Experimental analysis of a hybrid ejector-based air-conditioning system using R134a

This paper describes the experimental study of a hybrid ejector-based air-conditioning system using R134a. The proposed system can be operated under different modes. A series of experiments have been conducted to investigate the effect of the generating, condensing and evaporating pressure on the system performance and entrainment ratio. The results indicate that: the performance of hybrid system is sensitive to the three pressures; the coefficient of performance (COP) of hybrid mode is around 35% higher than that of general mode.
