The impact of using air and water cooling glass in the double slope solar still have been performed numerically and experimentally. The thermoelectric modules cold side cools a water flow which passes on the glass cover in the water-cooled solar still. On the other hand, the wind velocity was used to cooling the glass cover in the air-cooled solar still. The convection heat transfer coefficient is accounted as boundary conditions of the glass surface. Results show that the good agreement was obtained between numerical model and experimental data. The water productivity in water-cooled solar still was 81.1% more than an air-cooled solar still. Moreover, the effects of glass cover thickness, velocity and temperature of the water cooling glass on performance of a water-cooled solar still are performed. The output results, compared to water-cooled solar still, showed that this modification of water-cooled solar still increases the water productivity by 21.53%. Also, the cost analysis indicated that the cost of produced water for water-cooled and air-cooled solar still were about 0.243 $/L and 0.277 $/L, respectively. Based on the results, the CO₂ mitigation of air-cooled, water-cooled and modified water-cooled solar still were about 7.75, 13.09 and 16.27 tons, respectively. The enviroeconomic and exergoenviroeconomic parameters in the modified water-cooled solar still were improved by 24.3% and 632.1%, respectively, compared to the water-cooled ones.

在双斜率太阳能中使用空气和水冷却玻璃的影响仍然通过数值和实验得出。热电模块的冷侧冷却水流，该水流在水冷太阳能蒸馏器的玻璃盖上通过。另一方面，使用风速来冷却空气冷却的太阳能蒸馏器中的玻璃盖。对流传热系数被认为是玻璃表面的边界条件。结果表明，数值模型与实验数据吻合良好。水冷太阳能蒸馏器的水生产率比风冷太阳能蒸馏器高81.1％。此外，还进行了玻璃盖的厚度，水冷玻璃的速度和温度对水冷太阳能电池的性能的影响。输出结果，与水冷式太阳能蒸馏器相比，表明水冷式太阳能蒸馏器的这种改进仍将水生产率提高了21.53％。另外，成本分析表明，用于水冷式和风冷式太阳能的采出水成本仍然分别约为0.243美元/升和0.277美元/升。根据结果​​，CO₂空冷，水冷和改型水冷太阳能蒸馏器的缓解量分别约为7.75吨，13.09吨和16.27吨。与水冷太阳能电池相比，改进型水冷太阳能电池的环境经济参数和能效环境经济参数仍分别提高了24.3％和632.1％。
