    Because it comes in a green bottle.

    I got a pretty good laugh from that.

    It's so funny, yet so true.

    That was funny as hell, but the other side of me with common sense wants to cry.

    You gotta really love the part where they say they don't even use re-captured CO2. They actually CREATE MORE CO2, then it takes even more energy to operate [creating even more CO2]. Freakin' whacko's.

    That is awesome, leave it to the cartoons to make sense.
    There are two ways to do things, Right and Again.

    Too bad it's half bull****. Stores with CO2 systems save a heck of a lot on their energy bills because it is actually more efficient. The exception is if you try to use a transcritical system in the south, which doesn't work out as well as in the north.

    I don't know anything about using CO2 as a refrigerant. So which is it? Is it more efficient, or is it less efficient than other more conventional refrigerants? Speaking strictly of electricity used to provide a certain amount of cooling. Not the extra installation cost.

    In terms of absolute energy consumption, it is more efficient.

    It costs a lot more because it runs at 2000 PSI on the high side (for a transcritical system) and efficiency drops like a rock if the condenser ambient is above 87 degrees F, but subcritical systems that work in a cascade with an ammonia system are still more efficient than F-gasses and can be used year round in any climate.

    Interesting. Now the entirety of my CO2 knowledge is comprised from the two training videos on this thread.
