In the degreasing device, the liquid solvent (3') is evaporated in a liquid compartment (1') and the solvent vapour (6') is condensed on a cooling coil (7'). To save energy, the heat carried off to the cooling coil (7') is again supplied to the liquid compartment (1') via a heat pump system. To this end, in the exemplary embodiment illustrated, a part of the solvent condensed on the cooling coil (7') is expanded via an expansion valve (14), evaporated in the cooling coil (7'), compressed in a compressor (10) and subsequently condensed in the liquid compartment (1'), yielding heat. <IMAGE> |
