Aolan’s Indirect Evaporative Cooling Chilled Water Tower Selected for the Recommended Catalog of Energy-Saving and Carbon-Reducing Products for Refrigeration and Air Conditioning Applications

On October 29, the 2026 Technical Exchange Conference on Energy Conservation and Carbon Reduction in Refrigeration and Air Conditioning Applications was held in Chengdu. The conference was hosted by the China Refrigeration and Air Conditioning Industry Association and Hefei General Machinery & Electrical Products Inspection Institute Co., Ltd. It aimed to thoroughly implement the national decisions and arrangements on energy conservation, carbon reduction, and green development; accelerate the application of advanced energy-saving and carbon-reducing technologies and products for refrigeration and air conditioning; and promote high-quality, low-carbon, and standardized development of the refrigeration and air conditioning industry. During the conference, the Recommended Catalog of Energy-Saving and Carbon-Reducing Products for Refrigeration and Air Conditioning Applications (Third Batch) was issued, and Aolan’s independently developed indirect evaporative cooling chilled water tower was successfully selected.

Refrigeration and air conditioning systems are major energy consumers in industrial and commercial sectors, data centers, and other fields, and the energy efficiency of the cooling source system determines the overall energy consumption level. Aolan’s indirect evaporative cooling chilled water tower integrates indirect evaporative cooling and direct evaporative cooling technologies. With high-efficiency indirect evaporative cores and direct evaporative packing working together, it fully utilizes dry air energy to produce chilled water. Its outlet water temperature is 4–5°C lower than that of traditional open cooling towers, which can significantly extend the utilization duration of natural cooling sources, improve the overall efficiency of the cooling source system, and reduce data center PUE.

Based on these technical characteristics, the unit can achieve multi-mode intelligent operation throughout the year: in summer, when temperature and humidity are high, it operates as a cooling tower to provide low-temperature cooling water for mechanical refrigeration systems and improve chiller energy efficiency; in spring, autumn, and winter, it directly serves as a cooling source for terminal cooling, maximizing the “standby” time of mechanical refrigeration and significantly reducing overall system energy consumption.

In recent years, the product has been successfully applied in large newly built data centers in Shantou, Guangdong; Enshi, Xiaogan, Jingmen, and Shiyan, Hubei; Zhuzhou, Hunan; Chongqing; and other places across the country, helping data centers reduce PUE to below 1.3 and winning broad market recognition with stable and reliable performance.

Being selected for the recommended catalog is both recognition of Aolan’s technical strength by industry authorities and a heavy responsibility. In the future, Aolan will continue to deepen its work in evaporative cooling technology and, with more efficient and reliable products and solutions, help more industry users optimize their energy consumption structures and contribute to the green and low-carbon transformation of the refrigeration and air conditioning industry.
