摘要
半导体制冷空气凝水是一种环保、洁净的取水方式。它利用帕尔贴效应,以电荷运输热量的方式,实现热电器件与空气的热量交换,从而达到空气凝水的目的。本研究探讨了使用热电制冷片对空气进行冷凝的效果。同时,用散热翅片作为空气制冷凝水的器材,测试了不同的散热翅片面积及涂覆憎水剂前后的产水量。结果表明,增加换热的面积和涂覆表面憎水剂,有利于提高取水量。
It is an environmentally-friendly and clean way of collecting water from air by using thermoelectric cooler. The heat exchange between the thermoelectric device and the air by the Peltier effect,lead to the direct water generation from air. This paper mainly studies the effect of thermoelectric cooling for air condensation. At the same time,the volume of water generation is measured when the heat dissipation fins worked as air condensate place to study the effect of the area of fins under the condition of with or without water repellent. The results show that increasing the heat transfer area and coating surface with water repellent is beneficial to increase the amount of water generation.
