Description
Automatic airconditioner disinfection system
The subject of the invention is an automatic airconditioner disinfection system, making possible the elimination of the microorganisms settled in the filter units, air-tube systems and heat exchanger systems of air conditioning equipment, ensuring this way the supply of contagious matter-free, clean air.
Efficient protection against contagious and allergic conditions caused by insufficiently cleaned, or unclean airconditioning equipment has been highlighted more and more nowadays, but it is still an unsolved problem. With the more and more widespread use of airconditioning equipment it is becoming more and more important to free the filter systems as well as the air-duct systems from germs. In the units of the airconditioning systems numerous contagious matters establish themselves and proliferate in the partial units of the air-conditioning equipment resulting from the germs coming from the outside air, but mainly with the breath of people in the inside space, mainly in case of air conditioning equipment operated by feeding back the air of the inside space.
Currently the cleaning and disinfecting of the air-conditioning equipment takes place manually, in such a way, that IBE aerolose desinfecting material is blown into the filter units of the air conditioning equipment. The quality of the cleaning carried out this way depends partly on the thoroughness of the staff carrying out the maintenance, partly due to the shaping of the units of air conditioning equipment they include numerous spaces, that cannot be reached, so the disinfecting material can not get there. Another drawback of the disinfection of this type is, that after blowing in the disinfecting material, only a part of the germs is ruined, namely the complete elimination of the germs settled there cannot be achieved, as in most cases the process of disinfection is too short to ruin all the germs.
According to experts" findings it is not sufficient to clean the air-conditioning systems once a year, and especially not with manual methods bringing subjective results only, but an efficient method cleaning every hollow and surface at least twice, or even several times a year can only ensure the proper elimination of germs.
According to the state of the art the FR2840564 patent publication makes known a motor vehicle air conditioning system has disinfectant reservoir and atomizer nozzle to spray evaporator and eliminate odors. The air conditioning system comprising a series of air ducts and control shutters, a fan, heater, evaporator and drain hose for discharging condensed liquids onto the evaporator. It incorporates a liquid disinfectant reservoir and atomizer nozzle to spray the liquid onto the surface of evaporator before or after air circulation. The disinfectant spray nozzle is actuated by a control linked to the air conditioner control unit.
The FR2920348 patent publication makes known removable disinfection cartridge for heating and air conditioning unit of motor vehicle. The cartridge has rapid attaching unit i.e. groove, for cooperating with a groove provided in an opening of a case of a heating
and air conditioning unit for temporarily fixing the cartridge with the case. Windows are arranged on a peripheral of the cartridge for diffusing a volatile chemical substance e.g. biocide, at an interior of the case, where the cartridge is formed in cylindrical or rectangular shape.
The CN101037081 patent publication makes known ventilation, heating or air- conditioning facility receiving air treatment cartridge by diffusion of volatile treating agent, especially for a vehicle, which is equipped with means for treating the air by diffusion of a volatile agent. This unit comprises a wall bounding an air circuit, this wall having an opening there through for the passage of a treatment cartridge. A permeable partition defines a diffusion chamber for the volatile agent, this partition being placed in the internal volume of the air circuit.
The drawbacks of the solutions described above are, that they do not grant to a proper extent the complete ruining of the microorganisms settled in the filter units of the air- conditioning systems and in the air-conduit system and heat-exchanger.
When working out the solution according to the invention we aimed at creating such an air-conditioner cleaning system, with the help of which it is made possible, that at an optional point of time the destruction of the germs, microorganisms settled in each unit of the air-conditioning equipment can be granted.
