In order to explore the performance of R134a / DMF absorption refrigeration system, a model of R134a/DMF absorption refrigeration system was conducted based on Aspen Plus software. The cooling capacity of the system 150kW. The effects of reflux ratio, bottom temperature and refrigerant (R134a) concentration on the system were simulated and analyzed. The results showed that, the reasonable range of reflux ratio and scope of bleed is 0.5∼0.7. The system COP is the best when the mass fraction of R134a, the generating temperature and absorption temperature is respectively 56 %, 131°C and 28 °C.
