Description
DETACHABLE FILTER FOR AIR CONDITIONING SYSTEM AND
INS TALLAT ION METHOD
The present invention relates to a detachable filtering apparatus for an air conditioning system and to an installation method thereof. In one embodiment a circular frame and a multi-aperture filter screen are installed at a specified installation area of the air tube of the air conditioning system. The effect is better than the results of prior art air cleaning using conventional chemicals.
In the food industry, an aseptic environment is an important factor. Furthermore, air-disinfection and air-purification are the most important goals for an air conditioning system. The methods include producing ozone, negative ions and photocatalytic bactericidal material etc. An airconditioning system is suitable for industrial factories, commercial buildings and homes and disinfects the air. For example, a food factory is a place that easily propagates bacteria.
Installing an air-disinfection and purification apparatus can help prevent outbreaks of infectious diseases.
Similarly, in commercial buildings, such as market buildings, the air easily accumulates bacteria due to the exhibition of food (in particular, workers are at risk during maintenance) . Installing an air- disinfection purification apparatus helps disinfect the air. In private homes, an air conditioning system has an air-disinfection and purification goal to assure the inhabitants of the house that the air they are breathing is clean and healthy. Therefore, an air- disinfection and purification apparatus is a basic technology and is necessary for any air conditioning system. The construction method is an important factor for an air conditioning system manufacturer. The focus is on improving the practicality of the structure of the air-disinfecting and purification apparatus and reducing the cost of the operation.
Conventional indoor air cleaning methods, for preventing and sterilizing bacteria infections in a multi-storey building, require a drug-spraying washing tower and a harmful gas absorbing device at the vent of O the multi-storey building. However, such methods require a medium-sized chemical barrel. While this may be suitable for a food or a chemical factory with lots of extra space, for a medium-sized or a small-sized building, this requirement is inconvenient and there is a need for improvement.
Therefore, an air-disinfecting and purification apparatus must have powerful disinfection ability, its structure needs to be compact and it must fit in with the natural principles of airflow. A convenient installation method at low cost allowing easy removal and maintenance is also desirable.
An object of the present invention is to provide an air cleaning apparatus that is easily installed and removed.
The invention is defined in the independent claims.
In one embodiment the air cleaning apparatus has a filter structure having a quaternary ammonium disinfecting function. It is suitable for existing air conditioning systems and is cheap. The filter structure can be applied to an air conditioning system in hospitals, industrial buildings, commercial buildings, houses and vehicles for example. The present invention enables a low cost quaternary ammonium material to be used in existing air conditioning systems to reduce costs, and works well.
In one embodiment the filter apparatus of the prevent invention includes a multi-aperture filter screen and a circular frame. The multi-aperture filter screen fits in with the circular frame and is installed in the airing area of the air conditioning system. The installation method is easy and allows easy maintenance. Furthermore, a quaternary ammonium salt disposed/affixed onto the multi-aperture filter screen and passes through the holes of the multi-aperture filter screen via airflow. The preferred embodiments of the present invention utilizes air convection in the inlet and outlet, or the pipes of the air conditioning system to form a filter structure for the air conditioning system having a quaternary ammonium salt disinfection function. A manufacturing method is also disclosed.
One embodiment of the present invention includes a multi-aperture filter screen having a rim fixing area and a filtering area, and a frame (which can be circular or square for example) . Its size matches with the inner edge of a specified installation area of an air pipe of the air conditioning system. The frame is installed at the specified installation area and can be detached. The center of the frame is the air flowing area. At the filtering area there is quaternary ammonium compound that combines with the multi-aperture filter screen via chemical bonding. Plternatively, when the quaternary ammonium compound is not reactive, the quaternary ammonium compound combines and attaches with the multi-aperture filter screen via an interface- linking method.
In the preferred embodiment the detachable frame is located at a fixing area on the vent of the air conditioning system. The filtering area is installed on the center air flowing area of the frame. The frame installed with the multi-aperture filter screen is implemented by tightly pressing the rim fixing area via an outer frame portion, or by an adhesive method, a metal screen melting connecting method or a fastener fastening method. This makes the rim fixing area integral with the frame. The multi-aperture filter screen is installed in the detachable circular by a pressing method, an adhesive method, a metal screen melting connecting method or a fastener fastening method. Thereby, the compound reacts with the air at the vent flows to disinfect the air. The quaternary arnmonium compound attached at the filtering area reacts with the air at the vent flows to disinfect the air.
