Simplified ejector-supported R744 booster system.
Number: 0696
Author(s) : ROOS F., HAFNER A., DAVID L., BANASIAK K.
Summary
Transcritical R744 booster systems are the preferred solution in commercial refrigeration. Technologies such as parallel compression and expansion work recovery are established to improve them. Previously, when installing energy efficient R744 refrigeration systems in warmer climate regions, it demanded a higher level of complexity and investment costs to further improve these units.
This work presents the first measured field data of the Simplified Ejector-Supported Booster (SEB) system, benchmarked against a parallel compression system. The field data are gathered from two food retail stores in Portugal over a seven-month period. The results demonstrate that the SEB configuration outperforms the parallel compression (PC) system in terms of specific energy consumption under all ambient conditions.
