Technical field

The technical solution concerns air-conditioning equipment for sterilization of air, environment and objects by ozone with subsequent automatic regeneration of ozone-depleted air by means of a sensor, filtration and catalytic reaction.

Prior art

The polluted atmosphere greatly affects public health. It causes the sudden onset of diseases such as cancer, asthma, allergies or irritations, rhinitis, COVID, SARS and MERS viruses. As up to 70% of a person's time is spent indoors, in apartments, work, schools, etc., their pollution is a serious threat to human health. The human immune system defends itself when it encounters these harmful elements and produces an excessive amount of white blood cells, which depletes his body and his health is at risk. Fatigue, allergies and illness are most often the cause of an overloaded immune system. Air pollution in enclosed spaces with large, small and gaseous particles.

Large particles are transferred, especially on clothing, shoes or are inflated through doors or windows, possibly from the decomposition of building materials, carpets, clothes and sewn materials. They are also a by-product of humans, animals and plants (dropping of particles of dead skin, hair, pollen, etc.). They are also found in the indoor environment created by human activity, such as vacuuming, cutting, grinding, cooking (flour - baking ...), or powdering, etc. Small particles are carried and blown in the form of smoke, pollen, bacteria, viruses, spores, fungi and the like. They are also formed by smoking, cooking, burning in a fireplace and fireplaces, candles, etc.

Gas particles are found in the air in the form of molecules (formaldehyde, odors, benzenes, phthalates ...), which are carried by the flow of people, changes in temperature or pressure. They are formed by the release of materials and human activity.

Filtration devices are commonly known which, while using a filter cloth, can filter out coarse impurities but cannot filter out live pathogens, very small mechanical particles and gaseous contaminants.

Other commonly known devices are those which, by means of an electrostatic effect, can filter fine and coarse particles but cannot filter gases, while producing ozone harmful to human health, which remains in the target area and are therefore used mainly on average to filter airflow from rooms in which workers are staying in protective masks.

There are also known devices which, with the use of ozonizers, i. j. generator of ultraviolet radiation and / or plasma electric ozone discharge, eliminate a wide range of live pathogens (bacteria such as Salmonella, E. coli, Clostridium, Cryptosporidium, cysts, HIV virus, Herpes virus, jaundice type A, rotavirus and many other microorganisms , viruses, fungi, fungi, mites, insects, rodents and toxic substances contained in building materials) and also eliminate odors in the air and from the surfaces of various objects, as ozone also removes vapors of organic substances such as thinners, gasoline, paints, inks, oils , natural and synthetic, cigarette smell, etc. Unlike complex chemicals, ozone is biodegradable to pure oxygen, so it does not leave toxic waste and does not contaminate the environment, but has no effect on other large, small particles in the air. However, ozone is dangerous at a certain concentration, so it is necessary to ventilate the area for a long time after ozone application. Such devices are placed on an elevated site, the ozonation duration is set and the room is left. Then ozone disinfection takes place. At the end of its set time, the device switches off. However, due to the lack of ozone sensors, it is not clear when the ozone concentration is safe to enter the room, therefore it is recommended to enter usually after 6 - 24 hours in protective equipment (masks), while the residual ozone from disinfection must be thoroughly ventilated.

Various devices described below are also known which combine several of the aforementioned methods.

A technical solution according to DE19902825 is known, which relates to an ozone decomposition reactor (03) consisting of e.g. in photocopiers, ultraviolet sterilizers and similar electrical equipment. The solution is also intended for the removal of O 3 from room air (e.g. from 03 disinfected pools), by introduction into air conditioning and ventilation systems of manganese dioxide (MnO 2)) and / or lead oxide (PbO 2), and / or a similar catalyst suitable for catalytic conversion. 03 to ky slík (02). The disadvantage of the technical solution is that it does not allow cleaning of mechanical impurities and entry into the densified room without a protective mask.

According to the patent KR200399653, a sterilizer for air purification, resp. air flowing through this sterilizer to the outside environment through a photocatalytic filter and an ultraviolet lamp for sterilization and to remove odor. In the absence of ozone, the sterilizer sterilizes and cleans the air, or air e.g. in a motor vehicle, while being able to sterilize bacteria adhered to Steri ozone objects

The K149-2020 U1 lysator consists of an ozone generating module with a safety device located on one side of the air outlet; an anion generating module located on the other side thereof and an operating button unit electrically connecting the ozone generating module and the ozone sensor. It contains a high-capacity battery that is portable, for example in a vehicle, and a motor-driven fan. The disadvantage of this technical solution is its structural complexity and that after the set ozonation time (due to missing ozone sensors) it is not clear when the ozone concentration is safe for human entry, therefore it is recommended to enter it usually after more than 6 hours or in protective equipment, the residual ozone from the disinfection must then be thoroughly ventilated.

