doi:10.3969/j.issn.1008-0198.2026.04.005

Abstract

Abstract: The principles and advantages of direct, indirect and composite evaporative cooling systems are elaborated regarding their application in power plants. Combined with domestic and overseas engineering cases of power plants, the application of evaporative cooling technology in various scenarios is analyzed. Revit modeling and CFD numerical simulation are adopted for scheme optimization to compare the cooling performance of different ventilation systems during operation. Engineering practices demonstrate that evaporative cooling technology features low power consumption, water conservation, environmental friendliness and low cost. It can satisfy the ventilation and air conditioning demands of main power plant buildings, power distribution rooms and office buildings, as well as the cooling requirements of core equipment in thermal and hydropower plants. The technology delivers prominent benefits in arid and semi-arid regions, and can also be deployed in high-humidity areas after refined parameter adjustment. Its comprehensive benefits outperform those of some traditional cooling technologies.

Key words: evaporative cooling, refrigeration system, power plant, ventilation and air conditioning, energy conservation and emission reduction, digital design, renewable energy
