摘要
Abstract
This paper introduces the common refrigerants in refrigeration system,according to the comparison of ODP\GWP and so on,combined with the requirements of Montreal Convention and Classification Society Code,the long-term effective refrigerant is finally determined as carbon dioxide refrigerant;it further introduces the process principle of carbon dioxide refrigeration unit,and carries out the simulation design of supercritical carbon dioxide process with an expander based on the existing supercritical carbon dioxide process design,and finally reduces energy consumption of 67kW compared with the traditional carbon dioxide system.Finally,the supercritical carbon dioxide system with expander reduces energy consumption by 67 kW compared with the traditional carbon dioxide system,the COP of the refrigeration system increases from 1.13 to 2.13,and the power consumption of the refrigeration system is reduced by about 60％.关键词
