| 中文摘要: |
| 为了有效解决散装食用油在储藏过程中高温季降温速率缓慢、降温成本高的问题，提出了一种内置冷媒管的降温方法，并基于该方法搭建了油罐控温实验台。在实验过程中通过调整冷媒流动方式、冷媒温度和流量，进行了20组对比实验，对不同工况下的降温效果进行分析。结果表明：在上供式高流量下，冷媒温度8 ℃与冷媒温度16 ℃时相比，储油均温与冷媒温差相差3.2 ℃；在冷媒温度为12 ℃时，增加流量对降温效果的影响最为显著。与冷媒下供式降温相比，采用冷媒上供式可降低储油上下层的温差，并可更有效地阻隔外界热量向罐内传递。 |

| In order to increase cooling rate and cut down the cooling cost of storage for edible oil in hot season, a cooling method with inner refrigerant tube was proposed. Base on this method, a temperature control experiment system was set up. In the process of the experiment, 20 groups of experiments were carried out by adjusting the flow mode (top-bottom and bottom-top), flow temperature and flow rate of the refrigerant to analyze the cooling effect under different working condition. The results showed that under the working condition of a top-bottom flowing and high flow rate, the difference between the average oil temperature and the temperature of the refrigerant decreased by 3.2 ℃ at 8 ℃ inlet temperature compared with that of the 16 ℃. When the refrigerant temperature was 12 ℃, increasing the flow rate had the most significant effect on the cooling effect. Compared with the refrigerant flow of bottom-top, the refrigerant flow of top-bottom could cut down the temperature difference between upper and lower layers of the oil storage and effectively block the transfer of external heat to the tank. |
