Energy Class

Refrigerant refrigerant or refrigerant – is working substance, which has low temperature evaporation (ie boiling). Previously, all refrigerators with compression cooling in the role played refrigerant Freon-12 (R 12). This gas colorless and odorless. Gas that meets the requirement of a low boiling point, but There is one thing. Freon-12 contains chlorine. But chlorine is known to destroy the ozone layer of Earth's atmosphere, which protects all life on our planet from harmful cosmic radiation. So now its use in the production of refrigerators is prohibited.

To replace the freon came safe to the ozone layer refrigerants R134 and R600. 134th used in cost models, it is not so bad, but the 600th environmentally friendly, technologically, the use of CFC-600 shows a more modern implementation. Their composition does not include chlorine, so they do not deplete the ozone layer. Another striking feature of refrigerants is their fluidity. This index them higher than that of water, kerosene or even air. They are able to penetrate even through the pores of cast iron. But the motion of fluid in the pores of cast iron is an extremely complex process. Energy Class In total there are seven classes.

Each of them assigned to the Latin letter – from A to G. Accordingly, the best performance in energy efficiency of refrigerators, belonging to classes A, B and C. Superenergoekonomichnye refrigerators marked with A +. The letter D is assigned to an intermediate level of refrigerators. Well and, accordingly, those identified by letters E, F and G have high or very high level of energy consumption.
