| 库中增加蓄冷系统可以起到稳定库内温度、延长保鲜时间的效果，与峰谷电价结合，还可以实现良好的经?济性。利用保温箱模拟冷库，在保温箱安放相变蓄冷板，板内充注水作为蓄冷液，所用蓄冷液体积与保温箱的容积比为1:30。通过测试分析蓄冷保温箱内的保温效果、空间温度分布及传热温差，验证了内部采用蓄冷板系统的冷库，在电价高峰期的8小时之内，温度波动小于0.6℃，库内各点最大温差为1.1℃，能够达到货物保存的要求及节能的效果，为冰蓄冷技术在冷库系统中的应用奠定理论和实验基础。 |

| Abstract: |
| Phase change storage(PCS) system added into the cold storage can stabilize the temperature of the cold storage, extend the preservation time, and achieve a good economical efficiency combined with the peak-valley price. Storage boards were installed as a test system in an incubator, which are filled with water, and the volume ratio between the PCM and the incubator is 1:30. By analyzing the insulation effect, the temperature distribution and the temperature difference between the PCM and air, the experimental data showed that the cold storage with phase change storage system had a temperature fluctuation of 0.6℃ and the maximum temperature difference is 1.1℃, so it can satisfy food fresh-keeping demands and achieve good economical efficiency. This result is important for the phase change storage system to be used in the cold storage. |