We realized, when working out the solution according to the invention, that in case a sufficient quantity of disinfectant in proportion with the cubic capacity of the ducts of the air-conditioning system, is filled into cartridge(s) under overpressure into the air- conditioning unit of the air-conditioning system, or directly next to the air-conditioning unit,
or disinfectant and power gas are put into the air-conditioning unit of the air- conditioning system, or directly next to the air-conditioning unit in separate cartridges or containers, and the quantity of disinfectant and power gas determined in advance is fed into a common feeder unit,
then with interposing a manual or electronic timer switch, at the starting of the starting switch the disinfectant is injected, or the disinfectant and the power gas from the feeder unit through the vaporizer head is injected into the flues of the air-conditioning system by the automatic trimming-off of the cartridge(s) filled with disinfectant,
in given case compressed air-spray can promote the forwarding of the injected disinfectant into the flues,
and the disinfectant is kept for the proper contact time in the flues of the air- conditioning system, then after the contact time elapsed, it is ventillated out of the flues of the air-conditioning system,
furthermore we realized, that in case at the opening of the outlet flue of the air- conditioning unit of the air-conditioning system, or in case of demand at proper points of the flue of the air-conditioning system units, units, lamp(s) radiating ultraviolet light are placed in such a way, that with the help of interposed manual or electronic timers the air going through the full cross-section is transilluminated to the proper level at proper time intervals, then the set aim can be achieved.
The invention is an automatic airconditioner disinfection system, containing a cartridge, disinfectant, a vaporizer head, which is characterized by that, cartridge(s) filled with quantity of disinfectant under overpressure, proportioned to the capacity of the flues of the air-conditioning system are located in the air-conditioning unit of the air- conditioning system, or in the storage unit placed directly next to the air-conditioning unit, where said cartridge(s) is automatically trimmed-off, interposing a manual, or electronic timer switch, in a point of time and order, determined in advance, at the receipt of the signal from the starting switch, and in given case the disinfectant is injected into the flue of the air-conditioning system through the conduit and the vaporizer head, then the disinfectant is kept in the flues of the air-conditioning system for a proper contact time, then after the expiry of the cleaning phase it is removed from the flues of the air-conditioning system by ventillation.
In one preferred realization of the system according to the invention, in case of air- conditioning systems with bigger capacity and flues, the cartridge(s) filled with power gas are placed in the storage unit in order to forward the disinfectant more efficiently into the flues, and said cartridge(s) are trimmed-off in the known way simultaneously with the cartridges containing disinfectant, and getting to the flues of the air- conditioning system together with the disinfectant through the vaporizer head promote the flow of the disinfectant into the flues of the air-conditioning system.
The invention is further an automatic airconditioner disinfection system containing storage tank(s), cartridge(s), disinfectant, power gas, vaporizer head and feeder unit, which is characterized by that, in the air-conditioning unit of the air-conditioning system, or directly next to the air-conditioning unit, in the container, or cartridges disinfectant is placed, whereas in another container or cartridges power gas is placed, from which the disinfectant and the power gas get to the feeder unit, and from said feeder unit the disinfectant and the power gas are injected into the flue of the air- conditioning system through the conduit and the vaporizer head at a time determined by interposing a manual or electronic timer switch, then the disinfectant is kept in the flues of the air-conditioning system for the proper contact time, then after having expired the cleaning phase, it is removed from the flues of the air-conditioning system by ventillation.
The invention is furthermore an automatic airconditioner disinfection system, containing storage container, compressed air, vaporizer head and feeder unit, which is characterized by that, in the air-conditioning unit of the air-conditioning system, or directly next to the air-conditioning unit, in the container, disinfectant is placed, from where the disinfectant gets to the feeder unit, from said feeder unit the disinfectant is injected into the flue of the air-conditioning system at a time determined in advance, b - interposing a manual or electronic timer switch, through the conduit and the vaporizer head, and simultaneously with the injection of the disinfectant into the flue, compressed air is led into the system on the part of the flue behind the vaporizer head for a time period determined in advance, then the disinfectant is kept in the flues of the air- conditioning system for the proper contact time, then after having expired the cleaning phase it is removed from the flues of the air-conditioning system by ventillation.
In one preferred realization of the system according to the invention, the material of the disinfectant is C102, chloramine-T, OP A, benzalkonium-chloride, which materials can be stored in the cartridge under pressure as well.
In another preferred realization of the system according to the invention, the choosing of the material of the power gas is in conformity with the material applied as disinfectant.
In a further preferred realization of the system according to the invention, choosing of the solvent of the disinfectant is in conformity with the material of the applied disinfectant.
