Abstract
The present disclosure relates to a tumble dryer 1 with a rotatable drum 11 and a heat pump for drying process air that enters the drum, the heat pump comprising a condenser 19, a compressor 17, and an evaporator 15. In order to improve energy efficiency, the rotatable drum comprises a circular rear wall with air inlet openings and a radial cylindrical wall with air outlet openings, the compressor 17 is adapted to be run by an inverter 29, allowing the compressor output to be varied, and the expansion 16 is controllable. This allows the heat pump arrangement to be controlled to an optimum heat pump cycle envelope.
