Abstract

Es ist bekannt, zum Trocknen eines Gegenstandes ein Gas, beispielsweise Luft zu erwärmen und dann über den Gegenstand zu blasen. Besitzt diese Luft eine hohe Aus­ gangsfeuchtigkeit, so muß sie stark erwärmt werden, um den gewünschten Trocknungseffekt rasch zu erzielen. Ist eine hohe Temperatur nicht zulässig, ergeben sich lange Trock­ nungszeiten. It is known to dry an object Gas, for example air to heat and then over the Blow object. This air has a high out moisture, so it must be heated to to achieve the desired drying effect quickly. Is a high temperature not permissible, long dry results times.

Für eine schnelle Trocknung bei mäßiger Temperaturer­ höhung wird erfindungsgemäß das Gas vor dem Erwärmen durch Abkühlen bis zum Taupunkt und Sammeln und Abführen der kondensierenden Flüssigkeit entfeuchtet. For quick drying at moderate temperatures According to the invention, the gas is increased before heating by cooling to the dew point and collecting and Dehumidification of the condensing liquid.

Nach Figur 1 weist ein Trockengerät einen ersten Wärmetauscher (13) zum Abkühlen der angesaugten Luft bis zum Taupunkt und einen zweiten Wärmetauscher (12) zum Erwärmen der so entfeuchteten Luft auf. Vorzugsweise sind die Wärmetauscher der Verdampfer bzw. Kondensator einer Wärmepumpe, die einen Kompressor (15) besitzt, der über umsteuerbare Rohrleitungen mit den Wärmetauschern ver­ bunden ist, so daß zum Abtauen von Eis die Funktion der Wärmetauscher umgekehrt werden kann. According to Figure 1, a drying device has a first Heat exchanger (13) for cooling the sucked air up to to the dew point and a second heat exchanger (12) to Warm up the dehumidified air. Are preferred the heat exchanger of the evaporator or condenser Heat pump, which has a compressor (15), which reversible pipes with the heat exchangers is bound, so that the function of the Heat exchanger can be reversed.
