Definitions
- the invention relates to an air-conditioning device for sterilization of air, the environment, and objects by ozone with automatic subsequent regeneration of ozone- degraded air by means of sensors, filtration, electrostatic and catalytic reaction.
- the polluted atmosphere greatly affects public health. It causes a sudden onset of diseases such as cancer, asthma, allergies or irritations, rhinitis, COVID viruses, SARS, and MERS. A person spends up to 70% of the time indoors (in apartments, work, school, etc.). Therefore, the pollution of this space 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 the body and health is therefore at risk.
- the causes of an overloaded immune system most often include fatigue, allergies, and diseases.
- Air pollution in enclosed spaces occurs usually in form of large, small, and gaseous particles.
- Large particles are transferred, especially on clothing, shoes or are blown inside 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 can also be found in the indoor environment created by human activity, such as vacuuming, cutting, grinding, cooking (flour-baking ...), or powdering and the like. Small particles are carried and blown in the form of smoke, pollen, bacteria, viruses, spores, fungi, and the like. They are also created by smoking, cooking, burning in a fireplace, by lighting 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 created by the release of materials and human activity.
- a commonly known filter devices use a filter cloth and these can filter out coarse impurities but cannot filter out fine and gaseous impurities.
- ozone generators which use high electrical voltage to produce ozone into the interior in order to remove viruses, bacteria, and spores from the surfaces of objects.
- ozone is dangerous at certain concentrations, so it is necessary to ventilate the area for a long time after application.
- a technical solution according to DE19902825 is known, which relates to a reactor for the decomposition of ozone (03), which is created in e.g. in photocopiers, ultraviolet sterilizers, and similar electrical equipment.
