A Design Study on the Use of the Archimedes Windmill for Energy Recovery in Cooling Systems

Abstract

A complete study on the design and performance assessment of Archimedes Windmills as integrated components for HVAC cooling systems in energy recovery applications appears in this paper. Performance analysis of three blade configurations using computational fluid dynamics simulations demonstrated the best aerodynamic results when operating at rotor speeds between 60–180 RPM with 3 blades. The 3-blade setup at 120 RPM reached top performance standards with 1.82 Nm torque generation and 35.2 W power delivery. The tested design reached a power coefficient (Cp) level of 0.42 surpassing standard Savoniustype turbines by approximately 28 to 40 percent under identical circumstances. Exams showed that turbine blades boosted torque performance while generating more drag that decreased efficiency when speeds rose. The output power became unstable when the turbine operated with fewer blades but achieved higher rotational speeds. A proper design will combine blade configurations to achieve top efficiency while maintaining stable power outputs. Steel firm evidence shows that the Archimedes Windmill provides efficient and space-saving energy retrieval capabilities for HVAC systems. The research data will function as valuable reference information when designing sustainable building infrastructure for future implementation. Additional study is needed to develop the operational stability of the system while conducting experiments and evaluating cost efficiency for large-scale commercial adoption.
