Climate-friendly refrigeration in supermarkets
Systems with natural refrigerants have best climate balance - grants available for energy efficiency and use of natural refrigerants
Supermarket refrigeration systems that contain natural halogen-free refrigerants are the most climate-friendly of all technologies currently available for the purpose. These are the findings of Comparative assessment of the climate relevance of supermarket refrigeration systems and equipment research project, which was presented and discussed by over 50 experts at a conference held on 5 September 2008 at the Federal Environment Agency (UBA) in Dessau. At present, the costs for natural refrigerants are sometimes higher, but the costs for the systems will decrease considerably in the near future as mass production increases. Furthermore, conventional systems with synthetic HFCs as refrigerants must meet higher tightness standards in future, which will increase costs. ”Effective protection of the climate can only be achieved through large-scale use of natural refrigerants in supermarkets. Carbon dioxide as refrigerant can serve the purpose well since it is 3,300 times less damaging to the climate than the R 404A which is commonly used,” said Jutta Penning, Head of Division III at UBA. Many innovative und energy-efficient refrigeration systems using natural coolants are already available on the market.
