FIELD: machine building.
SUBSTANCE: invention relates to compressor-building industry and can be used in compressors with liquid cooling. Compressor device comprises a compressor element 2 with compression Chamber, with one inlet 8 of cooling agent and gas output 4. Separating tank 5 for separation of gas from cooling agent is connected to gas output 4. Cooling circuit with cooling device 10 passes between separation tank 5 and inlet 8 of cooling agent and is equipped with control unit for controlling temperature of cooling agent flow supplied to compressor element 2. Control unit comprises first and second auxiliary regulators 25, 26 with different controlled parameters. Control units comprise switching 37, 38 means to actuate one of two auxiliary 25, 26 regulators in activated state, and other of two auxiliary 25, 26 regulators in deactivated state.
EFFECT: flexibility of control, possibility to work with optimum power consumption, higher reliability.
