Conversion of a Direct to an Indirect Refrigeration System at Medium Temperature Using R-134a and R-507A: An Energy Impact Analysis
MDPI (2018-02-06)This work presents the experimental evaluation of energy consumption and refrigerant charge reduction when a commercial direct expansion refrigeration system is converted into an indirect system. The evaluation (with R-134a ... -
Energy assessment of an R134a refrigeration plant upgraded to an indirect system using R152a and R1234ze(E) as refrigerants
Elsevier (2018-07-05)In this work the experimental results obtained from a direct expansion refrigerating plant converted into an indirect plant, are presented and discussed in terms of energy consumption for a commercial refrigerating unit ... -
Energy evaluation of a Low Temperature commercial refrigeration plant working with the new low-GWP blend R468A as drop-in of R404A
Elsevier (2021-01-20)This work analyses experimentally the energy behaviour of a centralized commercial refrigeration plant designed to be used with R404A (GWP100=3,943) at low temperatures, when it is replaced with the new low-GWP refrigerant ... -
Experimental analysis of R-450A and R-513A as replacements of R-134a and R-507A in a medium temperature commercial refrigeration system
Elsevier (2017-09)This work presents the experimental evaluation of R-513A (GWP = 573) and R-450A (GWP = 547) as R-134a (GWP = 1301) drop-in replacements and as R-507A (GWP = 3987) retrofits in a commercial direct expansion refrigeration ... -
Experimental evaluation of the desuperheater influence in a CO2 booster refrigeration facility
Elsevier (2020-03-05)Commercial refrigeration has undergone significant changes in recent years. In the European market, this is mainly due to the F-Gas Regulation (EU 517/2014). F-Gas affects in great measure to commercial centralized ... -
Influence of subcooling in R-449A supermarket refrigeration system and screening of refrigerant mixtures for its energetic and environmental improvement
Elsevier (2024-01-10)Current demands of the cooling sector are focused on using refrigerants with a low Global Warming Potential (GWP) and increasing energy efficiency in vapour compression installations. The main objectives of this paperwork ... -
Influence of subcooling in R449A supermarket low-temperature refrigeration circuit using medium temperature cooling load
Institut International du Froid (2023-04-05)This work studies the impact of subcooling in supermarket refrigeration systems with medium and low-temperature requierementsbased on a vapor compression single-stage with a subcooler.
