摘要
进行了 - 80°C的低温冷柜的设计计算 ,该低温冰柜采用自然复叠制冷循环 ,采用R2 2 /R1 4混合工质。文中涉及了蒸发器、冷凝器、冷凝蒸发器、中间换热器、毛细管和压缩机的设计计算。这种自然复叠式低温冷柜结构简单 ,在低温医学等方面有较好的应用。
This paper mainly deals with the design of a -80°C freezer,which performs Auto-cascade refrigeration principle and usee R22 and R14 as the zeotropic mixture refrigerant.The design calculations of evaporator,condenser,condensing-evaporator,medium heat transfer,capillary and compressor are described.This low-temperature freezer is characteristic for its compactness and it can be applied well in low temperature medicine and other regions.
