| 具有冷冻冷藏双重功能的家用冰箱既能提高食品的储藏品质又能延长食品的储藏时间，在现代的家庭生活中发挥着重要作用，成为现代家庭必备的家用电器之一。冰箱冷冻冷藏室的布置方式对其室内温度场和流场的分布以及冰箱的能耗有较大的影响。通过对上冷藏室下冷冻室结构冰箱和上冷冻室下冷藏室结构冰箱室内温度场和流场的仿真发现：相对于上冷藏室下冷冻室冰箱而言，上冷冻室下冷藏室结构冰箱冷冻、冷藏室内温度分布均匀合理，既有利于食品的储存，又能降低冰箱的能耗。 |

| Abstract: |
| Household refrigerating appliances play an important role in our family life for their function of improving food storage-quality and prolonging food storage-time. Arrangement of the refrigerating chamber and the freezer greatly influences the temperature field and the flow field inside the refrigerator and energy cost of the refrigerator. Simulation of the temperature field and flow field inside the refrigerating chamber and the freezer in different arrangement indicates that household refrigerating appliances with the freezer on top, compared with the refrigerating chamber on top, have many advantages, such as rationality of temperature distribution, convenience of food-storage, and lower energy cost. |
