programmed to inhibit or stop the operation of the mobile part 112 and/or the unit? operative 120 if the sanitizing agent concentration detected by the sanitizing agent concentration detection means 150 does not satisfy a first predefined condition. This first predefined condition pu? be satisfied if the sanitizing agent concentration detected by the sanitizing agent concentration detecting means 150 ? less than a predefined maximum threshold.

For example, the unit? control 140 pu? be configured and/or programmed to inhibit or stop the operation of the mobile part 112 and/or the unit? operative 120 if a second predefined condition is not satisfied. This second predefined condition pu? be satisfied if the presence detection device 160 does not detect the presence of people for a time shorter than a predefined minimum interval.

The unit control 140 pu? include for example a PLC or other type of electronic controller. In addition, the unit? control 140 pu? include a display screen 141 equipped with a keyboard 142 to allow, for example, a user: display of the operating status of the air treatment device 10, the possibility? to carry out an emergency stop of the air treatment device 10, the possibility? to program or set the values to be attributed to the predefined maximum threshold or to the predefined minimum interval.

The 110 support can? delimiting a niche 113, i.e. a hollow space. In particular, according to this same preferred aspect, in the rest configuration the unit? operational 120 ? portrayed within the niche 113 while in the operative configuration the unit? operative 120 protrudes from the niche 113. This niche 113 ? therefore intended to accommodate the? unit? operative 120 when the mobile part 112 is in the rest configuration, ie when the unit? operative 120 is located outside the tubular body 20. The support 110 can therefore? be configured to define a shelter or a cover for the unit? operative 120 when the latter does not ? in use within the air passage channel 211. Advantageously, ? preserved l? integrity? of? unit? operative 120 also in the rest configuration of the mobile part 112.

The niche 113 can? be configured in such a way as to delimit inside it an open space on the air passage channel 211 but closed towards the outside of the tubular body 20 when the fixed part 111 is? coupled to the latter.

According to a preferred aspect of the present invention , furthermore the support 110 can be provided with a compartment 117, or compartment, configured to house the drive means 130. Preferably, furthermore, the compartment 117 is watertight, ie watertight, so as to preserve the actuation means 130 from humidity, dirt and from contact with the sanitizing agent.

The air treatment device 10 can? be configured in such a way as to prevent the leakage of air from the channel 211 through itself? when support 110 ? fixed to the tubular body 20. In particular, the mobile part 112 can be configured in such a way that when it is in the rest configuration, the niche 113 and the air passage channel 211 are physically separated from each other. ?, that is, a fluid communication is prevented between the niche 113 and the air passage channel 211 when the movable part 112 occupies the rest configuration. It follows that, advantageously, when the movable part 112 is in the rest configuration, there are no turbulences or load losses due to the leakage of air from the air passage channel 211, through the opening 212, towards the niche 113 In addition, in this way, the unit? operational 120 ? even more preserved from wear or dirt caused by contact with the air flow.

According to a preferred aspect of the present invention, the movable part 112 can comprise or consist of at least one closing wall 118 configured to close the through opening 212 of the tubular body 210 when said movable part 112 is in the rest configuration. That is to say that this closing wall acts as a closing element for the opening 212 of the tubular body 210. In particular, the closing wall 118 can be configured in such a way as to form a positive fit with the through opening 212. In this way, in the rest configuration of the movable part 112, the closing wall 118 is flush with the perimeter edges of the through opening 212.

Such at least one closing wall 118 can? be connected to the fixed part 111 and configured to be connected to the tubular body 20 near? or correspondence of the perimetric edges of the through opening 212. In particular, the support 110 pu? furthermore comprise elastic means configured to maintain the at least one wall 118 in a position such as to close the through opening 212 of the tubular body 20 when the unit? operational 120 ? extracted with respect to the air passage channel 211. Alternatively, the support 110 can instead comprise a kinematic mechanism configured to guide the at least one closing wall 118 between a closed position, in which it obstructs or closes the through opening 211, and an open position, in which it leaves free the? through opening 212 for the insertion of the? unit? operative 120 within the air passage channel 211.

According to a preferred aspect of the present invention , the support 110 can comprise or consist of a box-like body 116 having a plurality? of walls. The plurality? of walls delimits the niche 113 within which the unit? operational 120 pu? be welcomed.

Preferably, the at least one closing wall 118 comprises or consists of one or more? walls of plurality of walls of the box-shaped body 116. That is, one or more? walls of the box-like body 116 can/can act as a closing element for the through opening 212. The other walls of the plurality? of walls can form, even partially, the fixed part 111 of the support 110.

In this way, the air treatment device 10 is structurally compact and simple to construct.

According to a further preferred aspect of the present invention , the support 110 can comprise a pin 114 defining an axis of rotation A. In particular, the fixed part 111 and the mobile part 112 can be mutually connected by means of the pin 114 so that the mobile part 112 can be tilted with respect to the fixed part 111 around the axis of rotation A. In other words, the fixed part 111 and the mobile part 112 can be mechanically connected to each other by means of the pin 114 and the mobile part 112 can? be capable of performing a rotation around the axis of rotation A defined by the pin 114. The movable part 112 can? be that? rotatably connected, i.e. rotatably, by means of the pin 114, to the fixed part 111. The automatic movement can? be that? a rotational or tilting movement around the axis of rotation A defined by the pin 114.

