Compressor device comprising an oil-injected compressor element () with an outlet () connected via an outlet line () to an oil separator () which is connected via an injection pipe () to the compressor element (), wherein controllable cooling means () for the oil are provided, the compressor device () being provided with a control unit () and thereto connected measuring means () for controlling the cooling means () to control a temperature (T_uit_afsch) downstream of the oil separator (), the measuring means () including means () for determining a temperature (T_uit) at the outlet () and a temperature sensor () for determining the temperature (T_uit_afsch) downstream of the oil separator (), the control unit () including a controller () for controlling the cooling means () on the basis of signals from said measuring means () and on the basis of a dew point.

Compressor device and method for controlling such compressor device

Compressor system provided with a compressor device with at least one compressor element with an outlet for compressed gas, an outlet line connected to this compressor device for the compressed gas, and a dryer connected to said outlet line of the type using a drying agent or desiccant for drying the compressed gas from the compressor system. The dryer is provided with a drying section and a regeneration section with an inlet and an outlet for a regeneration gas. A regeneration line is connected to the inlet of the regeneration section. The regeneration line includes a first heat exchanger for heating the regeneration gas. A secondary section of said first heat exchanger forms a condenser of a heat pump. An evaporator of the heat pump is provided in the compressor system.