In a further preferred realization of the system according to the invention, the contact time of the cleaning phase is determined in conformity with the capacity of the flue of the air-conditioning system, the pressure value of the power gas, as well as the effect mechanism of the disinfectant, preferably this contact time does not exceed 30 minutes.
The invention is furhermore an utomatic airconditioner disinfection system containing unit radiating ultraviolet light, and lamp, which is characterized by that, a unit, and lamp(s) radiating ultraviolet light are placed at the access of the flue leading out of the air-conditioning unit of the air-conditioning system, or in case of demand at the proper points of the flues of the air-conditioning system in such a way, that with the help of the interposed manual or electronic timer switch at proper time periods the surface of the flues and the air flowing through the full cross-section is transilluminated in a proper extent.
The solution according to the invention is furthermore set forth by the enclosed drawings:

Fig 5 depicts a possible realization of the air-conditioner-cleaning system according to the invention with container embodiment.
Fig 6 shows another possible realization of the air-conditioner-cleaning system according to the invention with container embodiment.
Fig 1 depicts a flow diagram of a possible operation of the realization of the air- conditioner-cleaning system according to the invention with cartridge 3 embodiment. The running of the air-conditioner-cleaning system can be seen in the drawing, that is
the starting I of the air-conditioner-cleaning system, the injection BE of the disinfectant 8, then the cleaning phase TI with ensuring the necessary contact time, and following this the ventillation SZE. Resulting from the procedure the required clean TL flues 4 are realized in the air-conditioning equipment.
The starting I of the air-conditioning system can be realized in two ways, either manually, or automatically. During manual starting, the user themselves of the air- conditioner-cleaning system pushes the starting switch 6 operating the air-conditioner- cleaning system for example in a building, or in a car. In case of automatic starting, after having set the time in advance, the starting switch gets into operation the air- conditioner-cleaning system automatically at the set time point.
Accordingly for example the injection BE of the disinfectant 8 starts with the first unit of the cartridges 3 in the storage unit 19 following the receipt of the signal from the starting switch 6 signalling for example, that the cartridge 3 is trimmed-off mechanically and the disinfectant 8 of proper pressure and quantity, situated in the cartridge 3 under overpressure gets to the flues 4 through the conduit 18 and the vaporizer head 10, at optimized points, it is injected BE into the system and there it fills in each hollow evenly. In order to achieve this, the flue 4, and every element, part of the air-conditioning system is formed in such a way, that the path of the flow is optimal, that is the disinfectant 8 can get to each point of the air-conditioning equipment and there could realize its effect.
It is followed by the cleaning phase TI. In the cleaning phase TI the disinfectant 8 injected into the air-conditioning equipment during the contact time, determined in advance in conformity with the disinfectant 8 used, respectively with the formation of the air-conditioning equipment, fills in the full capacity of the flue 4, gets into touch with every element, surface of the flue 4, and the microorganisms (bacteria, alga, fungi, protozones, viruses) are ruined resulting from the effect of the disinfectant 8.
The quantity and pressure of the disinfectant 8 in the cartridge 3 should be determined in such a way, that the disinfectant 8 injected into the air-conditioning system can get to every flue 4 and fill in the flues 4.
When determining the contact time of the cleaning phase TI, the time necessary for destroying the parasitical microorganisms in the air-conditioning system should be taken into consideration. Following the cleaning phase TI the phase of ventillation SZE automatically starts, that is the ventillator, ventillators of the air-conditioning system blow out the disinfectant 8 from the flues 4. This time in case of a car for example, free outlet from the inside of the car for the disinfectant 8 must be ensured.
In case of office buildings of closed system, where the space is closed, where there are no windows that could be opened, there the ventillation system takes out the air mixture containing disinfectant 8 produced by the air-conditioner-cleaning system switched on usually during night-time, on holidays etc. So at the end of the procedure the clean TI flues 4 are granted.
In case of bigger systems, for example buildings, office buildings the air-conditioner- cleaning system should be designed that way, that disinfection of the whole system, or each phase of the disinfection of the required effect is ensured. In order to achieve this, air-conditioner-cleaning systems should be placed at several, suitable parts of the air- conditioning system.
