ABSTRACT:
The invention relates to a method for regulating a compressor installation with at least one compressor element (6) driven by a motor and, in the pressure conduit (11) thereof, a dryer (2) of the type comprising a pressure vessel (24) with a drying zone (3) and a regeneration zone (4), and a rotor (25) continuously rotated in this pressure vessel (24) by a motor (33), which rotor is filled with a regenerable drying agent. A portion of the compressed air is supplied, by means of a branch (15), to the regeneration zone (4) and, after cooling down and separation of the condensed water, is fed back to the pressure conduit (11). The speed of both motors (9, 33) is regulated by a regulation device (13) in function of the pressure in the pressure conduit (11).
