This thesis illustrates in detail how to design a 550Lbetween any case steps and related calculation method. Such as the thickness of the insulation blanket, outer wall of the fridge dew checking, thermodynamic calculation of the cooling system, the choice of the compressor, evaporator and condenser thermodynamic calculation and the calculation of the capillary length. In addition this article also refrigerators for the future development trends, skills, technology is also introduced some, points out that the household refrigerator should be towards energy saving, environmental protection, intelligent and multi-functional direction development. 8 Key Words：Indirect cooling；Household refrigerators ；energy conservation and environment protection 9 前 言 世界上首台家用的制冷设备在1910年左
