1、论文-一关于复叠式制冷关于复叠式制冷摘要复程式制冷广泛应用于工业产品的热处理过程和金属的冷处理，广泛应用于军工、航空、航天、化工、页药、机械制造等行业。原因就是它有如下几方而的优势：复叠式制冷采用环保制冷剂，符合国际环保要求：性价比高，价格仅为进口同类产品的1/3〜1/2；操作简单，采用智能变频PID控制及多点无接触测温系统；主要元器件全部采用国际知名品牌，完全可替代进口同类产甜；复程式制冷系列自动复輕循坏制冷机结构紧凑，可靠性高，操作简便，在能源、军工、空间、生物、医疗和生命科学等高科技领域内有着广泛的应用。国内外学者纷纷対自动复叠制冷技术展开了新的研究。忖前，自动复叠制

2、冷循环呈现出新的发展特点，对其研究主要集中在两个方而：一方面是对原有的制冷循环流程的改进，包括采用新型换热器和高效气液分离器；另一方而则是采用新型的制冷工质，包括二元工质和多元工质，以满足环保和制取低温的要求。木文就复證式制冷的原理在与双级制冷的对比Z下做出阐释，希冀能更进一步对复叠制冷的理解。关键词双级制冷复叠式制冷AbstractCascadetyperefrigerationwidelyusedinindustrialproductsofheattreatmentprocessandmetalcoldtreatment,versatileapplications,av
