Abstract:

A transcritical CO2-[emim][Tf2N] absorption refrigeration system driven by double low-grade energy was built based on the principle of energy cascade utilization. In allusion to the characteristics of proposed system, the corresponding mathematical model was constructed. The influence regulation of key parameters to system performance was analyzed. The results showed that under given conditions compared with traditional absorption refrigeration system using the same refrigeration working pairs, the highest coefficient of performance (COP) of proposed system could be increased by 50%.
