Abstract

The invention relates to a method for operating a laundry drying apparatus, in particular a laundry dryer or a washer-dryer, during a drying program, and a laundry drying apparatus. The laundry drying apparatus (2) comprises: a drum (18) adapted to receive laundry (19) for drying the laundry using drying air; a drying air fan (8) adapted to convey drying air through the drum (18); a motor (46) adapted to drive the drying air fan (8); a heat-pump system (4) comprising a first heat exchanger (10) adapted to heat the drying air, a second heat exchanger (12) adapted to cool the drying air for humidity condensation, and a compressor (16) adapted to circulate refrigerant through the first and second heat exchangers (10, 12); and a laundry load indicating or detecting unit adapted to determine or estimate a laundry amount of laundry loaded into the drum (18), wherein the compressor (16) is a variable speed and/or variable power compressor. The method comprises: starting a drying program for drying the laundry received in the drum (18); operating the compressor (16) at an initial compressor output; the laundry load indicating or detecting unit (52) determining or estimating a laundry amount at least once during the drying program; setting a threshold value in dependency of the laundry amount; monitoring an operation parameter of the laundry drying apparatus; and operating the compressor (16) at a reduced compressor output if the monitored operation parameter reaches or exceeds the set threshold value.
