Résumé

A hybrid vapor compression refrigeration (HVCR) system, which combines a vapor com- pression refrigeration (VCR) system and an ejector refrigeration (ER) system, was developed. The waste heat energy from the gas cooler in the VCR system is applied as driven source towards ER system. Thermodynamic investigations on the performance of the HVCR system, using CO 2 as a refrigerant, are performed with energetic and exergetic methods, and the comparative analy- ses with the VCR system are conducted. Comprehensive effects of key operating parameters on the system performance are also studied. The results indicate that for the same cooling capacity, the coefficient of performance (COP) of the HVCR system shows 25% higher COP and the total mechanical power consumption is reduced by 20% than that of conventional VCR system, respectively. The performance characteristics of the proposed cycle show its application potential in cooling and air-conditioning.
