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 compressor (17) is located in the flow (21) of process air, between the evaporator (15) and the condenser (19). Thereby, heat dissipated from the compressor is used to pre-heat the process air flow before entering the condenser (19).
