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.
Key words: Absorption refrigeration, experimental research, lithium bromide, nozzle, , ,