During the operation of the air-conditioner-cleaning system it must be ensured, that the openings of the building are in closed state during starting I, injection BE, cleaning phase TI, respectively no other ventillation system work in the inside space during this time, because this would considerably decrease the process of air-conditioner-cleaning. Following the cleaning phase TI implicitly in the ventillation SZE phase it must be ensured, that the whole quantity of disinfectant 8 is ventillated out from the inside space, either by opening the doors and windows, or with the help of the air-conditioning system.
Fig 2 shows a possible realization of the air-conditioner-cleaning system according to the invention with cartridge 3 embodiment. In the drawing the air-conditioning unit 1 can be seen and the flues 4 and air exit chamber 5 joining it through the distribution space 2. It can be well seen in the drawing, that the vaporizer head 10 formed at the end of the conduit 18 joined the cartridges 3 placed in the storage unit 19 provided with a starting switch 6 is situated protruding into the distribution space 2.
The air-conditioner-cleaning solution with cartridge is primarily suitable to clean air- conditioning systems of cars, but it can be applied in other places, for example in case of air-conditioning systems installed in buildings, if properly installed.
Fig 3 shows a possible embodiment of the filled cartridge 3 before use of the air- conditioner-cleaning system according to the invention, as well as a possible realization of the trimming-off, in section. The cartridge 3 placed in the casing 12 can be seen in the drawing. The disinfectant 8 is placed in the cartridge 3. The cartridge 3 is closed with the help of cartridge closing 13. It can be well seen in the drawing, that the cartridge 3 situated in the casing 12 joins the base 16 provided with sealing 15, and the trimming-off needle 14 joined the conduit 18 is placed in the base 16.
Fig 4 shows a possible realization of the use of the filled cartridge 3 of the air- conditioner-cleaning system according to the invention, as well as another possible realization of trimming-off, in section. The cartridge 3 placed in the casing 12 can be seen in the drawing. The disinfectant 8 is placed in the cartridge 3. The cartridge 3 is closed with the help of the crtridge closing 13. It can be well seen in the drawing, that the cartridge 3 situated in the casing 12 joins the base 16 provided with sealing 15, and the trimming-off drift 17 is placed in the base 16 and the conduit 18 is situated leading out of the part of the storage unit 19 of the base 16.
Fig 5 depicts a possible realization of the air-conditioner-cleaning system according to the invention with container embodiment. The cartridge 3 filled with disinfectant 8 as well as the container 20 filled with power gas 7 can be well seen in the drawing. Following the feeding and mixing of the power gas 7 and disinfectant 8 into the feeder
unit 11 they are injected through the conduit 18 and the vaporizer head 10 into the flue 4 of the air-conditioning system, into the heat-exchanger. The power gas 7 can be stored if needed in the cartridge 3 and the disinfectant 8 can be stored if needed in the container 20.
The air-conditioner-cleaner system with container described above can not be applied in case of cars, because it needs a lot of space. This solution can be primarily applied in air-conditioning systems installed in buildings, as its advantage is, that big quantities of power gas 7 and disinfectant 8 can be stored in the containers 20.
Fig 6 shows another possible realization of the air-conditioner-cleaning system according to the invention with container embodiment. The container 9 filled with disinfectant 8 can be seen in the drawing. The disinfectant 8 is sprayed in the feeder unit 11 , then through the conduit 18 and vaporizer head 10 it is injected into the flue 4. This case as no power gas 7 is used, the proper forwarding of the disinfectant 8 into the flues 4 is ensured by blowing in compressed air SL. The feeder unit 11 can be operated electrically, or pneumatically.
The air-conditioner-cleaner system with container described above can not be applied in case of cars, because it needs a lot of space. This solution can be primarily applied in case of air-conditioning systems installed in buildings, as its advantage is, that big quantities disinfectant 8 can be stored in the container 9.
In case of a possible preferable application of the air-conditioner-cleaner system according to the invention, preferably a storage unit 19 is built in to a determined part of the car, preferably near the air-conditioning unit 1, and the cartridges 3 placed in the casing 12 containing the disinfectant 8 are put into the storage unit 19. The casings 12 of the cartridges 3 are fixed to the bases 16. For the sake of refilling, it is preferable to place as many cartridges 3 as possible, because this case the used patrons do not have to be replaced so frequently with filled cartridges 3.
