Abstract

The process is for air drying processes in which the moisture removal from a drying chamber (10) takes place by means of exhaust air. Dry substitute air (Gk) is fed into the drying chamber (10) and a portion of the heat energy of the exhaust air (Gp) is transferred by means of a heat pump system (106) to the substitute air (Gk). The substitute air is heated in at least two successive phases, the substitute air (Gk) being heated in a first phase in a heat exchanger and/or a water radiator, the heat energy of which is taken from the exhaust air (Gp), and the substitute air (Gk) being heated in the second phase in a condenser of the heat pump system (106) or a plurality of successive condensers (15a, 15b, 15c) of a multi-circuit heat pump. An evaporator, or a plurality of evaporators (12a, 12b, 12c) of a multi-circuit heat pump, is arranged in the heat pump system (106) so that they take heat energy from the exhaust air (Gp). In the first phase, the substitute air (Gk) is heated in a heat exchanger (1) by means of exhaust air (Gp). The evaporator of the heat pump system, or the evaporators (12a, 12b, 12c) of the multi-circuit heat pump system (105), is/are downstream of the exhaust air-substitute air heat exchanger, as seen in the flow direction of the exhaust air (Gp), or alternatively the substitute air (Gk) is heated in the first phase in a water radiator (9), the heating medium of which is heated by exhaust air (Gp) in a water heat exchanger (13), which is situated downstream of the evaporator of the heat pump system, or downstream of the evaporators (12a, 12b, 12c) of the multi-circuit heat pump system (106), as seen in the flow direction of the exhaust air. <IMAGE>
