Screw compressors are vital in industrial and commercial applications because to their efficiency, reliability, and longevity. Nonetheless, obstacles persist in improving their energy efficiency and performance, particularly under fluctuating operational requirements. This study examines the influence of critical parameters—specifically, profile clearances, geometric design, and fluid injection strategies—on compressor efficiency and durability. This research presents a thorough investigation of the interdependencies among these parameters, emphasizing the enhancement of compressor performance, in contrast to prior studies. This work is innovative because of its twin approach: first, it experimentally validates the impact of oil and water injection on compressor performance, and second, it utilizes a chamber-based model to analyze the implications of various parameters in greater detail. The experimental results demonstrate that water injection reduces specific power consumption by 4.59% compared to conventional oil injection, highlighting its potential for enhancing energy efficiency. This study offers significant insights into compressor design and operation, identifying optimal designs for diverse applications and pressure ratios. The findings enhance the comprehension of parameter interactions and fluid injection impacts, aiding in the advancement of more sustainable, high-performance screw compressors.
