The basic concept of air conditioning was first applied in the ancient Egypt. During that time, the reeds were hung down in the windows from where the water trickled down and cooled the air to make it more humid. In the 2nd century, the Chinese inventor Ding Huan of the Han Dynasty invented the rotary fan, which was needed for air conditioning, with seven wheels 3 metre in the diameter and also manually powered. In 1758, Benjamin Franklin and John Hadley, a chemistry professor at Cambridge University, conducted the experiment as a means to cool an object rapidly. Modern air conditioning is a gift by advances in the field of Chemistry in the year 1902, which is when the first comprehensive electrical air conditioning was invented. The credit for this invention goes to an American engineer Willis Havilland Carrier, also known as the father of air conditioning. The term air conditioning was given by a textile engineer named Stuart H. Cramer.
