Abstract (en)

The invention relates to a machine (1) comprising a treating chamber (2) for drying humid articles (3) by process air at a pressure substantially equal to an ambient pressure, a process air guide (5) for guiding the process air through said treating chamber (2) in a first circuit substantially closed in itself, said process air guide (5) comprising a first blower (6) for driving the process air, a heater (10) for heating the process air and placed upstream of said treating chamber (2), and a cooler (8) for cooling the process air and placed downstream of said treating chamber (2), wherein said heater (10) and cooler (8) form a heat pump (8,10,12,13) comprising a compressor (12) for driving and compressing the refrigerant through said heat pump and an expander (13) for expanding the refrigerant in a refrigerant circuit (11) and an operating unit (14) for operating said heat pump. Said machine (1) is provided to be operable with superheating the refrigerant to between 6°C and 22°C. Further, the invention relates to a process for execution in such a machine (1).
