A comprehensive model of scroll compressors. 1. Compression process modelling.

Author(s) : CHEN Y., HALM N. P., GROLL E. A., et al.

Summary

The governing mass and energy conservation differential equations were developed for each compressor chamber. Models for the refrigerant flow in the suction and discharge processes, radial and flank leakage, and heat transfer between the gas and scroll wraps were combined with the conservation equations. The state of the refrigerant changes with a period of angle, and thousands of steps are used to solve the governing differential equations during each period. It is assumed that in each step the compressor is in steady state. All these equations are solved simultaneously using a nonlinear equation solver.
