摘要：A compressor includes a casing, a screw rotor, a slide member with at least oneeconomizer port, and a control unit controlling a position of the slide member along theaxis of the screw rotor to position the at least one economizer port based on the
rotating speed of the screw rotor to advance the timing of opening of the at least oneeconomizer port. The controller controls the position of the slide member along the axissuch that the slide member moves upstream toward a suction side of the compressorwhen the rotating speed of the screw rotor increases, and downstream toward a
discharge side of the compressor when the rotating speed of the screw rotor decreases.A refrigerating apparatus includes the compressor, a condenser, a heat exchanger, anexpansion unit, and an evaporator, sequentially connected, and has an economizer line.
