Condensation clothes dryer with a heat pump and auxiliary resistance heater |
(57) The invention concerns a condensation clothes dryer with a heat pump and a closed
process air circuit that proceeds from a dryer drum and returns to it via an evaporator,
blower and a condenser as well as an auxiliary resistance heater. The heat pump circuit
for the cold-start, heating and operating phase is automatically adapted without program-controlled
changes in the heat output and without overload protection as follows: The auxiliary
resistance heater consists of one or more semiconductor resistors that heat the coolant
for the condenser of the heat pump circuit.
