Cooling towers are extensively utilized in diverse industries for efficient heat dissipation. Fill media are a critical component, facilitating heat and mass exchange between water and air, impacting overall cooling tower efficiency. Given its vital importance, this study comprehensively reviews recent advancements in fill media technology, illuminating cooling tower technology progress and exploring the effects of different fill media configurations and materials on cooling tower performance. It should be noted that the majority of research is focused on the Range of 2.5 °C to 25 °C and Approach of 1 °C to 9 °C. Through comprehensive analysis and evaluation, the effects of various fill media on heat transfer efficiency, water cooling capacity, and energy consumption are intensively summarized. By understanding these effects, engineers and designers can make rational decisions to optimize cooling tower performance and ensure efficient heat dissipation. Notably, in some reported cases, new fill media enhanced cooling range, effectiveness, and the Merkel number by 28%, 85%, and 131%, respectively. Ultimately, this paper serves as a valuable resource for academics, researchers, and professionals in the field of cooling tower design and thermal management. The insights provided in this study can help industries achieve greater energy efficiency, sustainability, and overall operational excellence.

The performance of the cooling tower is profoundly influenced by the climatic conditions. This study examines cooling tower performance in 42 diverse Saudi Arabian cities, addressing gaps in existing literature considering the performance parameters of temperature range, and cooling capacity. To assess the performance of the cooling tower, a mathematical model is developed and solved using the Engineering Equation Solver (EES). The assessment of the cooling tower's performance is conducted with a focus on yearly and monthly average dry-bulb temperatures as well as relative humidity. Based on the yearly average weather data, the cooling tower in Jazan exhibits the lowest performance with a temperature range of 4°C and a 50-kW cooling capacity. In Abha, the cooling tower demonstrates the best performance despite different weather conditions with almost a 7.61°C range and 95.4-kW cooling capacity. Evaluating the monthly average weather data, the cooling tower in Abha excels compared to the cooling tower in the other cities, achieving a cooling capacity of 86.1-kW in August outperforming its counterpart in Jazan by 53.5%. The summer weather conditions in Abha have led to a slight reduction in the cooling capacity of only 16.3% in comparison to the cooling capacity in winter (January).

“…Improvement of evaporation can reduce the wet ball by 85-95%, while the filler surface affects the decrease in the ratio of water mass flux to air [4,5]. Interesting results have been obtained using a fill made alternative material such as pebbles, PET strip, and coconut husk and energy loses also reduced using alternative fill [6,7]. Gao et al, [8] demonstrated that wind speed affects efficiency and temperature decrease.…”

Cooling systems using colling towers are often an important element in a production process and always involve water or energy consumption. Therefore, increasing the efficiency of the colling tower will reduce water and / or energy consumption. In order to increase the efficiency of colling tower energy consumption, the most studied part is the fills, where heat transfer occurs. However, there are no studies on the use of vortex generators in colling tower fills. Hence the aim of this study was to evaluate the performance improvement in a forced draught cooling tower using a vortex generator. It was conducted on a laboratory scale using single fill as a trial medium. The fill was made of 3-mm acrylic with dimensions of 30 × 30 × 1950 mm. A three-unit vortex generator was placed inside the fill. The rectangular vortex generator was made of 0.5-mm thick aluminium and had a size of 50 × 10 mm. Data were retrieved for the fills with and without a vortex generator. Water and air discharge of 1 L/minute and an inlet water temperature of 60°C were maintained. The results indicated that the effectiveness of the fill with a vortex generator was increased by 90.72% compared to the fill without a vortex generator.
