Numerous studies have been conducted over the past decades to improve the performance of energy systems using nanofluids. This research seeks to evaluate the effect of the simultaneous use of thermoelectric cooling and heating application with various nanofluids on the performance of solar still. The nanofluid temperature decreases with thermoelectric cold side in the cooling tank and flows on the glass by the pump, resulting in reducing the temperature of the glass. Simultaneously, the thermoelectric hot side increases the nanofluid temperature in the heating tank and flows into a helically coiled heat exchanger inside the solar still. The base fluid in cooling and heating tank was replaced by Al₂O₃, TiO₂, CuO and MWCNT nanofluids at concentrations of 0.1, 0.3, 0.5, 0.7, and 0.9%, and their effect on the temperature difference between saline water and glass were examined. The results showed that water productivity of solar still with the thermoelectric cooling and heating and Al₂O₃, TiO₂, CuO and MWCNT nanofluids at a concentration of 0.9% were improved by 11.57, 7.16, 6.32, and 4.66%, respectively, compared to solar still without nanofluid. Also, the results showed that the water productivity, thermal efficiency, and ${\text{CO}}_2$ mitigation of solar still improved with increasing the concentration of the nanoparticles in the base fluid. The presented thermoelectric solar still provided a low cost per liter (CPL) by 0.098 $/L/m².

在过去的几十年里，已经进行了大量的研究来改善使用纳米流体的能源系统的性能。本研究旨在评估同时使用热电冷却和加热应用与各种纳米流体对太阳能蒸馏器性能的影响。纳米流体温度随着冷却槽中的热电冷侧而降低，并通过泵在玻璃上流动，从而降低玻璃的温度。同时，热电热侧提高加热罐中的纳米流体温度并流入太阳能蒸馏器内的螺旋盘管换热器。冷热罐基液更换为Al ₂ O ₃、TiO _{2 。}检查了浓度为 0.1、0.3、0.5、0.7 和 0.9% 的 CuO 和 MWCNT 纳米流体，以及它们对盐水和玻璃之间温差的影响。结果表明，热电制冷和加热的太阳能蒸馏器和浓度为0.9%的Al ₂ O ₃、TiO ₂、CuO和MWCNT纳米流体的产水率分别提高了11.57、7.16、6.32和4.66%。太阳能仍然没有纳米流体。此外，结果表明，水生产率、热效率和${\text{二氧化碳}}_2$随着基液中纳米颗粒浓度的增加，太阳能的缓解仍然得到改善。所展示的热电太阳能仍然提供了 0.098 美元/L/m ²的低每升成本 (CPL) 。
