Abstract

The present invention relates to a laundry dryer with a heat pump system. The heat pump system comprises a closed refrigerant circuit (10) for a refrigerant and a drying air circuit (12) for drying air. The refrigerant circuit (10) includes a compressor (14) and lamination means (18). The air stream circuit (12) includes a laundry drum (52) and at least one fan (52). The refrigerant circuit (10) and the air stream circuit (12) are thermally coupled by a first heat exchanger (16) for heating up the air stream and cooling down the refrigerant and a second heat exchanger for cooling down the air stream and heating up the refrigerant (20). The refrigerant circuit (10) comprises a low pressure side (24) between the outlet of the lamination means (18) and the inlet of the compressor (14). The refrigerant circuit (10) comprises a high pressure side (26) between the outlet of the compressor (14) and the inlet of the lamination means (18). The low pressure side (24) and the high pressure side (26) are thermally coupled by at least one internal heat exchanger (22; 40, 42). The refrigerant circuit (10) includes at least one by-pass line (28; 38) for bypassing at least a part of the low pressure side (24) and/or high pressure side (26) of the internal heat exchanger (22; 40, 42),
