Since the efficiency of traditional absorption refrigeration system driven by low-grade energy is low
a new CO2-[emim][Tf2N] absorption refrigeration cycle driven by double low-grade energy is introduced based on cascaded utilization energy. Experimental equipment is built to evaluate the performance of the new refrigeration system. Experimental results at constant flow rates indicate that COP and cooling capacity of the new system increase with the increase of heat ratio between the two generators
decrease with the increase of cooling water and pressure in high pressure generator. The new system gives a higher value of refrigeration capacity and a higher value of COP. Compared with the traditional absorption refrigeration system
