Abstract (en)
[origin: EP3425109A1] The present invention refers to a mthod of operating a laundry drying machine (10), 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 (L) comprising a drying cycle, wherein the laundry drying machine (10) comprises: a control unit (11) controlling the operation of the laundry drying machine (10), a laundry treatment chamber (12) for treating laundry using process air (A), a process air circuit (13) for circulating the process air (A), a heat pump system (14 ) having a refrigerant loop (15), in which the refrigerant fluid (R) is circulated through a first and a second heat exchanger (16a,16b) in thermal communication with the process air (A), a compressor (17) for circulating the refrigerant fluid (R) through the refrigerant loop (15), and wherein the method comprises the following steps: - driving the compressor (17) by means of the control unit (11) according to a first driving sequence in a first portion (Pi) of the drying cycle; - driving the compressor (17) by means of the control unit (11) according to a second driving sequence in a second portion (P2) of the drying cycle different from the first portion; characterized in thatthe second driving sequence provides for driving the compressor (17) intermittently between a lower level of energy and an upper level of energy wherein the lower and upper level of energy and a condition for ending the second driving sequence are defined depending on one or more parameters of the following first list: - laundry load (L) amount; - moisture content of laundry load (L); - temperature of laundry load (L); - temperature of the process air (A); - temperature and/or humidity of the environment where the laundry drying machine (10) is placed; - laundry treatment program selected by a user; - laundry treatment process or drying process time; - a preset value of energy consumption.
