Abstract:
1. A ventilation and air conditioning system with an air purification apparatus, comprising: a channel enclosure defining an air duct of the ventilation and air conditioning system through which air to be purified flows in an air-flow direction; an air filter arranged in the air duct or in a filter wall for dust separation; and a dust agglomerator arranged in the air duct and connected upstream of the air filter or the filter wall, wherein the dust agglomerator comprises a number of wire electrodes and sheet metal plates spaced from one another, in which the electrodes and the sheet metal plates are each alternately arranged and a direct current (DC) voltage field is able to be generated with the electrodes, and wherein the dust agglomerator is situated in the air duct transverse to the air-flow direction and arranged parallel to the air filter or filter wall, wherein the dust agglomerator is designed as a plug-in module and is fixed transversely to the channel enclosure, wherein a direct current (DC) rectifier is able to be employed to generate the direct current voltage field, wherein the DC rectifier is integrated directly into a frame of the dust agglomerator, and wherein the dust agglomerator in the form of a plug-in module is fastened directly to a frame of the filter or to the filter and is able to be assembled into the channel enclosure as a common unit.
