    117 years of the air conditioner


    A bit too big for your apartment window.
    There are some drawback to it beside living in ultra-dry air. No more large, shady patios or sitting in the window to talk with neighbors. No more spacious front porches to catch the evening air and socialize with others.
    Iím sitting at my computer right now wearing a long-sleeve shirt to fend off the cold air from our a/c.
    In July of 1902, an engineer named Willis Carrier designed the world's first modern air conditioning system. The design was to cut the humidity level at the Sackett & Wilhelms printing plant in Brooklyn, New York.
    "It was so hot that summer that the ink would not stick to the paper. It was too humid," said Rackley. "So he developed a device that would pass air over coils that were cooled by a refrigerant, I guess it was called water then, that pulled the moisture out of the air and they were able to print."
    There was a happy side effect from that design. The temperature inside the factory became more pleasant and pretty soon, they were installed at other factories and businesses.
    "When it first came out, movie theaters are where folks would show up," said Rackley. "You would go to the movies not only to watch a movie but to stay cool. It was dark and cold. You could sit comfortably and get out of the heat."

    Willis Carrier wasn't a WOC or LBGQWERTY!

    The first refrigerant was indeed water, but water won't give you particularly cold supply air. Carrier moved on to ammonia which will give you Arctic-cold supply air. It is still used for industrial cooling where really cold temps are required.

    Yet even with the existence of air conditioning the tradition of escaping the heat in Washington, D.C. by taking August off is still embraced by politicians.

    I am not saying politicians are lazy just because they take the month of August off and at least a week off for every Federal holiday. Well actually I am.

    I used to walk 2 miles a day when it was hot. Heck I once got home & found out that it was 105 degrees. Not any more. Today it was 103 & I LOVE my AC unit.

    How many recall the term "Ice Box?"

    In the old days refrigeration was industrial size. So they had a man who delivered a block of ice for the top of your home unit.
    "Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free."

    - Ronald Reagan

    I think there's still a place here in Vegas that sells ice by the block.

    Back in my working days at Tropicana, we were always taking ammonia safety classes. Ammonia is awesome as industrial cooling. But it will kill ya in a heartbeat.
