    "New" R507/R404 replacement



    Has anyone heard of a "new" R507/R404 replacement? I have heard the blend will be changed to replace the R134a in the blend with I believe it is R123 and therefore lowering the GWP to less than the R407 gases but keeping the same properties. Anyone heard anything about this?

    Thanks

    Re: "New" R507/R404 replacement

    Greetings Coorsman, Something doesn't sound right here. R-123 is a chlorine containing HCFC and is scheduled for phase out for ozone depleting reasons, so I doubt it is being used in replacement blends. There is a relatively new refrigerant, R-1234yf which might be what you heard about. It is a very low GWP gas with properties similar to R-134a and is being adopted by the automotive industry to replace R-134a in mobile AC applications. 1234yf is also starting to be looked at as a blend component for stationary applications but these are still a way off in the future but with ever increasing regulatory pressure to lower GWP products it is the direction the industry is headed. I hope this helps. Cheers
