His idea remained largely theoretical. The electrical version of air conditioning was invented by Willis Haviland Carrier ( 1876-1950) around 1902 to control temperature and humidity for improved manufacturing process control, and the first practical air conditioning system for a printing plant in Brooklyn, New York. Later expensive air conditioning systems were applied to increase productivity in the workplace. Later still, air conditioning was expanded to improve comfort in homes and automobiles.
