设计并建造了一种用于生产饮用水的高效热电蒸馏系统。该系统的独特设计是利用热电模块热侧的热量同时进行水蒸发和冷侧的蒸汽冷凝。这种新颖的设计大大降低了能耗，提高了系统性能。实验结果表明，在充满10 × 10 × 30 mm（3）水的蒸发室中，平均产水量为28.5 mL/h，比能耗为0.00114 kW h/mL。这明显低于其他现有热电蒸馏系统所需的能耗。结果还表明，热电模块的热侧和冷侧之间的最大温差为42.3摄氏度，这导致水和蒸汽的温度分别升高26.4摄氏度和8.4摄氏度。(C)2016爱思唯尔有限公司版权所有。
An efficient thermoelectric distillation system has been designed and constructed for production of drinkable water. The unique design of this system is to use the heat from hot side of the thermoelectric module for water evaporation and the cold side for vapour condensation simultaneously. This novel design significantly reduces energy consumption and improves the system performance. The results of experiments show that the average water production is 28.5 mL/h with a specific energy consumption of 0.00114 kW h/mL in an evaporation chamber filled with 10 x 10 x 30 mm(3) of water. This is significantly lower than the energy consumption required by other existing thermoelectric distillation systems. The results also show that a maximum temperature difference between the hot and cold side of the thermoelectric module is 42.3 degrees C, which led to temperature increases of 26.4 degrees C and 8.4 degrees C in water and vapour, respectively.
