Abstract

Die Erfindung betrifft eine Vorrichtung (10) und ein Verfahren zum Trocknen eines Werkstückes, wie beispielsweise einer Fahrzeugkarosserie nach dem Lackieren. Dabei weist die Vorrichtung (10) mindestens zwei Aufheizzonen (20, 30) auf. In der Aufheizzone (30) mit höherem Temperaturbedarf wird die Abluft abgezogen und der Aufheizzone (20) mit dem geringeren Temperaturbedarf als Zuluft zugeführt. Da die Abluft der wärmeren Aufheizzone (30) noch immer eine recht hohe Temperatur aufweist, kann in der Aufheizzone (20) mit der geringeren Temperatur ein Wärmetauscher entfallen. Dadurch können Bauraum, Energie und Kosten eingespart werden.

The invention relates to a device (10) and a method for drying a workpiece, such as a vehicle body, after painting. The device (10) has at least two heating zones (20, 30). In the heating zone (30) with a higher temperature requirement, the exhaust air is drawn off and fed to the heating zone (20) with the lower temperature requirement as supply air. Since the exhaust air from the warmer heating zone (30) still has a very high temperature, a heat exchanger can be omitted in the heating zone (20) with the lower temperature. This saves installation space, energy and costs.
