URDU.PK: History of A/C in Cars!!!

The modern type of air conditioning system had its predecessors. In the 1830s in Florida, a hospital employed a system that blew air over a bucket of ice to lend cooling to some of its patients. When President Garfield was on his deathbed, a similar device was used to keep his room cool. A device invented by Willis Carrier called an "Apparatus for Treating Air" was built in 1902 and was the closest direct ancestor of the air conditioner.

In the same year that Carrier's apparatus for treating air was created, Alfred Wolff designed an air conditioning system to cool the New York Stock Exchange. Wolff's system employed refrigeration equipment already in use, but the Armour Building in Kansas City, Missouri, became the first office building to install an air conditioning shortly afterward. Unlike Wolff's system, there were individual temperature controls for different parts of the building.

In 1904, many people got their first taste of air conditioning in the Missouri Building at the World's Fair in St. Louis. From there it was a gradual proliferation of air conditioning in office buildings, hospitals and other public places. In 1929, the first "room cooler," a small home air conditioning unit, was unveiled. It would be another 10 years before any type of air conditioning would be offered on a car.

The Packard automobile company debuted the first automobile air conditioning in 1939. It was rudimentary by modern standards. There was no control to adjust the temperature and the air was blown forward from the back of the car. Although this first attempt was awkward, by 1969 more than half the cars sold in the United States would have air conditioning.

According to a 2003 book by Susanna Robbins, at that time 98 to 99 percent of automobiles in the United States were equipped with air conditioning. It didn't just stop at cars, either. Trucks and even farm tractor cabs often have air conditioning built in. As a sign of the universal nature of car air conditioning, most vehicles are designed to be more aerodynamic with the windows up--with the most profound effect at higher speeds.
