| Abstract: | According to the low performance of the refrigeration system, the principle of Einstein cycle refrigeration
system was explained, and the energy saving by analyzing and retrofitting the present heat exchanger network of the
system was analyzed by using the pinch technology. Problem table method was used to determine the pinch point
position, and the heat load of each heat exchanger was calculated. The results show that, the heat and cold input of the
system is reduced by 12. 5% and 48. 1% respectively , also the CCOP increased by 14. 3% after optimized. It is obviously
effective to improve the performance of Einstein cycle refrigeration system. |
