Abstract (en)
The invention relates to a laundry treatment apparatus (2), in particular a heat pump dryer or washing machine having dryer function, and to a method for operating the apparatus, wherein the apparatus (2) comprises a heat pump system (4) and a laundry treatment chamber (18) for treating laundry using process air (A), and wherein the heat pump system comprises a first heat exchanger (10) for heating a refrigerant fluid (R), a second heat exchanger (12) for cooling the refrigerant fluid (R), an expansion device (16), a refrigerant loop (6), in which the refrigerant fluid is circulated through the first and second heat exchangers and the expansion device, and a variable speed and/or variable power compressor (14) for circulating the refrigerant fluid (R) through the refrigerant loop (6), the method comprising the steps of detecting at least one temperature signal, selecting a predetermined speed and/or power profile for operating the compressor (14) in dependency of the at least one detected temperature signal, and starting to operate the compressor (14) in a laundry drying cycle by applying or executing the selected predetermined speed and/or power profile to the compressor (14) during the drying cycle in dependency of the at least one detected temperature signal.
