Résumé

This paper reports experimental investigations on a retrofitted commercial booster rack with scroll compressors featuring dynamic vapour injection (DVI). First presenting the initial CO2 rack and exemplary results of a state-of-the art booster system, the paper then focuses deeper onto the retrofitted unit. Experimental measurements with two system architectures are presented, namely with flash tank DVI and economizer DVI configurations. For both layouts, mechanisms leading to performance improvements are described, so as the main parameters driving the rack operational behaviour. Finally, a performance comparison is done between the various architectures tested with the booster rack, including flash gas by-pass, parallel compression, gas ejector and dynamic vapour injection.
