摘　　要：冰箱作为家庭常用且持续运行的家用电器之一,在居民生活用电占有很大的比例。在中国2030年实现碳达峰,2060年实现碳中和背景下,冰箱节能具有重要的意义。同时,人们对于食品保鲜的要求也越来越高,冷冻储藏温度越来越低。为满足更加低温、更大冷量、更低电量的需求,对比了R600a、R290及其混合制冷剂的冷量、消耗功率、COP,发现在R600a中引入合适比例的R290可以优化系统的整体COP,增大冷量,更好地满足用户需求。Refrigerator, as one of the household appliances used in the family and running continuously, its power consumption occupies a large proportion of the electricity consumption in the residents’ daily life. In the context of China achieving carbon peak by 2030 and carbon neutral by 2060, the energy saving of refrigerators is of great significance. At the same time, people have higher and higher requirements for food preservation,and the frozen storage temperature is getting lower and lower. In order to meet the demand of lower temperature, greater cooling capacity and lower power, compared the cooling capacity, power consumption and COP of R600 a, R290 and their mixture, and found that the introduction of appropriate R290 into R600 a can optimize the overall COP of the system, increase the cooling capacity and meet better user requirements.
