Résumé

In its white paper, Danfoss presents its perspectives on the global trends within refrigerants in air conditioning and refrigeration. Danfoss stresses that there is no doubt that the environment will continue to play a very important role when defining the development and the usage of refrigerants. System manufacturers and users require long-term solutions that are environmentally benign, safe and affordable. Looking at the different alternatives, everything points to lower GWP solutions. Natural refrigerants are, by definition, low GWP solutions and they will become the preferred choice whenever possible. Safety will still be an important factor in regulating the usage of certain refrigerants. The trend clearly shows a growing acceptance of mildly flammable, A2L, refrigerants, especially now that they have been acknowledged by the new ISO standards. Also highly flammable, A3, refrigerants are increasingly used in smaller systems. Danfoss international group of experts made a projection on the refrigerant outlook within the main sectors and regions. CO2 is a widely used refrigerant in industrial refrigeration and commercial racks and Danfoss experts believe that this trend, which started in Europe, will extend to the rest of the world. Regarding the use of ammonia, they foresee that it will continue to be a very well accepted refrigerant particularly in industrial refrigeration, however, its toxicity means that safety measures will also have to be considered. It is very likely that in the future a solution using both CO2 and ammonia will be used. The outlook also acknowledges that hydrocarbons, which are very efficient refrigerants, will play an important role in low charge systems around the globe. Regarding the use of HFCs, they believe that they will not disappear, but those being used will have a much lower GWP. They project HFCs will begin moving towards more environmentally friendly, but mildly flammable, versions. When dealing with mildly flammable refrigerants safety has to be addressed as a key parameter.
