Abstract
An apparatus for purifying air, in particular for ventilation and air-conditioning systems, has an air filter (11), which is inserted in an air channel (10) or in a filter wall for collecting dust. A dust agglomerator (12) with a DC voltage field is connected directly upstream of the air filter (11). In conventional filters, the efficiency is increased to such an extent that the dust throughput can be approximately halved. In addition, the initial efficiency is only insignificantly reduced during the operating time.
Claims16
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.
