The water-lithium bromide-lithium nitrate absorption refrigeration cycle is compared with the traditional water-lithium bromide system. The effect of temperature, which is generating temperature or condensing temperature or evaporating temperature, on system performance is analyzed. Moreover the double-effect absorption refrigeration system is also investigated. The results show that the COP of the water-lithium bromide-lithium nitrate absorption refrigeration system has been enhanced. And the other thermodynamics parameters are also improved. Especially for the double-effect absorption system, the COP has been increased by 30%,and then the f has been reduced by 12%. Thus, the water-lithium bromide-lithium nitrate absorption system has better performance than the system of water-lithium bromide.
