Definitions
- the invention relates to an air cleaner.
- the invention relates to an air cleaner, which is designed for cleaning air in an interior of a building such as a living room, an office, conference room or the like.
- An air cleaner is known from CN105605687A, comprising a housing, an inlet formed in the housing, which is designed for admitting air into the housing, an outlet formed in the housing, which is designed for discharging air from the housing, an in a blower arranged in the housing for generating an air flow that flows from the inlet to the outlet, and at least one filter that is designed to clean the air flow flowing from the inlet to the outlet.
- the air cleaner also has a humidifier, a dehumidifier, a heat exchanger, one
- Control device and a sensor device with a moisture sensor Control device and a sensor device with a moisture sensor
- the filter also filters pollutants such as dust, bacteria and toxic gases from the air.

- the advantages that can be achieved with the invention include, in particular, reducing the CO 2 content in the interior in an energy saving, since Indoor heat or cold is not released through an air exchange with outside air.
- the window does not have to be opened to allow outside air into the interior.
- a bioreactor which is arranged on and / or in the housing in such a way that the air stream flowing through the air cleaner flows through it, and which contains at least one living being which is designed to at least contain CO 2 contained in the air stream by means of photosynthesis partially convert to O 2 .
- the air cleaner according to the invention is therefore able to regulate the factor C0 2 content of the indoor air so that a person feels comfortable in an interior.
- the CO 2 contained in the indoor air is also not given to the outside air, so that no pipeline has to be laid there. Filtering CO 2 from the indoor air by means of the air cleaner according to the invention therefore does not require a connection to the outside air, such as a discharge from the interior.
- a person is provided with a perfect room climate in the interior, in particular a 0 2 content in the interior air being increased and the C0 2 content in the interior air being reduced. No dangerous and / or toxic substances are used and no such substances are created.
- the CO 2 is not stored in a storage medium from which it has to be released again.
- the at least one filter is preferably suitable for filtering air pollutants from the air flowing through it.
- Air pollutants are preferably coarse dust, fine dust, viruses,
- the at least one filter can be an electrostatic filter and / or an air washer.

- oxygenic photosynthesis one or more light-absorbing dyes such as chlorophyll are used to generate high-energy organic compounds such as carbohydrates, in particular glucose, from low-energy inorganic substances such as CO 2 and water, O 2 being formed.
- Plants and algae need light for photosynthesis. If there is no light, a respiration process begins, which damages the plant and algae.
- the basic idea of the bioreactor is therefore the reduction of CO 2 through the activity of the organism that is doing photosynthesis, which at least partially converts CO 2 to O 2 and biomass by means of photosynthesis.
