HOME Air-conditioner

                                    In the summer of 1902, a printer in Brooklyn New York, was having trouble with colour  printing because the hot, humid weather was causing the paper on the presses to change size enough to cause distortions of printing. Willis Haviland Carrier, a young engineer trying to solve the problem, found that air retained less moisture at lower temperatures. He designed a machine that flew air over chilled pipes and stabilized the Carrier's concept became the basis of the home air-conditioner.
