Abstract (en)
[origin: US2011119952A1] A condensation dryer is provided that includes a drying chamber for items to be dried; a process-air circuit having a first fan; a heat pump in which a coolant circulates; an evaporator; a compressor; a condenser; a throttle; a temperature sensor to measure a temperature of the coolant; a cooler for the heat pump; and a controller. The condensation dryer further includes a comparator to compare the measured temperature of the coolant to a limit temperature that is stored in the controller and to switch on and operate the cooler during a period of time if the measured temperature of the coolant is equal to or greater than the limit temperature. The condensation dryer also includes an evaluator to evaluate a change in the measured temperature of the coolant during the period of time with regard to a non-permitted operating state of the condensation dryer.
