Abstract

As the demand for cost-effective and sustainable air conditioning solutions grows, water based air-cooling systems present an energy-efficient and environmentally friendly alternative to commercial air conditioners. This paper introduces a passive cooling system using conical curved ducts and indirect evaporative cooling. Designed for the JNEC cafeteria, this system integrates wind catchers and a water-cooled conical duct mechanism to regulate room temperature effectively without refrigerants or compressors. Performance was analyzed using SolidWorks CFD simulation, validating temperature drop, air velocity, and duct efficiency. The results highlight a promising solution for large-scale, low-energy cooling in dry, hot climates
