Willis Carrier

    While watching the film "Nova: Absolute Zero" it was interesting to learn about the historical evolution on the idea of cold. Willis Carrier is known for being the head engineer in inventing the first air conditioning machine in 1902 along side several other men. He got the idea while working in a fan warehouse and implemented his idea to help a printing copy keep the ink on the page during a hot Brooklyn day. The air conditioning system he made was more than just cold, it could also heat and keep a constant humidity. Carrier was always ahead of the game and changed from ammonia to using CFC two years before it was required. Now Carrier is using CO2 systems that reduce the green house gas admission.