The cartridges 3 are fixed to the conduit 18 placed in the storage unit 19 through the trimming-off needle 14 formed in the base 16, fixed to the casing 12.
The automatic air-conditioner-cleaning system starts operation with the help of the starting switch 6, which can take place manually, or with a switch with a timer. Resulting from the starting I process the cartridge closing 13 of the cartridge 3 if trimmed-off in the known way, namely the trimming-off needle 14 trims-off the cartridge closing 13 and the disinfectant 8 proportioned to the volume of the conduits of the air-conditioning system, under proper overpressure is injected through the trimming- off needle 14 into the conduit 18, then through the conduit 18 it is led into the vaporizer head 10 placed protruding into the distribution space 2.
Following this the disinfectant 8 gets from the distribution space 2 this case into each flue 4, filter, air exit chamber 5 of the car and fills them. Following this the cleaning phase TI takes place, when the disinfectant 8 is kept in the air-conditioning system for a
contact time determined in advance resulting in the ruining of the microorganisms settled in every spare unit of the air-conditioning system.
After the contact time is over, the ventillator of the air-conditioning unit 1 is automatically switched on, resulting in the removal of the disinfectant 8 carrying out the disinfection from all the flues 4 of the air-conditioning system. To ensure the proper removal it is preferable to open the doors of the car, or pull down the windows.
After the ventillation SZE took place, the air-conditioning equipment forwards clean air into the car.
The above procedure should be preferably repeated at least once or twice yearly, but resulting from individual requirements it can be done more frequently.
In case of a repeated procedure implicitly always the next cartridge 3 is to be used.
In case of another preferable application of the airconditioner disinfection system according to the invention the power gas 7 in the container 20 and beside it in another container 20 the disinfectant 8 are preferably placed to a definite part of the building where the air-conditioning system is working, close to the air-conditioning unit 1. The power gas 7 and the disinfectant 8 get to a common space, to the feeder unit 11 through a tube-system from the containers 20, in such a way, that the quantity of power gas 7 and disinfectant 8 to get to the feeder unit 1 1 is controlled, regulated by an interposed electronic timer. This quantity can be determined in the feeder unit 11 conforming with the size and container type of the air-conditioning equipment.
In the feeder unit 11 the power gas 7 and the disinfectant 8 get mixed, then with the help of the feeder unit 1 1 the mixture is forwarded to the vaporizer head 10 through the conduit 18, where it is injected into the flue 4 of the air-conditioning system with the help of the vaporizer head 10, and is forwarded to every permeable unit of the air- conditioning system.
It is followed by the cleaning phase TI, when the disinfectant 8 in the air-conditioning system is kept in the system for a contact time determined in advance, resulting in the ruining of the microorganisms settled in every partial unit of the air-conditioning system.
After the expiry of the contact time, the ventillator of the air-conditioning unit 1 is automatically switched on, resulting in the removal of the disinfectant 8 from all conduits of the air-conditioning system by blowing out. In this procedural phase it must be made sure, that the disinfectant 8 is definitely removed from all the spaces of the building ensuring disinfectant 8 free air for the people in the building.
The above procedure should be preferably repeated at least once or twice yearly, but resulting from individual requirements it can be done more frequently.
As in this case the power gas 7 and the disinfectant 8 are stored in containers 20 of big size, so this way it is ensured, that the refilling can take place less frequently. In given case it is preferable to install a level indicator in these containers 20, or a pressure indicator with the help of which the quantity inside can be followed.
In case of another possible preferable application of the airconditioner disinfection system according to the invention the container 9 is preferably placed to a definite part of the building where the air-conditioning system is working, preferably close to the air- conditioning unit 1, or in case of an air-conditioning unit 1 of big size, into the air- conditioning unit 1 itself. This case the disinfectant 8 is placed into the container 9.
