Résumé

This research delves into the intricate dynamics of the injection process within a visualization chamber designed to mimic a scroll compressor. Experimental investigations were conducted under diverse injection pressures, employing advanced image processing techniques to ensure a comprehensive analysis. The utilization of high-speed imaging allowed for the effective capture and visualization of the intricate details associated with the injection process. The application of the schlieren method played a pivotal role in accurately differentiating between R134a and CO2 based on variations in gas density. A meticulous methodology was employed to precisely track changes of the injection dynamics but also emphasized the considerable influence of both injection pressure and chamber pressure on the velocity of the injection tip. Furthermore, an examination of the cone angle under varying pressure conditions revealed notable observations. Specifically, as pressure differentials decreased, there was a discernible reduction in the injection stream. These findings contribute significantly to a deeper comprehension of vapor injection phenomena, providing valuable insights for the development of enhanced control and optimization strategies in refrigeration applications. The study paves the way for improved efficiency and performance in systems emulating scroll compressors.
