Stronghold for 1234yf is crumbling - part II. By R744.com team , May 07, 2010, 13:51. High refrigerant costs, the need for new plants and pending patent issues put the use of HFC-1234yf more and more into doubt. Several publications have been made available as part of the ‘Improving Cold Storage Equipment in Europe’ (ICE-E) project deliverables. Included in an information pack is a document that analyses the main advantages and disadvantages of the most widely used refrigerants in cold stores and food processing, namely R404A and R717 (NH3, ammonia), when employed in mechanical compression The environment-friendly A/C system by Behr being introduced in 2003 is more powerful than a conventional system. However, the requirements have changed: Instead of a higher cooling performance, the same performance of a R744 system is expected in comparison to a state-of-the-art system with R134a, with minimal additional costs. The second generation R744 system fulfils these requirements. CO2/r744 is a Global Warming Potential of just 1.