According to a further preferred aspect of the present invention , the support 110 can comprise a guide 115 defining a sliding direction B. In particular, the fixed part 111 and the mobile part 112 are mutually connected by means of the guide 115 in such a way that the mobile part 112 is mobile with respect to the fixed part 111 along the sliding direction B. In other words, the fixed part 111 and the mobile part 112 are mechanically connected to each other by means of the guide 115 and the mobile part 112? adapted to perform a translation along the sliding direction B defined by the guide 115. The automatic movement? that is? a translation movement along the sliding direction B defined by the guide 115.

According to a further preferred aspect of the present invention , the support 110 can comprise both a pin 114 defining an axis of rotation A and a guide 115 defining a sliding direction B. In particular, the fixed part 111 and the mobile part 112 can be mutually connected by means of the pin 114 and the guide 115 in such a way that the mobile part 112 is mobile with respect to the fixed part 111 around the rotation axis A and along the sliding direction B. In other words, the fixed part 111 and the mobile part 112 can be mechanically connected to each other by means of the guide 115 and of the pin 114 to perform a roto-translation around the rotation axis A defined by the pin 114 and along the sliding direction B defined by the guide 115.

The guide 115 pu? be stably associated with the fixed part 111 of the support 110 or can? be configured to be permanently associated with the ventilation duct 20. Furthermore, the guide 115 can? be configured to protrude from the fixed part 111 into the air passage channel 211. That is to say that the guide 115 pu? be configured to project through the opening 212 therethrough. The guide can extend for a fixed length along the sliding direction B. Alternatively, the guide 115 can? be telescopic; that is, the length or extension of the guide 115 along the sliding direction B can? be variable. By adjusting the extension of the telescopic guide 115 can? be possible to regulate the? insertion of? unit? operative 120 within the air passage channel 212.

According to a further preferred aspect of the present invention , the air treatment device 10 can understand a? unit? auxiliary operative 121 suitable for diffusing an air sanitizing agent in an air flow from which ? lapped. The unit operational auxiliary 121 pu? be associated with the support 110 in such a way that this is at least partially inserted into the air passage channel 211 to intercept an air flow, when the fixed part 111 is fixed to the tubular body 210. It follows that the unit? auxiliary operative part 121 remains at least partially inserted inside the channel 211 both when the movable part 112 is in the operative configuration and when it is in the rest configuration. In the first case, therefore, that is in the operational configuration, is the unit? operative 120 is the unit? operating auxiliary 121 occupy part of the volume of the air passage channel 211; while in the second case, ie in the rest configuration, only the unit? auxiliary operating 121 occupies part of the volume of the air passage channel 211. In this way, in use, the unit? auxiliary operative continuously sanitizes the flow of air passing through channel 211.

Preferably, the unit? auxiliary operative 121 ? associated with the mobile part 112. Even more? preferably, the unit? auxiliary operative 121 ? associated with the closing wall 118.

Preferably, moreover, the unit? auxiliary operative 121 ? configured to distribute a quantity? of sanitizing agent, per unit? of air, less than the unit? operational 120. In this way ? possible to ensure that the concentration of sanitizing agent present in the air introduced into the indoor environment AI reaches levels with respect to which human exposure is ? considered healthy.

Preferably, the unit? operational auxiliary 121 pu? include or consist of an ozone generator, per se? traditional. For example, this ozone generator can be of the cold plasma type or with at least one lamp capable of emitting ultraviolet radiation, in particular UV-C.

The present invention also relates to an air treatment module 12. The air treatment module 1? according to the present invention can? comprise a section of an aeration duct 20 and an air treatment device 10, as described up to now, coupled to the section of aeration duct 20.

Finally, the present invention also relates to an air treatment system 1 for treating the air entering the internal environment AI of a building. The air treatment system 1 can? consist of or include a ventilation, heating or air conditioning system.

This system 1 can? comprise an air treatment module 12, i.e. an air treatment device 10 associated with a section of an aeration duct 20, and at least one further aeration duct 20. The at least one further aeration duct 20? can? be mechanically coupled to the air treatment module 1?.

According to a preferred aspect, the at least one further ventilation duct 20? ? a microperforated duct or comprises a microperforated duct. The at least one further ventilation duct 20? understand what? a tubular body equipped with a plurality? of through holes. The sanitized air can therefore be spread, through the plurality? of through holes of the at least one further ventilation duct 20? within the internal AI environment. The presence of plurality of holes allows in particular to obtain a homogeneous diffusion of the sanitized air within the AI internal environment. In addition, the sanitized air coming out of the plurality? of holes can? generally assume a speed? such as to induce a turbulent motion in the mass of air already? present in the AI internal environment. In this way ? particularly favored is the mixing or mixing of sanitized air, with a high content of sanitizing agent, with the air present in the AI internal environment.

Finally, according to a preferred aspect, the air treatment system 1 can comprising a ventilation device 11 equipped with an inlet 11a, in fluid communication with an environment external to the building AE, and with an outlet 11b.
