Following the theoretical research on working process of screw compressors, the mathematical models for simulation of the thermodynamic performance and dynamic characteristics of the screw compressor are proposed, which are experimentally verified by means of recording the indicator diagrams （p-V diagrams） with a small pressure sensor embedded in the female rotor, the measurement of pressure pulsation in the discharge chamber and the forces acting on the rotors, and the visualization experiment on oil distribution in the compressor. It indicates the relation between the performance and the design parameters of the screw compressor. Simultaneously, the key technology for screw compressor is developed including profile design method, the cutter design, the soft package of SCCAD. Up to now, more than 50 models of twin screw compressor products have been developed and mass manufactured to meet the requirement of refrigeration, aerodynamic and petrochemical industry.
