Abstract
A liquid-injected compressor device for avoiding condensation of moisture in the outlet of a compressor is disclosed. The device comprises a control valve which is actuated in opposite directions by two sensors. One of the sensors senses the inlet temperature of the compressor and the other the outlet temperature. A constant temperature difference is maintained between the inlet and outlet of the compressor.
Claims8
A liquid-injected compressor device for avoiding condensation in the outlet of the compressor, comprising a compressor (1) provided with a first inlet (3) for working medium, a second inlet (4) for injection of liquid for cooling the working medium and an outlet (5) for compressed working medium, a liquid separator (7) connected to said outlet (5) and a liquid cooler (8) connected to said liquid separator (7) and to said second inlet (4) characterized by a control valve unit (9 or 71,72,73) provided with two sensors (10,11) for regulation of said cooling, whereby one of the sensors (10) is arranged for sensing the condition of the working medium at said first inlet (3) and the other sensor (11) is arranged for sensing a condition which stands in a predetermined relation to the condition of the compressed working medium at said outlet (5) and that said sensors (10,11) are arranged to actuate the control valve unit (9 or 71,72,73) in opposite directions.
