摘　　要：建立了太阳能喷射—压缩复合蓄冷系统热力学计算模型,选取HFC134a作为制冷工质,计算结果表明:蒸发温度在-15℃～-5℃,冷凝温度为35℃和40℃时,太阳能喷射—压缩制冷系统的EER要优于单独喷射和单独电压缩系统;太阳能喷射—压缩制冷系统的EER值随中间冷却温度的升高而先升高后降低,并且随着冷凝温度的升高,其最优温度也会升高.The thermodynamics model is established to analyse the solar ejection-compression refrigeration system which used HFC134a as working fluid.It is found that the EER of solar ejection-compression refrigeration system is superior to the pure ejector refrigeration system or compressor refrigeration system.when evaporation temperature is at-5℃～-15℃ and condensation temperature is at 35℃ and 40℃ respectively,the EER of the solar ejector-compressor refrigeration system increases first and then decreases with intermediate cooling temperature,and it will increase with the condensation temperature increasing.
