Results of the new study : ENERGY EFFICIENCY STATE OF THE ART OF AVAILABLE LOW-GWP REFRIGERANTS AND SYSTEMS

As an extension of the study published in 2014,  AFCE publishes here the final report of this independent study launched end of 2017 entitled energy efficiency of possible alternatives . The study has been carried out by experts from EREIE – CEMAFROID and CITEPA.

This study considers only pure refrigerants or mixtures with a standardized number according to the latest update of ASHRAE 34. The comparison of the proposed options is based on the feedback of the owners and operators referred to facilities using these alternatives, on guarantees from equipment manufacturers or on publications (journals, conference papers) submitted to a steering committee. The many sectorial  summary sheets published alongside the report allow end-users or installers to find out quickly, on a single sheet, solutions for each application domains and to make a choice thanks to a multicriteria indicator that graphically represents the 6 technical and economical parameters in order to highlight the advantages and disadvantages of each option.

This study, funded by AFCE and a few of its members,  is freely available on AFCE website, demonstrating our willingness to help the refrigeration & air conditioning industry stakeholders.
