Abstract: Refrigeration system design is one of the cores of refrigerators. Due to the different design concepts of various manufacturers, the current layout of refrigerator refrigeration system is more diverse. Based on the same conditions, four different layout schemes of refrigeration system are designed on the same box: back vertical, bottom, middle beam transverse, top, by means of theoretical calculation and flow field simulation, the comparison of ability and cost is to illustrate the advantages and disadvantages of each layout, and to provide some reference for future refrigerator design and refrigeration system layout.

Key words: Refrigerator, Refrigeration system, Refrigeration system layout, Flow field simulation