One method in accordance with the present invention includes: (1) manufacturing the multi- aperture filter screen and a circular (or differently shaped) frame, and (2) installing the multi-aperture filter screen and the circular frame at a specified installation area of an air pipe of the air conditioning system. When the detachable circular frame installed with the multi- aperture filter screen is implemented by tightly pressing the rim fixing area via the outer frame, the rim fixing area is clipped between the specified installation area and the outer frame.
When the detachable circular frame installed with the multi-aperture filter screen is implemented by an adhesive method, a metal screen melting connecting method or a fastener fastening method, it makes the rim fixing area integral with the circular frame, so the rim fixing area is fastened at an outer frame. Then, the outer frame is installed at the specified installation area.
For further understanding of the invention, reference is made to the following detailed description illustrating the embodiments and examples of the invention. The description is only for illustrating the invention and is not intended to be considered limiting of the scope of the claim.
The drawings included herein provide a further understanding of the preferred embodiments of the invention.

Please refer to FIGs. 1, 2D and 3B, which show an exploded view of an embodiment of the present invention. Please refer to FIGs. 2A, 2B and 2C, which show three structures of a square-shaped multi-aperture filter screen. Please also refer to FIG. 3A, which shows a part combination view of an embodiment of the present invention. At a specified air flowing area of an air tube of an air conditioning system there is a multi- aperture filter screen 20 having a rim fixing area 22 and a filtering area 24, and a circular frame 10 (the circular frame 10 in FIG. 1 is bonded with the multi-aperture filter screen 20, then an installation fitting part 32 is placed for being installed at a specified installation area 30) having an outer frame which size matches the inner edge of the specified installation area 30 of an air pipe of the air conditioning system.
The circular frame 10 is installed at the specified installation area 30. (The circular frame 10 in FIG. 3A is placed into a fitting ring 11 and is installed at the specified installation area 30 and can be detached via a fitting ring base 12) . The center of the circular frame 10 is the air flowing area. At the filtering area 24 there is quaternary arnmonium compound that combines with the multi-aperture filter screen 20 via chemical bonding, or when the quaternary arnrnonium compound is not reactive, the quaternary ammonium compound combines and attaches with the multi-aperture filter screen 20 by an interface-linking method. The fixing area 22 is located at the detachable circular frame 10 on the vent of the air conditioning system.
The filtering area 24 is installed on the center air flowing area of the circular frame 10. The circular frame 10 installed with the multiaperture filter screen 20 is implemented by tightly pressing the rim fixing area 22 via the outer frame, or by an adhesive method, a metal screen melting connecting method (e.g. welding, brazing or soldering) or a fastener fastening method (i.e. using mechanical fasteners such as bolts), and makes the rim fixing area 22 integral with the circular frame 10.
The multi-aperture filter screen 20 is installed in the detachable circular frame 10 by a pressing method, an adhesive method, a metal screen melting connecting method or a fastener fastening method.
Thereby, the compound reacts with the air at the vent flows to disinfect the air. The quaternary arnmonium compound attached at the filtering area reacts with the air at the vent flows to disinfect the air. Then, owing to the inner air pressure difference inside the air conditioning pipe, the air disinfecting process continuously takes place.
Please refer to FIGs. 4A, 4B, 4C and 4D, which show four structures of the multi-aperture filter screen with a cotton screen and a metal screen of an embodiment of the present invention. At a specified air flowing area of an air tube of an air conditioning system there is a multi- aperture filter screen 20 (including a woven-type multi-aperture filter screen 201 and a metal-screen-type multi-aperture filter screen 202) . The woven- type multi-aperture filter screen 201 can be a cotton or woven cloth filter screen and there can be either one or more than one. The metalscreen-type multi-aperture filter screen 202 is made of metal or wire mesh of different sizes and there can be either one or more than one. The filtering area 24 is fastened via an installation-pressing batten 321.
