Willis Carrier and the world's first centrifugal chiller.
Carrier’s breakthrough invention opened the door to large-scale comfort air conditioning while improving the effectiveness of process cooling,” said Gaurang Pandya, president, commercial HVAC, Carrier. “Each day we build on that legacy, innovating with purpose to create what’s next, get ahead of changing requirements, unleash the power of digital technology, run smarter with IoT and help customers deploy commercial HVAC solutions aligned tightly with their business objectives.”
Carrier’s conception to combine a centrifugal refrigeration compressor with a shell, a new type of condenser and a chiller on one frame enhanced process cooling in factories around the world. Following the first installation of three centrifugal chillers at a Philadelphia chocolate factory in 1923, Carrier’s innovation soon provided process cooling to rayon manufacturers in India and cracker factories in Mexico.
In 1924, Carrier realised his dream of comfort cooling when the owners of a Detroit department store added centrifugal chillers. The centrifugal technology reliably and affordably delivered comfort air to the public in theatres, stores, restaurants, sports venues, ships, hospitals and office buildings.
A decade later centrifugal refrigeration had driven process air into more than 200 industries. Food and beverage production became safer, hospitals were more comfortable and sanitary and new lifesaving drugs, such as penicillin became possible.
By providing precise temperature and humidity, centrifugal chiller technology has supported the infrastructure of the modern digital age, including electronics of every type, semi-conductor chips, data centres and robotics. These new inventions and new technologies couldn’t have existed without it.
While the fundamental physics of centrifugal technology have not changed in a century, Carrier engineers have never stopped driving new advancements in centrifugal chiller technology. Today, the Carrier AquaEdge 19DV water-cooled chiller provides world class energy-efficiency with its unique free cooling and heat recovery options that boost the total energy savings of the system while using ultra-low global warming potential refrigerant. The AquaEdge 19MV water-cooled chiller offers a wide operating range in a greatly reduced machine size to replace older chillers. Both machines feature the unique EquiDrive two-stage back-to-back compressor technology to dramatically reduce energy consumption.
From digitally enabled applied systems and connected controls to business-process-focused offerings to efficient high-rise residential systems to healthy building with automation systems and sustainability solutions, Carrier HVAC technology continues shaping the future.
