- process air In a condensation dryer air (so-called process air) is passed through a fan via a heater in a wet laundry containing drum as a drying chamber. The hot air absorbs moisture from the laundry to be dried. After passage through the drum, the then moist process air is passed into a heat exchanger, which is usually preceded by a lint filter.

- WO 2008/107266 A1 and WO 2008/1 1961 1 A1 each disclose a tumble dryer with a heat pump.
- a heat pump in a tumble dryer is usually designed as a compact unit and arranged below the drum for the items to be dried.
- An electric heater for the process air is not available.
- DE 20 2006 014 718 U1 relates to a tumble dryer with a heat pump with CO 2 as the medium, in which a heat exchanger is used which has a plurality of heat exchange body and at least one in thermal contact with these arranged tube for the medium, wherein a heat conduction within each heat exchange body larger is as a heat conduction between the heat exchange bodies.
