Which American engineer developed the first modern air conditioning system in 1902?
Correct!
In 1902, American engineer Willis Haviland Carrier developed a system that is now considered the first modern electric air conditioning system. Carrier, then only 25 years old, was tasked with solving a problem at the Sackett-Wilhelms Lithographing & Publishing Company in Brooklyn: excessive humidity caused paper to swell and impaired color printing. Carrier designed a system in which air was passed over coils filled with cold water. This caused moisture to condense from the air - at the same time it was cooled. Originally it wasn't about pleasantly cool rooms, but rather about controlled humidity in a print shop. On July 17, 1902, Carrier presented the basic design for the system. In 1906 he received a patent for his “Apparatus for Treating Air”. Carrier later developed the technology significantly further. In 1922 he introduced a practical centrifugal refrigeration compressor that made air conditioning systems smaller and more powerful and promoted their further spread.
