The absorber is a crucial component in vapour absorption refrigeration systems due to lower heat and mass transfer coefficients during the absorption process. Among various absorber configurations aimed to improve the absorption process, bubble absorbers exhibit superior performance. The present study introduces a passive enhancement technique, employing a swirl generator to improve the bubble absorption process. The cavity-type swirl generator is placed in the refrigerant stream to impart swirl motion to the refrigerant bubbles. Experiments are conducted on a copper tubular bubble absorber within a vapour absorption system using R134a-DMF as a working fluid pair. Experimental investigations have been carried out by varying the operating parameters to evaluate the performance characteristics of the bubble absorber. The effect of the swirl generator is evaluated by comparing the solution heat transfer and volumetric mass transfer coefficients with the results in absence of the swirl generator. Results have shown that the swirl generator effectively enhances the bubble absorption process.
