    i dont mind the monochrome tanks, is it that hard to read the rating plate

    oh wait....sometimes that near impossible! gotta love the mfg'rs that use non UV ink and or hide the damn label where its impossible to see unless you uninstall the unit.
    my boss thinks its possible to repeal the laws of physics

    I hear r290 is a very efficient refrigerant. I should look it up compared to 22 and 410.

    If it is efficient I wouldn’t care to go the that. Should really thwart off some of the diy and low ballers as well. If not, we’ll I guess they call that Darwinism.

    Very likely. I believe some European manufacturers like Mercedes already have vehicles with CO2. We will probably see the use of CO2 spread. And after that I guess there will be a hunt for refrigerants that have a GWP < 1. R-1234yf supposedly has a GWP < 1 but former studies show it to be around 4 so I believe there is some debate about that.

    I went through a presentation on future refrigerants by a guy from another major brand. He said when the next refrigerant changes happen in the 2020s, it could be that each pick their own desired gas though like us, he hoped everyone would standardize on 1. Carrier & Daikin likely have the most influence on that choices so be interesting to see what Daikin announces, if anytime soon.

    1234yf is being used in cars but didn't hear of planned usage in stationary.

    I think R1234yf is going to be way too expensive for larger systems....it's a replacement for R134a, not R410A. When looking at R134a alternatives, it seems R1234ze is growing in popularity as is R513A. Coming back to R410A alternatives, R454B was developed to be a drop in for R410A so it's a nice short term solution. R32 is higher pressure but also gives you more capacity. R452B is a nice intermediate. At the end of the day, I think (worry) we're going to end with with an alphabet soup of refrigerants out there. Different for RTU vs chiller vs resi.

    R454B was specifically developed to be a drop in for R410A. Pressures, temperatures, capacity, etc all nearly identical (+/- a few %)

    And it's only mildly flammable.
