Definitions

  • the object of the present invention is implementing a method of operating a laundry drying machine, such as a heat pump laundry dryer or a heat pump washing machine having drying function, in order to carry out a laundry treatment process on a laundry load comprising a drying cycle.
  • a laundry drying machine such as a heat pump laundry dryer or a heat pump washing machine having drying function
  • the first level and the third level may be substantially equal to each other, and the second level and the fourth level may be substantially equal to each other.
  • the compressor is respectively of a variable speed type or of a fixed speed type.
  • duty cycle time compressor 17 on/ cycle time * 100 % .
  • said third path has a third sequence type with series of variable duty cycles.
  • the third lower energy level and third upper energy level are lower than the second lower energy level and the second upper energy level respectively.
  • the third lower energy level A131 corresponds to the first lower energy level A111.
  • the third upper energy level A132 corresponds to the first upper energy level A112.
  • a fourth phase P104 (for example, a cooling phase) is selected based on the said second laundry moisture level H102 selected according to said third drying phase P103.
  • End of the drying process occurs when the at least one of the above-listed end conditions (e.g. laundry load is below a predetermined moisture level or process air leaving the drum is below a predetermined temperature imposed).
  • An optional phase may also be selected for anti-crease or anti-wrinkles.