At the starting I of the airconditioner- disinfection, the disinfectant 8 is fed with the help of the feeder unit 1 1 through the conduit 18 from the conainer 9 into the vaporizer head 10 where it is injected into the flue 4 of the air-conditioning system. This case the disinfectant 8 is forwarded to the units of the air-conditioning system, the compressed air SL is blown into the flue 4 close to the vaporizer head 10.
In case of this solution electronic timer controls the quantity of disinfectant from the feeder unit 1 1 to the air-conditioning system. The determination of the quantity is made in the feeder unit 1 1, depending on the size of the air-conditioning system and the container 9.
Dimensioning is necessary in case of buildings installed with air-conditioning systems to decide the quantity of disinfectant 8 to be forwarded to the system, and depending on the diameter and length of the conduit, what quantity of power gas can ensure, that the disinfectant 8 get to each point of the system. In conformity with it in case of buildings of several levels installation of one air-conditioner- disinfection system on each level, or in given case more is justified.
In case of another preferable application of the airconditioner disinfection system according to the invention, to ensure the efficiency of the cleaning of the flues of the air-conditioning system, as well as to prevent the germicide nucleation, a germicide lamp of LED formation, radiating ultraviolet light is placed on a definite point, or points of the air-conditioning system of the building, or car installed with air-conditioning system, preferably into the flue 4 leading out of the air-conditioning unit 1 in a protruding way, or in a way forming the same surface with the inside surface of the flue 4. Resulting from the ultraviolet light a considerable part of the microorganisms is ruined in the air going through a given cross-section, so it can be ensured, that no microorganisms settle in the conduits of the air-conditioning system, and no germicide nucleation takes place.
When locating the lamp radiating ultraviolet light, it must be made sure, that it light the whole surface of the flue 4, that is the air going through the whole surface of the cross- section is treated.
In case of bigger air-conditioning systems, it is preferable to place lamps radiating ultraviolet light on several places.
The automatic airconditioner disinfection system according to the invention forwards quantities of cleaning disinfectant 8 conforming with the parameters of the given air- conditioning equipment into the air-conditioning system within time periods determined in advance, in given case with manual operation, combined with suitable timer system,
or automatic electronic warning system, in such a way, that even in points of hidden location and unfavourable flow-limiting passages the disinfectant can appear and during the proper contact time it can achieve the necessary effect, namely the ruining of the microorganisms to a proper extent.
Choosing the right disinfectant 8 is a very important parameter from the point of view of the efficient operation of the system. The disinfectant 8 has to meet with numerous requirements, like storability (chemical stability in time), solubility in the solvents to be possibly used in proper concentration, toxic characteristics relating to humans, its concentration, temperature, pH value, etc.
The disinfectant 8 applied must conform with the requirements of being non-toxic for humans, should be stabile enough to be stored for a relatively long time, it should be corrosion-proof, should have no harmful by-product during application, as well as the by-products could be easily removed from the air-conditioning system.
The material of the disinfectant 8 can be:
Chlorine-free oxidants: potassium permanganate, hydrogen peroxide, ethylene- oxide, ozone
- Aldehydes: formaldehyde, glutaric aldehyde, ortho phtalaldehyde
-Heavy metal salts
-Compounds with chlorine content: chlorine gas, hypochlorites, mono chloramine, chloramine-T, chlorinedioxide
Alcohols
Phenol derivatives
Quaternary ammonium compound: benzalkonium chloride, chlorine hexidi but preferably: C102, chloramine-T, OP A, benzalkonium-chloride which can be stored under pressure in the cartridge 3.
The solvent of the disinfectant 8 must be chosen in conformity with the material of the disinfectant 8.
The material of the power gas 7 must be chosen in conformity with the material of the disinfectant 8. For example in case of a disinfectant 8 of CL02 material the power gas 7 is preferably compressed air SL, whereas in case of chloramine-T, OP A, benzalconium- chloride nitrogen, argon, or air is preferably used as power gas 7.
When choosing the materials for the cartridge 3, container 9, feeder unit 11 , container 20, the materials of the power gas 7 and the disinfectant 8 must be taken into consideration, so they can be aluminium, stainless steel, steel, preferably plastic.
