This work analyses different refrigeration architectures for commercial refrigeration providing
service to medium and low temperature simultaneously: HFC/R744 cascade, R744 transcritical booster,
R744 transcritical booster with parallel compression, R744 transcritical booster with gas ejectors,
R513A cascade/R744 subcritical booster, and R513A cascade/R744 subcritical booster with parallel
compression. The models were developed using compressor manufacturers’ data and real restrictions of
each system component.
Limitations and operating range of each component and architecture were
analysed for environment temperatures from 0 to 40
◦
C considering thermal loads and environment
temperature profiles for warm climates. For booster systems, cascade with subcritical booster with
parallel compression provide highest coefficient of performance (COP) for temperatures below 12
◦
C
and above 30
◦
C with COP increases compared basic booster up to 60.6%, whereas for transcritical
boosters, architecture with gas ejectors obtains the highest COP with COP increases compared
to the basic booster up to 29.5%. In annual energy terms, differences among improved booster
systems are below 8% in the locations analysed. In Total Equivalent Warming Impact (TEWI) terms,
booster architectures get the lowest values with small differences between improved boosters. [-]
