Résumé

This paper starts with an overview of refrigerant replacements during the last two decades and to the emphasis put on issues such as ozone depletion, global warming and energy efficiency. It presents estimated data on the demand of HCFCs and HFCs in developed and developing countries for 1995-2015. It also presents two scenarios, one a business as usual scenario and one for mitigating global warming emissions during the period up to 2030. A very important aspect to be taken into account is the growth in demand for new equipment that will occur in this timeframe, leading to a growth in climate-relevant emissions, even when emission rates for refrigeration and air conditioning (R/AC) equipment themselves can be kept low. Converting to low-GWP solutions, via both natural refrigerants and low-GWP fluorocarbons, may solve a large part of the growth in absolute climate terms. The current policy of the chemical industry is aiming at the availability of a sufficient number of low-GWP solutions, both as pure fluids and blends. The preference at the Multilateral Fund that supports developing countries in fulfilling their Montreal Protocol commitments is also focusing on the low GWP conversion away from HCFCs. Montreal Protocol Parties are asking for continuous updates on information in relation to the many issues involved in conversions or replacements. However, adequately addressing all the complexities involved in replacements will require a more holistic approach, which interlinks considerations on costs, energy efficiency, environmental aspects, engineering for different designs, design of refrigerant blends etc. This paper concludes with an analysis of these aspects and considers what may happen related to refrigerant options in the coming years.