The woven-type filtering area 241 and a metal- screen-type filtering area 242 individually execute a fine filtering and a coarse filtering. The filtering screen 20 in FIGs. 4A, 4B, 4C and 40 can be planar or folded. The specified installation area 30 and the installation fitting part 32 have an outer frame whose size matches with the inner edge of a specified installation area 30 of an air pipe of the air conditioning system. The installation fitting part 32 is installed at the specified installation area 30 and can be detached. The center of the filtering area 24 is an air flowing area. At the filtering area 24 there is quaternary ammonium compound combines with the multi- aperture filter screen 20 via chemical bonding, or when the quaternary ammonium compound is not reactive, the quaternary ammonium compound combines and attaches with the multi-aperture filter screen 20 by an interface- linking method. The fixing area 22 is located at the detachable circular frame 10 on the vent of the air conditioning system. The filtering area 24 is installed on the center air flowing area of the circular frame 10. The specified installation area 30 installed with the multi-aperture filter screen 20 is implemented by tightly pressing the filtering area 24 with a retaining batten 321, or by an adhesive method, a metal screen melting connecting method or a fastener fastening method, and makes the filtering area 24 integral with the frame of the specified installation area 30 or the installation fitting part 32. The woven-type filtering area 241 is installed via the pressing method and the metal-screen-type filtering area 242 is 1nstalled by a metal screen melting connecting method or a fastener fastening method.
The multi-aperture filter screen 20 is installed in the detachable installation fitting part 32 by a pressing method, an adhesive method, a metal screen melting connecting method or a fastener fastening method. Thereby, the compound reacts with the air at the vent flows to disinfect the air. The quaternary arnrnonium compound attached at the filtering area reacts with the air at the vent flows to disinfect the air.
Then, owing to the inner air pressure difference inside the air conditioning pipe, an air d.isinfecting process takes place continuously.
A method of manufacturing a multi-aperture filter screen 20 for an air conditioning system of the present invention is described. Firstly, a quaternary amrnonium salt liquid is manufactured. The quaternary ammonium salt is mixed with water for dilution, and is stirred and dissolved. To create a non-reactive solution, an interface-linking agent can be added. A multi-aperture carrier is soaked in the quaternary ammonium salt liquid. Then, the multi-apertures carrier is removed, and an attaching and drying procedure is performed at temperatures between 30 degrees C and 120 degrees C (between 60 and 80 degrees C is the most effective) for between 3 and 30 minutes. Alternatively, the quaternary ammonium salt liquid is sprayed onto the multi- apertured carrier and the attaching and drying procedure is performed at the same temperature and for the same amount of time as described above.
The air conditioning apparatus can be disposed at an opening of a central air conditioning system, a dehumidifier or an air conditioner. Furthermore, it can also be installed in vehicles, such as the vents of air conditioners on trains, buses, airplanes or ships.
When the multi-aperture filter screen 20 has glass fiber components, the glass fiber reacts with a reactive silicon-alkyl quaternary ammonium salt to form an O-Si-O covalent bond. This solution is extremely difficult to remove. The fiber material is suitably HEPA or tJLPA (an ultra particulate air filter) Alternatively, an unreactive quaternary arnmonium salt adds an interface-linking agent that combines with and attaches onto the fiber. Therefore, the quaternary arnmonium salt cannot be washed away when the air conditioning system is cleaned.
The quaternary ammonium salt on the multi- aperture filter screen 20, which is installed at the vent of the air conditioner, utilizes the circulation of the air at the vent to disinfect the air continuously.
In one embodiment the method of the present invention includes: (1) manufacturing the multi- aperture filter screen 20 and the circular frame 10, and (2) installing the multi-aperture filter screen 20 and the circular frame 10 at a specified installation area 30 of an air pipe of the air conditioning system.
When the detachable circular frame 10 installed with the multi-aperture filter screen 20 is implemented by tightly pressing the rim fixing area 22 via the outer frame, the rim fixing area 22 is held between the specified installation area 30 and the outer frame.
When the detachable circular frame 10 installed with the multi-aperture filter screen 20 is located by an adhesive, a metal screen melting connecting method or a fastener fastening method, it makes the rim fixing area 22 integral with the circular frame 10, so the rim fixing area 22 is fastened at the outer frame. Then, the outer frame is installed at the specified installation area 30.
One installation method in accordance with the present invention (the installation method as shown in FIGs. 4A-'4D) includes: (1) manufacturing the multi- aperture filter screen 20 and the installation fitting part 32, and (2) installing the multi-aperture filter screen 20 and the installation fitting part 32 at a specified installation area 30 of an air pipe of the air conditioning system. When the detachable installation fitting part 32 installed with the multi- aperture filter screen 20 is implemented by tightly pressing the filtering area 24, or by an adhesive method, a metal screen melting connecting method, or a fastener fastening method, it makes the filtering area 24 integral with the frame of the specified installation area 30 or the installation fitting part 32.
