Pat Shingleton: "Carrier did it"
During our summer afternoon's the convective showers and thundershowers can drop the temperature from 92 degrees to 77 in 20 minutes. Air conditioning crews stay busy preparing and repairing the "A.C." units making sure they are "humming along." As mentioned in previous column, last Friday marked the 111th anniversary of the invention of modern air conditioning. In the 1900s, a Brooklyn printing plant was the first building in the world to be air conditioned by Dr. Willis Haviland Carrier. Older Baton Rouge homes utilized an attic fan to move air from room to room. Carrier's cooling plant divided air into two streams, one heated, another cooled. In each room, these two air streams are proportionately mixed to produce a desired temperature.
