| 为提升储存式冷热饮水机的冷水释放能力及降低能耗，本文提出了采用多层分水器替换单层分水器，延缓饮水机冷罐内常温水与冷水之间混合强度的实现思路。建立了多层分水器中结构参数与各层冷水温度、冷水量的数学关系，以及多层分水器结构参数的优化方法。给出了对于现有采用单层分水器储存式冷热饮水机，替换为多层分水器的优化设计实例；进行了样机的制作与性能测试。实验结果表明：在环境温度为32 ℃，冷水量释放能力相同的情况下，优化后的储存式冷热饮水机待机能耗可下降15%。 |

| Abstract: |
| This study proposes a novel method to improve the cold water supply capacity and reduce energy consumption using a multi-layer water separator to replace the single-layer water separator. This method can delay the mixing intensity between ambient temperature water and cold water and increase the average temperature under the standby state inside the cold tank. The relationship between the structural parameters of the multi-layer water separator, cold water temperature, and cold water volume in each layer is established, and an optimization method for the structural parameters is proposed. An optimized design example is given using a multi-level separator to replace the single-layer water separator in the storage hot and cold water dispenser, and an experiment is conducted. The experimental results prove that the standby energy consumption of the water dispenser fabricated using the newly proposed three-layer water separator is reduced by 15% with the same release capacity when compared with the baseline structure. |
