Numerical simulation and experimental comparison of refrigeration and air conditioning scroll compressors: application to transcritical carbon dioxide cycles.

Author(s) : ROVIRA J., RIGOLA J., OLIVA A., et al.

Summary

A numerical simulation model of scroll compressors has been developed to obtain temperature, pressure, and mass flow rate pattern evolution, solving continuity, momentum and energy equations. Chamber volumes, areas and leakages calculus have been programmed following (Halm, 1997) formulation. Chen's thermal resistances have been introduced in the model for the whole compressor thermal treatment. Fluid properties are calculated from (REFPROP, 1998) database for each volume. To validate the numerical model presented, several experimental results of (Halm, 1997) and (Park, 2002) have been compared, considering R-22 as a working fluid. The general comparisons obtained have shown a reasonable good agreement. A first illustrative CO2 results are presented and compared against R-22 standard compressor. The results show the possibilities of CO2 for refrigeration and air conditioning applications. The influence of some aspects has also been studied.
