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。
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.
