When Was the First Modern AC System?

Before the turn of the 19th century there were always attempts to keep buildings and people cool during the heat of the day. Our ancestors used numerous techniques in architecture and construction to promote the most ventilation and take advantage of the changing of the seasons.

Despite experiments to cool entire buildings with ice and attempts to centralize refrigeration, it wasn’t until 1902 when a young engineer named Willis Carrier invented the first modern AC system. His motive was to try to keep the paper in his printing plant from wrinkling due to high humidity levels. His discovery, of course, led to the Carrier Engineering Corporation, makers of many of today’s most high-quality AC units. Carrier’s first mechanical unit sent air through water-cooled coils, and was designed to control humidity in the printing plant where he worked.

One of the first buildings in the world to use an AC system resembling modern ones was the New York Stock Exchange building. This building used the same large-scale AC machine invented by Carrier, which was then equipment that controlled temperature and humidity by using chilled coils.
