ShareSummary
This paper presents an enhanced ejector refrigeration cycle(EERC) by introducing a flash tank economizer and an auxiliary ejector to improve the performance of a conventional ejector refrigeration cycle (CERC). Thermodynamic performances of the EERC using R134a are evaluated in detail and compared with those of the CERC using the first law of thermodynamic. Results show that there is an optimal inlet temperature of flash tank economizer in EERC. Compared with CERC, the maximum COP and the cooling capacity of EERC with R134a increase by 10.7% and 10.6%, respectively. Furthermore, the EERC shows better performances under higher evaporating temperature.
