Early commercial applications of air conditioning were manufactured to cool air for industrial processing rather than personal coolness. In 1902 the first modern electrical air conditioning was invented by Willis Carrier in Syracuse, New York. Designed to improve manufacturing process control in a printing plant, his invention controlled not only temperature but also humidity.
