Summary

F-Gas regulation imposes a gradual reduction of greenhouse gases emissions, among which fluorinated refrigerants with high global warming potential (GWP).The most used refrigerant in commercial refrigeration, the R-404A, will be banned from 2021. Users shall consider the replacement of this refrigerant. This paper presents a study for the replacement of R-404A by R-442A in a supermarket low temperature refrigeration unit. A two weeks registration campaign was conducted. One week before replacement (R-404A utilization) and one week after (R-442A utilization). The instrumentation of the refrigerated display cabinets and the refrigeration units by temperature sensors and electric analyser allows measuring the refrigeration consumption in the supermarket. Consumptions obtained using the R-404A are compared to the ones obtained using the R-442A.Results show a good conservation of the performance of the installation and a decrease in operating time and power consumption of around 5% with the R-442A.
