摘　　要：蒸汽压缩式制冷系统排气温度高,一般可用于制取生活用水。但不同的制冷系统排气温度区别很大,采用传统制冷剂的单级压缩很难制取高温热水。二氧化碳跨临界制冷系统相比传统制冷系统排气温度高,可用于屠宰场等需要高温热水的特殊场所。目前国内还没有屠宰场采用二氧化碳跨临界冷热联产的相关案例,本文通过相关选型模拟对某地区屠宰场进行改型,通过经济性分析,验证其可行性。The steam compression refrigeration system has a high exhaust temperature and can generally be used to produce domestic water.However,the exhaust temperatures of different refrigeration systems vary greatly,and it is dfficult to produce high-temperature hot water by single-stage compression of traditional refrigerants.Compared with the traditional refrigeration system,the carbon dioxide fast transcritical refrigeration system has a higher exhaust temperature and can be used in slaughterhouses and other special places requiring high temperature hot water.At present,there is no relevant case of carbon dioxide transcritical cogeneration of cold and heat in slaughterhouses in China.In this paper,the slaughterhouses in a certain area are modified through relevant model selection simulation,and its feasibility is verified through economic analysis.
