A Brief History of Air Conditioning
Attempts to house roughly sort of artificial cooling during the summers of the American southeast began in the 1830s. These early efforts, however, yielded little in the way of pragmatical applications. Renewed efforts to develop a concrete vent conditioner gained some degree of urgency in 1881 following the shooting of president James Garfield. Garfield was shot in lateJuly, and over the come by 58 days before the President died temperatures hovered around 90 degrees and the humidity was uncomfortably high. The physicians attending Garfield persuaded government officials to call in naval engineers to solve the temperature and humidity problem in the President's sporting House bedroom.
The naval engineers were able to build a device, for inadequacy of a better word, that did provide some relief. The device consisted of a large cast iron box the size of a coffin (appropriate considering the venue) that "contained dozens of screens, each made of a clarified layer of terrycloth cotshort ton." A tank atop the box was kept filled with a halfton of shaved ice, salt, and water. As the ice melted, a briny glop formed and trickled down on the screens. A fan displace at one end of the box "sucked in argumentation from the outside, which was cooled as it passe

That both of these phenomena occurred in the region simultaneously, however, does not mean necessarily that change in either variable was the cause of the change in the separate variable.
The second development that enabled Willis Carrier to develop a realistic air conditioner was the demonst ration by Thomas Edison of a practical and efficient way to distribute electrical power. Edison's distribution carcass for the first time made it possible to provide an dirt cheap source of electrical energy to residential and commercial structures.

Air conditioners for the residential market continued to be trumpeted, however, through both advertising and promotional pieces in periodicals. Adverse articles around air conditioning, however, also appeared in the periodicals of the day. American City magazine ran an article contending that central air conditioning systems caused fires to spread at bottom a structure.
By the early1950s, the price of residential structures had change magnitude substantially, while the price of air conditioning systems for such structures had remained comparatively stable. The change in the structure/air conditioner price ratio exerted an almost magical effect on air conditioner gross sales which began to soar. One of the strongest and most effective marketing messages in air conditioning advertising and promotion in the early1950s was the ability of air conditioners to control the level of humidity within structures. Fortune magazine reported that the country was in the middle of an air conditioning boom in 1953. A ten-spot later, the marketing emphasis in residential air condit
