It indicates the rela tion between the performance and the design parameters of the screw compressor. Simultaneous ly, 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 com pressor products have been developed and mass manufactured to meet the requirement of refrige ration, aerodynamic and
