摘　　要：在商用制冷陈列柜的制冷系统中,氟利昂制冷剂应用广泛。但是,因氟利昂制冷剂对臭氧层或温室效应影响较大,使用对环境友好的制冷剂成为目前制冷行业发展的趋势。R290制冷剂作为天然工质应用在制冷系统中,具有更好的节能和环保效果,是替代R404A制冷剂在小型设备中应用的理想方案之一。在与R404A制冷系统的对比中,重点对制冷陈列柜中R290制冷系统的设计进行相关的分析和探讨。In the refrigeration system of commercial refrigeration display cabinet,Freon refrigerant is widely used.However,due to the impact of Freon refrigerant on the ozone layer or greenhouse effect,the use of environmentally friendly refrigerant is the development trend of the refrigeration industry.R290 refrigerant,as a natural working fluid,has better energy saving and environmental protection effect in refrigeration system.It is one of the ideal schemes to replace R404A refrigerant in small equipment.Compared with R404A refrigeration system,this paper analyzes and discusses the design of R290 refrigeration system in refrigeration display cabinet.
