Abstract

The disclosure relates to a method for operating a ventilation system with a mixing chamber into which air is supplied via a first supply duct and via at least one further supply duct. Air is removed from the mixing chamber by a removal duct. The supply of air—volume control—into the mixing chamber from the supply ducts is controlled in each case via flaps with a plurality of flap leaves and/or a plurality of flap units each having a plurality of intercoupled flap leaves. According to the disclosure, the flap leaves and/or the flap units are activated individually, and an individual opening position of the respective flap leaves or of the flap units with the flap leaves is made possible.

First claim

The invention claimed is:

1. A method for operating a ventilation system comprising:
supplying first air into a mixing chamber via a first supplying duct by controlling a first plurality of flaps having at least one of (i) a first plurality of flap leaves and (ii) a first plurality of flap units, each of the first plurality of flap units having a first plurality of intercoupled flap leaves, by individually activating at least one of the first plurality of flaps such that each of the first plurality of flaps has a respective individual opening position;
supplying second air into the mixing chamber via a second supplying duct by controlling a second plurality of flaps having at least one of (i) a second plurality of flap leaves and (ii) a second plurality of flap units, each of the second plurality of flap units having a second plurality of intercoupled flap leaves, by individually activating at least one of the second plurality of flaps such that each of the second plurality of flaps has a respective individual opening position;
mixing the first air with the second air using different flow resistances based on differences between at least one of (i) physical characteristic values of the first air and quality values of the first air and (ii) corresponding physical characteristic values of the second air and quality values of the second air, wherein:
increasing the flow resistance includes orienting at least one of the first plurality of flaps and the second plurality of flaps such that the first air supplied from the first supplying duct and the second air supplied from the second supplying duct are guided in a direction toward each relative to a removing duct; and
reducing the flow resistance includes orienting at least one of the first plurality of flaps and the second plurality of flaps such that the first air supplied from the first supplying duct and the second air supplied from the second supplying duct are guided in a direction toward the removing duct relative to each other; and

removing the mixed first air and second air from the mixing chamber via a removing duct.

2. The method as claimed in claim 1 , wherein the mixing includes:
increasing the flow resistance in response to the at least one of the physical characteristic values of the first air and the quality values of the first air being different from the corresponding physical characteristic values of the second air and quality values of the second air.

3. The method as claimed in claim 2 , further comprising:
determining the at least one of the physical characteristic values of the air in the supplying ducts and the quality of the air in the supplying ducts with sensors.

4. The method as claimed in claim 2 , wherein the mixing includes:
reducing the flow resistance in response to at least one of physical characteristic values the first air and the quality values of the first air being approximately identical to the corresponding physical characteristic values of the second air and quality values of the second air.

5. The method as claimed in claim 2 , further comprising:
selecting a portion of the at least one of the first plurality of flaps and the second plurality of flaps to open with reference to a quantity of air required from at least one of the first supplying duct and the second supplying duct.

6. The method as claimed in claim 5 , further comprising:
opening individual flaps at different opening angles.

7. The method as claimed in claim 6 , further comprising:
prioritizing a sequenced activation of the individual flaps with reference to the different opening angles of the individual flaps.

8. The method as claimed in claim 2 , further comprising:
orienting the flaps to so as to reduce noise production in the mixing chamber.

9. The method as claimed in claim 2 , wherein the at least one of the physical characteristic values and the quality values of the first and second air includes at least one of temperature, pressure, density, moisture, oxygen content, CO 2 content, and pollutant content of the air being different in the first supplying duct and the at least one further supplying duct.

10. A method for operating a ventilation system comprising:
supplying first air into a mixing chamber via a first supplying duct and supplying second air into the mixing chamber via a second supplying duct;
removing the first and second air from the mixing chamber via a removing duct;
controlling the supply of first air into the mixing chamber from the first supplying duct via at least one first flap having at least one of (i) at least one first flap leaf and (ii) at least one first flap unit, each first flap unit having a first plurality of interconnected flap leaves;
controlling the supply of second air into the mixing chamber from the second supplying duct via at least one second flap having at least one of (i) at least one second flap leaf and (ii) at least one second flap unit, each second flap unit having a second plurality of interconnected flap leaves; and
mixing the first air with the second air using different flow resistances based on differences between at least one of physical characteristic values of the first air and quality values of the first air and corresponding physical characteristic values of the second air and quality values of the second air, wherein:
increasing the flow resistance includes orienting each flap such that the first air supplied from the first supplying duct and the second air supplied from the second supplying duct are guided in a direction toward each other relative to the removing duct; and
decreasing the flow resistance includes orienting each flap such that the first air supplied from the first supplying duct and the second air supplied from the second supplying duct are guided in a direction toward the removing duct relative to each other.

11. The method as claimed in claim 10 , wherein the mixing includes:
increasing the flow resistance in response to at least one of physical characteristic values of the first air and quality values of the first air being different from corresponding physical characteristic values of the second air and quality values of the second air.

12. The method as claimed in claim 10 , wherein the mixing includes:
decreasing the flow resistance in response to at least one of physical characteristic values of the air and quality values the first air being approximately identical to the corresponding physical characteristic values of the second air.

13. The method as claimed in claim 10 , wherein the at least one of the physical characteristic values and the quality values of the first and second air includes at least one of temperature, pressure, density, moisture, oxygen content, CO 2 content, and pollutant content of the air being different in the first supplying duct and the at least one further supplying duct.
