The evaporation phenomenon is used as a passive cooling approach to absorb the sensible heat and convert it into the latent heat. The usage of evaporative cooling systems has boomed, recently, because of its low operational cost. The Direct Evaporative Cooling (DEC) systems can be used widely in warm dry environmental conditions, such as Middle East countries. Several factors can affect the DEC system such as water temperature, evaporative cooling pad thickness, air velocity, and solar radiation flux. In this study, the performance and water consumption of evaporative-based cooler manufactured by RFX Polycarbonate-Structured Sheet (PSS) are compared with the metal-casing one. The impacts of tilting the roof of the cooler and attaching a glass wool-aluminum foil on the cooler are evaluated. The assessments show about 20.6% reduction in the usage of water for the case of RFX Polycarbonate-Casing cooler compared to the metallic material. Results also revealed that tilting the roof saves 29% water compared with the metal-casing cooler while changing the inclined roof to the glass wool-aluminum foil radiation shield further saves the water by about 25%. The performance of the RFX-PSS cooler is enhanced by about 4.7% as compared to the metal-casing cooler. The improvement of 8.1% occurs by tilting the roof in RFX Polycarbonate-Casing cooler in comparison with the metallic DEC system and attaching the isolation foil of glass wool-aluminum instead of the inclined roof increases the saturation efficiency by 7%.

蒸发现象被用作被动冷却方法，以吸收显热并将其转化为潜热。由于其较低的运行成本，蒸发冷却系统的使用近来已蓬勃发展。直接蒸发冷却（DEC）系统可广泛用于温暖干燥的环境条件下，例如中东国家。几个因素会影响DEC系统，例如水温，蒸发式冷却垫厚度，空气速度和太阳辐射通量。在这项研究中，将RFX聚碳酸酯结构板（PSS）制造的蒸发式冷却器的性能和耗水量与金属壳体进行了比较。评估了倾斜冷却器顶部并将玻璃棉铝箔附着在冷却器上的影响。评估显示约20。与金属材料相比，RFX聚碳酸酯套管冷却器的用水量减少了6％。结果还显示，与金属外壳冷却器相比，倾斜屋顶可节省29％的水，而将倾斜屋顶更改为玻璃棉-铝箔辐射防护屏则可进一步节省水约25％。与金属外壳冷却器相比，RFX-PSS冷却器的性能提高了约4.7％。与金属DEC系统相比，通过将RFX聚碳酸酯套管冷却器中的屋顶倾斜，并附上玻璃棉-铝隔离箔而不是倾斜的屋顶，可以将饱和效率提高7％，从而提高了8.1％。结果还显示，与金属外壳冷却器相比，倾斜屋顶可节省29％的水，而将倾斜屋顶更改为玻璃棉-铝箔辐射防护屏则可进一步节省水约25％。与金属外壳冷却器相比，RFX-PSS冷却器的性能提高了约4.7％。与金属DEC系统相比，通过将RFX聚碳酸酯套管冷却器中的屋顶倾斜，并附上玻璃棉-铝隔离箔而不是倾斜的屋顶，可以将饱和效率提高7％，从而提高了8.1％。结果还显示，与金属外壳冷却器相比，倾斜屋顶可节省29％的水，而将倾斜屋顶更改为玻璃棉-铝箔辐射防护屏则可进一步节省水约25％。与金属外壳冷却器相比，RFX-PSS冷却器的性能提高了约4.7％。与金属DEC系统相比，通过将RFX聚碳酸酯套管冷却器中的屋顶倾斜，并附上玻璃棉-铝隔离箔而不是倾斜的屋顶，可以将饱和效率提高7％，从而提高了8.1％。
