TECHNICAL FIELD

This application relates to equipment for sanitizing the air conditioning system and interior of vehicles in general through the transformation of the ambient air into a purifying plasma primarily containing hydrogen peroxide and hydroxyl radicals.


SUMMARY

In BR 102012001122-0—the generation of the plasma is achieved through the phenomenon of radiant catalytic ionization, when air passes through a UVX lamp enclosed by a hive impregnated with noble metals, with emphasis on titanium dioxide.


In BR 102012001122-0—the air is drawn into the interior of the equipment by means of a fan adjacent to a protective grating which is activated simultaneously with the UVX lamp when the ON-OFF switch is switched on.


In BR 102012001122-0—the application of the plasma for a predetermined period of time can be performed at two different speeds selected with a control button.


In BR 102012001122-0—the portability of the equipment facilitates the maneuverability and positioning thereof directly on the interior of the vehicle where it takes place or in the inlet region for air conducted to the air conditioning system.


Using the same inventive concept as BR 102012001122-0, this certificate of addition provides for the compacting of the equipment in two modules with the purpose of being used onboard automobiles and other means of transportation. By virtue of a more compact design, it is possible to perform the installation of the UVX lamp module by incorporating and/or installing it at a strategic point along the path traveled by the air used in the air-conditioning of the vehicle.


The tables below show tests that corroborate the efficacy of the equipment when employed in a passenger vehicle in terms of the concentration of fungi and bacteria, and the measurement of direct readings for temperature, humidity, volatile organic compounds, carbon monoxide, particulate matter and formaldehydes. The tests were conducted on two vehicles—one with the equipment and one without it.

DETAILED DESCRIPTION

The “EQUIPMENT FOR SANITIZING THE AIR CONDITIONING SYSTEM OF VEHICLES BY MEANS OF RADIANT CATALYTIC IONIZATION” which is an object of this certificate of addition includes the compacting of the equipment into two modules (1 and 2) on a scale small enough so as to enable installation of the modules directly in the air conditioning system of transportation vehicles or other means of transportation.


More particularly, the equipment (E) of this addition of compact design is best represented by a module (1) containing the UVX lamp (3), and another module (2) with the cell (4) with the respective components responsible for the powering and controlling the functions of the lamp itself. Such modules (1 and 2) are preferably distinct so as to enable installation of module (1) of the UVX lamp (3) at a strategic point [along the path] traveled by the air used in the air-conditioning of the vehicle. Thus, when the air passes through the UVX lamp (3) and the hive (5), which is impregnated or coated with a noble metal alloy. The air coming from the forced ventilation of the vehicle undergoes a radiant catalytic ionization reaction, generating purifying plasma with a high level of sanitizing power, not just for the air conditioning system, but for sanitizing the entire vehicle compartment. The first module (1) comprises of a frame (6) with covering (7) and lateral outlets (8) for the passage of air through the hives (5) and the UVX lamp (3), whereas the second module (2) is also formed by frame (9) and covering (10) receiving the components of the cell (4).


In this context, when the air conditioning system is switched on, the UVX lamp (3) is lit, thus bringing about the transformation of the air into purifying plasma composed of hydroxyl radicals and hydrogen peroxide. The purifying plasma can be applied according to the ventilation speeds of the air conditioning system of automobiles, and its respective resources, depending on the vehicle.


Moreover, the equipment (E) can also be applied in the air conditioning systems of other land, sea or air vehicles such as, for example, trains, subways, boats, airplanes, etc.
