Vergleichende Bewertung der Klimarelevanz von Kälteanlagen und -geräten für den Supermarkt.

After the entering into force of EU regulation (EC) No. 842/2006 and the EU directive 2006/40/EC, refrigeration systems in supermarkets remain the last big subsector and the strongest emission source of fluorinated hydrocarbons (HFC) in Germany. The first part of the survey, published in the magazine Climate Change, offers a comprehensive overview of HFC free refrigeration systems for supermarkets offered and applied in Europe. It contains a market survey of supermarket refrigeration systems that are completely or partially operated with HFC free refrigerants, including information on their actual market penetration in the EU. Beside the respective relevance of the technology in the market, it is also displayed to what extent appropriate operational experiences exist. The second part offers information about the energy efficiency and economics of the HFC free systems in comparison to conventional systems on the basis of the total equivalent warming impact (TEWI). In the third part, technical, economic and structural barriers for the expansion of the future insertion of natural refrigerants are identified. Furthermore, steps are described for short- and mid-term options for overcoming market launch barriers. Additionally recommendations for potential subsidies for the promotion of HFC free refrigeration systems are developed.
