Abstract:

From the standpoint of offering reference for its optimal design, liquid-gas ejector is applied to lithium bromide absorption refrigerator in order to improve mass transfer efficiency. Many nozzles with different geometrical structures are adopted and experimental research is conducted to investigate the influence of physical dimension on performance of ejector. By comparison between convergent-divergent nozzle and convergent nozzle, the results show that, the reason for the influence on cooling capacity is different. With convergent-divergent nozzle, the cooling capacity increases with the decrease of throat diameter. With convergent nozzle, the tendency is on the contrary. With the same minimum cross area, the cooling capacity with convergent-divergent nozzle is better than that with convergent nozzle.
