Abstract (en)

[origin: WO2008031688A1] The invention relates to an apparatus (1) for drying items of laundry (2), comprising an essentially closed first channel system (3) for channelling a process-air stream (4) which acts on the items of laundry (2), in which first channel system (3) are arranged a treatment chamber (5) for receiving items of laundry (2), a first fan (6) for driving the process-air stream (4), a first cooling channel (7) of a heat exchanger (7, 8), and a second heating channel (9) of a heat pump (9, 10, 11), which second heating channel (9) is located, along the process-air stream (4), downstream of the first cooling channel (7), and also comprising an open, second channel system (12) for channelling a secondary-air stream (13), in which second channel system (12) are arranged a second fan (14) for driving the secondary-air stream (13), a first heating channel (8) of the heat exchanger (7, 8), and a second cooling channel (11) of the heat pump (9, 10, 11). The first channel system (3) additionally contains a heater (15) for heating the process-air stream (4), and the second cooling channel (11) is located, along the secondary-air stream (13), downstream of the first heating channel (8). The invention also relates to a process which is suitable for being carried out in such an apparatus (1).
