Summary

The Conical Rotary Compressor (CRC) is a versatile Positive Displacement Machine (PDM) consisting of one inner conical screw rotor rotating inside an outer conical screw rotor, which has various applications in heat pump, refrigeration, compression and vacuum fields. Quasi-steady modelling has been successfully implemented on piston compressors, scroll compressors and twin-screw compressors to optimize performance and compressor design. This study is intended to develop the mathematical model to simulate the quasi-steady performance based on the geometrical and working characteristics of conical rotary compressor. The control volume of the CRC is firstly calculated. Secondly, based on the assumptions for the analysis of the control volume, the conservation equations of mass and energy, state equation with considering of leakage are solved using adaptive Runge-Kutta method. Finally, the volume flow rate and specific power of air conical rotary compressor are calculated and compared with experimental results to improve and validate the model. Based on this study, the working performance, rotor profile, size and cost of conical rotary compressors can be optimized at the design stage.
