Abstract:
1. A method for operating a condenser dryer with a drying chamber for retaining objects to be dried, a process air circuit having a heating element for heating the process air in the drying chamber, and a heat pump circuit for heating process air with the heat pump circuit including an evaporator, a compressor, and a condenser, and a sensor arrangement for determining a level of humidity in the objects to be dried, the method comprising the steps of: determining humidity within the drying chamber using the sensor arrangement; in the event that the humidity is determined to be equal to a predetermined humidity value of between about 0% to about 12%, heating the process air using the heat pump circuit; and in the event the humidity is determined to be less than the predetermined humidity value, activating the heating element to heat the process air in the drying chamber to a predetermined temperature value of at least 70° C. for a predetermined time period.
