The present invention relates to tumble dryer with at least one heat pump system. The tumble dryer comprises an air stream circuit (10) including at least one drum (12) for receiving laundry to be dried, at least one refrigerant circuit (14) including at least one compressor (16) with a variable rotation speed, a first heat exchanger (18) for a thermal coupling between the air stream circuit (10) and the refrigerant circuit (14) and a second heat exchanger (20) for a further thermal coupling between the air stream circuit (10) and the refrigerant circuit (14). The tumble dryer comprises further a control unit (22) for controlling the rotation speed of the compressor (16) and at least one sensor for detecting at least one physical parameter (TDI, TDO; TEI, TEO; TF; Z; RH) as function of the time of the air stream, the refrigerant ad/or the laundry. A central processing unit is provided, which is arranged to evaluate the time development of the physical parameter (TDI, TDO, TEI, TEO; TF; Z; RH) and which reduces the rotation speed of the compressor (16) according to the evaluation of the time development of the physical parameter (TDI, TDO, TEI, TEO; TF; Z; RH). Further, the present invention relates to a corresponding method for controlling a heat pump system for a tumble dryer.
