| 摘 要： | 为控制冰温库融霜时的温度波动,提出采用附加冷却器制冷来抵消融霜剩余热负荷的新方法。实验结果表明,在文中的实验条件下,附加冷却器不制冷时,融霜时的库温回升在4.3℃以上;附加冷却器制冷时,融霜时的库温波动在0.5℃以内,能够满足冰温库的技术要求。另外,有附加冷却器制冷的融霜时间有所增加。

| Abstract: | In order to limit the temperature fluctuation,a new method of countervailing the surplus defrost load by using additional-cooler was proposed in this article.The experimental data were analyzed for given experimental conditions.The results show that without additional-cooler the temperature of cold storage goes up again over 4.3℃ during defrosting.With the additional-cooler,the temperature fluctuation of defrosting can be limited below 0.5℃,which meets a criterion of ice-temperature storage.Otherwise,with the additional-cooler,the time of defrosting prolonged. |
