Sunbright Industrial Energy-Saving Air Conditioning Design Principle: The unit system combines evaporative cooling and vapor compression refrigeration technologies, achieving efficient heat exchange through a water circulation system, representing an innovative hybrid cooling solution. Its core advantage lies in utilizing wet curtain evaporative cooling as the primary cooling method, precooling the circulating water to near the ambient wet-bulb temperature, followed by secondary heat exchange through the indoor unit, significantly enhancing the system's overall coefficient of performance (COP). Specifically, when 30-35°C high-temperature circulating water flows through the wet curtain, water evaporation under the fan's action removes latent heat of vaporization, reducing the water temperature by 5-8°C. This cooled water then enters the condenser, rapidly cooling refrigerants such as R410A from high-temperature states, improving efficiency by 30-40% or more compared to traditional air-cooled condensers.

The system design particularly emphasizes graded energy utilization: after heat exchange, the warmed circulating water returns to the outdoor unit, where it is precooled by 3-5°C via air-cooled fins before evenly flowing through the honeycomb wet curtain via a water distribution system, forming a water film to increase the evaporation surface area. Test data show that under conditions of 35°C dry-bulb temperature and 50% relative humidity, the hybrid system's COP can reach 4.8-5.2, saving approximately 40% energy compared to traditional air conditioning systems.
