Air cooling and dehumidifying demonstrate engineering's conquest over ambient conditions: sensors, software, and smart control shape air conditioning's second century

摘要

Miles Davis entitled his seminal 1950 jazz album The Birth of the Cool, but from an engineering perspective, the real birth of the cool occurred exactly 100 years ago. That's when Willis H Carrier developed the first practical mechanical-refrigeration system, with a design that is still in use, albeit with numerous refinements. He subsequently founded Carrier Corp, which became a leading supplier of climate-control systems (www.carrier.com).
