Utilisation du GWP comme indicateur dans la sélection de frigorigènes.

The use of the GWP indicator in refrigerant selection.

Auteurs : KUIJPERS L.

Résumé

Today there is more interest than ever in the metrics of the GWP and climate indicators than ever. The EC F-gas Directive requiring suitable refrigerants for mobile air conditioning in Europe below a GWP 150 limit, the emphasis on the low GWP of natural refrigerants, the development of low-GWP unsaturated HFCs (also called “HFOs”) as alternatives for saturated HFCs, the explicit mentioning of climate friendly alternatives for HCFCs in the manufacturing conversion in developing countries, this all has caused that the metric GWP and the definition “low-GWP” and “high-GWP” have entered the discussion on refrigerant and equipment selection. If available and applicable, substitution of HCFCs in developing countries should preferably be to low-GWP alternatives and policy has directed substitution plans to be subject to environmental considerations including climate, with a possible financial “bonus”. This paper aims at the clarification of the GWP as an indicator via the radiative forcing parameter. It describes relevant Decisions of the Parties to the Montreal Protocol on climate relevance and on low-GWP technologies and refers to studies that have tried to define where the limit for “low-GWP” could be. It summarises the aspects of indicators used for equipment operation. It then summarises the climate impact of the 2007 decided HCFC phase-out and presents some concluding remarks on the use of “low-GWP” in relation to natural refrigerants and how equipment refrigerant choice optimisation could be done.
