METHOD FOR CONTROLLING A LAUNDRY DRYING MACHINE WITH HEAT PUMP SYSTEM AND LAUNDRY DRYING MACHINE CONTROLLED BY SUCH METHOD

A laundry drying machine with a heat pump system comprises a process air circuit including a rotating drum, a blower and a heater, a refrigerant circuit including a compressor, a condenser, an expansion device, an evaporator, the condenser and evaporator being in heat exchange relationship with the process air circuit, an auxiliary condenser cooled by an air flow driven by a fan, and at least two temperature sensors placed in the process air circuit and/or in the refrigerant circuit. A method for controlling the laundry drying machine includes receiving an input indicating a desired behavior of the laundry drying machine selected from the group consisting of optimized use of energy, overall drying time and fabric care, and controlling components of the machine according to signals from the two temperature sensors and according to the desired behavior.
