Abstract

Ein Wäschetrockner ist mit einem Wärmepumpenkreislauf ausgestattet, um die Prozessluft zu kühlen und zu heizen. Im Wärmepumpenkreislauf ist ein Zusatzwärmetauscher (4) zwischen dem Kondensator (3) und dem Drosselorgan (5) angeordnet. An dieser Stelle ist die Temperatur relativ hoch, was die Effizienz des Zusatzwärmetauschers (4) verbessert. Zudem wird durch den Zusatzwärmetauscher (4) das Temperaturgefälle zwischen Verdampfer (6) und Kondensator (3) erhöht, was es erlaubt, der Prozessluft mehr Wasser zu entziehen.

Figure imgaf001
A tumble dryer is equipped with a heat pump cycle to cool and heat the process air. In the heat pump cycle, an additional heat exchanger (4) between the condenser (3) and the throttle body (5) is arranged. At this point, the temperature is relatively high, which improves the efficiency of the additional heat exchanger (4). In addition, the temperature gradient between evaporator (6) and condenser (3) is increased by the additional heat exchanger (4), which allows to extract more water from the process air.