In case of the automatic air-conditioner disinfection system according to the invention, when choosing the injector device and its vaporizer head 10, the characteristics, density, consistency etc. of the disinfectant 8 applied must be taken into consideration, to make sure, that the disinfectant 8 can be pulverized with the vaporizer head 10 in the proper extent, and the disinfectant 8 can be pulverized to drops of proper size. As pneumatic vaporizers can ensure the smallest drop size, so this is the most favorable from the point of view of disinfecting air-conditioning equipment.
The pressure of the power gas 7 stored either in the cartridge 3 or in the container 20 is determined in conformity with the shape of the vaporizer and its vaporizer head 10, the required size of the drop of the sprayed disinfectant 8, and the capacity of the flues 4 of the air-conditioning system. When planning the pressure it must be made sure, that the volume of the power gas 7 at atmospheric pressure does not exceed the volume of the inside space of the air-conditioning system, because then the power gas 7 ensuring the flow of the disinfectant 8 can blow it out.
On basis of our preliminary tests the contact time did not exceed 30 minutes in case of application of any of the disinfectants 8 to achieve proper effect, as the quantity of the disinfectant 8 and the pressure of the power gas 7 were adjusted to the capacity of the air-conditioning system, so the contact time is similar.
The automatic airconditioner disinfection system according to the invention can be produced with two solutions. In case of smaller space, primarily in case of disinfecting air-conditioning equipment of cars, the disinfectant 8 is placed in a cartridge 3.
This case when pushing the starting switch 6, or with automatic starting the cartridge 3 placed in the storage unit 19 is trimmed-off, implicitely in case of subsequent operations always the next cartridge is trimmed-off and injected into the system, which starts functioning, and the disinfectant 8 in the system carries out the procedure of disinfectioning under the optimal pressure, determined in advance, getting to the most critical hollows through the optimized conduits. From health safety reasons the cleaning movement can be carried out in stationary vehicles only, preferably in the evening, or before several hours stand-still to ensure enough time for the disinfectant 8 to leave the system. Following the relief of the cartridges 3 appr. after 10-60 minutes the ventillators automatically blow out the disinfectant 8 from the air-conditioning system.
In case of bigger cars, buses, where the flue 4 of the air-conditioning system is considerably bigger, there simultaneous use of more than one, two, or three cartridges 3 is necessary.
In case of air-conditioning equipment of bigger size it is preferable to store the disinfectant 8 and the power gas 7 in separate, bigger size containers 20 to ensure sufficient quantity of raw material for carrying out disinfection several times. The electronic timing is necessary in case of both versions to synchronize ventillation.
In case of the automatic airconditioner disinfection system according to the invention the flux system has to conform with the given air-conditioning system, namely the planning of the optimal route of the disinfectant 8 in such a way, that it gets to each surface of the air-conditioning system, so there can be no hidden, or unaccessible hollows in the system. Implicitly the quality, quantity of the power gas 7 must be determined accordingly, or ensure, that in case of a disinfecting procedure the proper quantity of power gas 7 leaves the container 20.
The starting I phase of the cleaning process must be planned in conformity with the air- conditioning system of given application, as well as the individual requirements, namely
whether the starting I phase is initiated manually, or automatically. In case of automatic starting I phase, it must be determined in advance how often, every half-year, every month, which time of day, which calender day, eg. Saturday night etc. the cleaning movement is repeated.
The advantage of the solution according to the invention is, that the efficiency of the automatic airconditioner disinfection system does not depend on the consciousness, or thoroughness of the staff carrying out the movement. Primarily the efficient, more advantageous use of air-conditioning equipment in the automotive industry can be achieved by this, aiming at healthcare requirements and conforming with higher convenience requirements as well. The sysem is suitable as well for cleaning air- conditioning systems not used in the automotive industry. A further advantage of the invention is, that the cleaning procedure can be easily carried out several times a year as well.
The advantage of the airconditioner disinfection system functioning with ultraviolet light is, that it can be used any time, even is continous operation, in case of cars even under way. In case of this solution the possibility of failure is smaller, supply of disinfectant and power gas is unnecessary, and it is more advantageous from health safety point of view compared with the application of chemicals.