According to US2005207951, a device for ozone efficiently deodorizing or sterilizing a space contaminated with a virus, bacteria, fungi and the like above a reference value without adversely affecting the human body is known. The present invention includes an ozone generating unit subjected to ON / OFF control, a control unit for controlling a plurality of safety devices that affect the effective control of ozone concentration in the target area, an air filter function unit having air purification and residual ozone removal function, and a circulation fan. air in the target area. According to the present invention, viruses, bacteria and fungi floating in the air can be removed more efficiently than with a conventional air purifier even with the removal of odors. The disadvantage of such a technical solution is its structural complexity.

Furthermore, according to JP2013188447, sterilization is known in conventional factories of food or similar products using organic acids in the operation. During such long-term operation, resistant bacteria or similar substances appear, as well as dust and bacteria in the atmosphere deposited on the air filter, circulating the air in the room, whereby such bacteria grow and lead to secondary contamination. An air filter for solid dust particles is built into the sterilizer, which also has a sterilizing effect. Dust and bacteria from the atmosphere settle on its air filter. The settled bacteria are further sterilized by the sterilizing effect of an air filter. The clean air passed through the air filter is mixed with ozone and sprayed by rotating the discharge opening 360 degrees to sterilize the airborne bacteria and adhesive bacteria. The disadvantage of this technical solution is its technical complexity and that it requires a continuous small circulation of air, which makes it suitable only for purified air with little contamination of bacteria.

The common disadvantage of all these technical solutions is that they do not allow the removal of coarse, fine particles and at the same time remove viruses, bacteria and spores from the air and surfaces of materials without the need for ventilation and human intervention in protective masks.

From the utility model CZ 34 173 U1, an ozone sterilizer with air regeneration is known, which has a fan mounted in an airtight enclosure, electrically connected to the operating control unit by a supply connected to a power supply and a display member. Below the fan suction, at least one ultraviolet emitter is located in the cabinet above the electrostatic precipitator and below the electrostatic precipitator a dust filter behind at least one of the suction inlets. In the discharge part of the fan, a catalytic filter is placed in the cabinet behind at least one exhaust outlet, sensor and gas filter, in which a switching damper with actuator is fitted, the sensor being electrically separately connected to the fan, electrostatic filter, ultraviolet radiator and actuator via operating control unit. . Such a device is technically complex, has large dimensions and serves for relatively expensive and technically complex efficient multi-purpose large-scale ozone sterilization with subsequent regeneration of air containing also gaseous harmful particles.

Examples of embodiments

In the basic embodiment, the technical solution shown in FIG. 1 to 5. The ozone sterilizer with subsequent air regeneration in the basic embodiment shown consists of a box 1 equipped with four swivel castors 2, a fan 3 with a lower suction and a home outlet, a suction inlet 4 and an exhaust outlet 10 terminated by an unmarked commonly used wall grille. catalytic filters 5, e.g. formed from a catalyst based on MnO 2 + CuO in a frame braid, a dust filter 14, formed e.g. filter cloth G4 according to EN779 mounted in the frame, etc., ozonizer 13, t. j. ozone generator (03), e.g. in the form of a plasma and / or ultraviolet emitter, e.g. consisting of a product of the UV-FAN type series, a switching flap 11 with an actuator 7, a combined sensor 10 of temperature, humidity, CO2 content and ozone content of the treated air, display member 9, operating control unit 8 with a supply 12 connected to a power supply, preferably e.g. . to a standard 230 V / 50 Hz AC mains supply.

In the cabinet 1, a fan 3 is mounted behind the suction inlet 4, above which a switching flap 11 with a servo drive 7 is mounted, behind which an ozonator 13 is mounted under the outlet 6 of the cabinet 1. At the same time next to the switch 11 there is an outlet 6 of the cabinet 1 behind the dust filter. 14 a pair of catalytic filters 5 is mounted at an acute angle to each other, a sensor 10 and an operating control unit 8 with a display member 9 are located on opposite walls of the housing 1, which is separately electrically connected to a fan 3, actuator 7, display member 9, sensor 10 and ozonator 13. .

In the initial position on the wheels, the device is transported to the target cleaned outdoor space, e.g. into a room that needs to be disinfected. It is then checked whether the space is free of persons, animals, plants and according to FIG. 4 and FIG. 5, the ozone sterilizer with subsequent air regeneration is activated by a command from the operational control unit 8 after its connection to the power supply 12 and mechanical setting by operating the operating time, either directly or via a non-displayed start timer to its manually set time or automatic air cleaning cycle. ozonizer 13 controlled after starting the device by control signals from the combined sensor 10, t. j. for as long as it detects that there is some indication in the external digital clean environment of the ozone sterilizer with air regeneration, e.g. the temperature, humidity, CO2 content and ozone content are outside the set reference safe concentration. Subsequently, the target cleaned outdoor space is locked during cleaning.

