Abstract
The present disclosure relates to a tumble dryerwith a rotatable drumand a heat pump for drying process air that enters the drum, the heat pump comprising a condenser, a compressor, and an evaporator. 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 compressoris adapted to be run by an inverter, allowing the compressor output to be varied, and the expansionis controllable. This allows the heat pump arrangement to be controlled to an optimum heat pump cycle envelope.
