Description
Technical field [0001] The present invention relates to the field of air conditioning techniques, and more particularly to a screw compressor system, control method, and air conditioning that can accurately regulate load. Background technique [0002] With the development of air conditioning technology, the twin screw compressor has been widely used in commercial air conditioning. The volumetric flow adjustment method of the compressor is to flow into the oil piston in the oil passage through the oil in the oil tank, and the moving piston movement in the piston chamber is pushed by the oil pressure, and the movement of the oil piston is moved through the sliding valve. By adjusting the position of the slider, the volumetric flow is adjusted. However, existing twin-screw compressors cannot accurately reduce the position and force of the controlled valve, resulting in slow change of hydraulic fluctuations or disclosure, and the load fluctuation, etc., which seriously affects the st...