During cleaning, the operating control unit 8 simultaneously activates the fan 3 and the ozonizer 13 from an initial position via the actuator 7 by means of an electric command (current), the actuator 7 opening the switching flap 11 - see FIG. 1 and FIG. 4. The purification of polluted air in the target cleaned outdoor space takes place by its suction by the fan 3 through the ventilation suction inlet 4 and the ozonizer 13, where ozone

With K149-2020 U1, viruses, bacteria and spores are eliminated via drainage 6 into the target cleaned exterior. During such a cleaning cycle, the sensor 10 reads the values of temperature, humidity, CO2 content and ozone content in the air. The measured values are displayed by the display element 9 and evaluated with their reference value set by the control program in the form of a recommendation for the operator. At the end of the set odorization time or after reaching this ozone reference value in the target cleaned outdoor area, the sensor 10 in the operational control unit 8 switches off the ozonator 13 with an electric command (current) with the fan running 3 and in both cases the actuator 7 is activated, which closes the switch flap 11 - see fig. 1 and FIG. 3, wherein the actuator 11 changes the air path in the ozone sterilizer for subsequent air regeneration. Then the intake air with a high ozone content continues from the intake inlet 4 through the dust filter 14 and the exhaust outlet 6 in the form of oxygen to the target cleaned outdoor space for the time of reaching a suitable health safe oxygen concentration in the target cleaned outdoor space. After reaching this value, the sensor 10 in the operational control unit 8 activates by an electric command (current) the actuator 7, which opens the switching flap 11 - see fig. 1 and FIG. 4, the operation of the fan 3 stops and the operating control unit 8 displays this fact visually and / or also acoustically to the operator in the display member 9, whereby the device is ready in the initial position in the target cleaned outdoor space.

Another embodiment of the subject of the technical solution is alternatively shown in FIG. 6, which in addition to the previously described exemplary embodiment has an operational control unit 8 connected by a router 15 to a wireless remote control 16 for remote control of the device by infrared radiation or radio signals. In the initial position on the wheels, the device is transported to the target cleaned outdoor space, e.g. into a room that needs to be disinfected. After it is checked whether the space is free of people, animals and plants, the target cleaned outdoor space is locked during its cleaning and the wireless remote control 16 starts its operating control unit 8 through the router 15, which simultaneously activates by electric command (current) from the starting position via the actuator. 7, the fan 3 and the ozonizer 13, the actuator 7 opening the switching flap 11 - see FIG. 1 and FIG. 4.

The purification of the polluted air in the target cleaned outdoor space takes place by sucking in the fan 3 through the ventilation suction inlet 4 and the ozonizer 13, where ozone eliminates viruses, bacteria and spores, via the discharge outlet 6 into the target cleaned outdoor space. During this cleaning cycle, the sensor 10 reads the values of temperature, humidity, CO2 content and ozone content in the air. The measured values are displayed by the display element 9 and evaluated with their reference value set by the control program in the form of a recommendation to the operator. After reaching this ozone value in the target cleaned outdoor space, the actuator 7 is actuated by the sensor 10 in the operational control unit 8 by an electric command (current) with the fan 3 running, which closes the switching flap 11, see fig. 1 and FIG. 3 and the actuator 11 changes the air path in the ozone sterilizer with subsequent air regeneration. Then the intake air with a high content zone continues from the intake inlet 4 through the dust filter 14 and the exhaust outlet 6 in the form of oxygen to the target cleaned outdoor space for the time of reaching a suitable health safe oxygen concentration in the target cleaned outdoor space. After reaching this value, the sensor 10 in the operational control unit 8 activates by an electric command (current) the actuator 7, which opens the switching flap 11 - see fig. 1 and FIG. 4, stops the operation of the fan 3, the operating control unit 8 displaying this fact visually and / or acoustically to the operator in the display member 9 and via the router 15 also to the remote control (16), whereby the device is ready in its initial position in the target cleaned outdoor space.

The described and illustrated embodiments are not the only possible embodiments of the technical solution, as the housing 1 may be equipped with a different number of rotating wheels 2 (not shown) or may be without wheels 2, the dust filter 14 may be equipped with a different filter fabric or multilayer of different fabrics, the catalytic filter may have other, e.g. a conical shape or the shape of a truncated cone, or a hemisphere, or a horizontal or one inclined surface, or it can be formed in the form of a block with at least one discharge outlet 6. The fan 3 may be of a different construction, and its discharge part and the switching flap 11 may have a different shape and position as shown.
