Abstract

Description
AIR DUCT WITH ANTIBACTERIAL AND ANTIVIRUS FEATURES Technical Field
The invention relates to air ducts used in heating, cooling and air transfer systems.
The invention especially relates to the formation of an additional silver ion layer with antibacterial properties on the inner layer surface of the air duct which is in contact with the air.
Prior Art Today, flexible air ducts are used in low and medium pressure air transfer systems, heating, cooling, ventilation and similar systems. These air ducts are made of materials such as aluminum, polyester, opp, pvc. These air ducts are formed by shrinking and clamping together. Existing ducts have the ability to bend, fold, stretch and flexion. They are used in oval and round joints. Although flexible air ducts are relatively free of bacteria and pollution today, the duct loses its hygienic properties due to deformations in the inner layer material over time.
In the flexible air ducts used in the state of the art, bacteria and dirt occur over time especially on the inner layer surface. The formation of bacteria and dirt in the flexible air ducts causes the air carried in the air ducts to be hygienically unhealthy. Considering that flexible air ducts are widely used in hospitals, shopping malls and similar environments where hygiene is important, the air coming from the air conditioners causes contact with bacteria, viruses (corona, etc.) and therefore, due to the contaminated air containing bacteria and viruses carried by the air pipes, the risk of contamination of harmful bacteria and viruses is increasing.
A patent similar to the product subject to the invention was not found in the patent research. As a result, the insufficiency of existing solutions made it necessary to make an improvement in the relevant technical field. Object of the Invention
The main object of the invention is to create an additional silver ion layer with antibacterial and anti-virus (corona, viruses, etc.) properties on the inner layer surface of the air duct that enables air to be transported.
Another object of the invention is to develop air duct comprising a silver ion layer which does not contain bacteria and impurities.
Another object of the invention is to develop an air duct with a silver ion layer that prevents deformations that may occur on the inner wall of the air duct.
Another object of the invention is to develop an air duct with a silver ion layer that is carried in the heating, cooling and ventilation systems and enables the air leaving the system to be hygienic.
Another object of the invention is to develop an air pipe with a silver ion layer for use in sterile places where clean room standards are sought and the other places such as shopping malls, hospitals, operating rooms, intensive care rooms, laboratories, medicine and food industry.
Another object of the invention is to develop an air pipe with a silver ion layer that prevents the formation of rust and dirt accumulating on the duct inner layer surface due to airborne particles and moisture.

Detailed Description of the Invention
The invention relates to the formation of an additional silver ion layer with antibacterial/antivirus properties on the inner layer surface of the air ducts (A) used to transport air in heating, cooling and air transfer systems.
ln order to make the pipes flexible, there are wires (4) at certain intervals between the outer layer (1) and the inner layer (2) on the air ducts (A). Said wires (4) are in the form of a spiral. There is an outer layer (1) in the outer part of the air duct (A) surrounding the said wires (4) and an inner layer (2) in the inner part. The antibacterial/antivirus layer (S) containing silver ions is laminated on the surface of the said inner layer (2) and outer layer (1).
The silver ions contained in the antibacterial/antivirus layer (S) are in deactivated position under normal conditions, and become active when they are exposed to bacteria or virus reproduction or humid environment and it kills organisms such as bacteria, viruses. Therefore, together with the air carried in the air ducts (A), the growth of bacteria and viruses that may threaten health is prevented. Thus, the accumulation and transport of bacteria and viruses in the air ducts (A) is prevented. In this way, the cleaning of the transported air, which is important for health, is provided for long periods. Said inner layer (2) and outer layer (1) are made of aluminum foil, polyethylene film, polyester film, opp film, PVC film and similar materials. In Figure 4, a schematic view showing the production process of the subject air duct (A) is given. The production line (5) shown in Figure 4 is used forthe production of the inventive antiviral flexible air duct (A). The production line (5) comprises a gluing section (5.S) where the materials coming from the first uncoiler (5.1) and the second uncoiler (5.2) are combined to each other.
The material, which is combined into a single layer by being combined in the gluing section (5.3), is passed in front of an antiviral surface spraying section (5.4). In the meantime, an antiviral agent containing silver ions is applied by spraying on one surface of the material. Afterwards, the antiviral applied raw material (5.5) and the wire (5.6) coming from a wire unwinding unit (5.8) enter a flexible duct production section (5.7) and the production of the flexible air duct (A) according to the invention
is completed.
The samples of the product subject to the invention were tested at Yeditepe University Biocidal and R&D Laboratory on 08.01.2021, and it was determined that it caused at least 0.74 log (82%) reduction against Bovine Coronavirus in all experimental conditions at 25 0C in 5 minutes of contact time (See, Annex 1).
