Retrofit of refrigeration installations with low GWP refrigerants

Technological developments in the refrigerant industry based on the limitations imposed by REGULATION (EU) 2024/573 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 7 February 2024 on fluorinated greenhouse gases, amending Directive (EU) 2019/1937 and repealing Regulation (EU) No. 517/2014 have aligned with this regulation and, together with refrigeration equipment manufacturers, have begun to introduce refrigerants with a GWP (Global Warming Potential) of less than 150 units into the European market. This paper presents a method for the modernization of small and medium-sized commercial refrigeration installations using refrigerants such as R448A or R449A, as well as the technical implications that must be taken into account in the modernization process.
