Thermodynamic analysis of a transcritical R744 vapour-compression/ejection hybrid refrigeration cycle.

Author(s) : LIU J. P., CHEN J. P., CHEN Z. J.

Summary

In the cycle, an ejector is used instead of a throttling valve to recover some of the kinetic energy of the expansion process. Through the action of the ejector, the compressor suction pressure is higher than it would have been in a standard cycle. Thus, the compressor does less work, resulting in energy saving. The theoretical analysis and simulation of this cycle have been carried out and the results indicate that the new cycle can improve the transcritical CO2 cycle's performance effectively.
