Carrier celebrates 100th anniversary of Founder’s invention of centrifugal chiller
DUBAI, UAE, 30 June 2022: On the evening of May 22, 1922, Willis Haviland Carrier invited 300 people to a sheet metal shop in Newark, New Jersey, for a free meal and a boxing match, followed by the unveiling of the first centrifugal chiller technology, Carrier said through a June 30 Press release, adding that it celebrated the 100th anniversary of the invention of the centrifugal chilling machine that in many ways made the modern world possible. Carrier is a part of Carrier Global Corporation.
“[Willis] 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.”
Willis 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, Carrier said. Following the first installation of three centrifugal chillers at a Philadelphia chocolate factory in 1923, Willis Carrier’s innovation soon provided process cooling to rayon manufacturers in India and cracker factories in Mexico, the company said.
In 1924, Willis Carrier realized his dream of comfort cooling when the owners of a Detroit department store added centrifugal chillers, the company said. The centrifugal technology reliably and affordably delivered comfort air to the public in theaters, stores, restaurants, sports venues, ships, hospitals and office buildings, the company claimed.
A decade later, centrifugal refrigeration had driven process air into more than 200 industries, the company said. Food and beverage production became safer, hospitals were more comfortable and sanitary and new lifesaving drugs, such as penicillin, became possible, the company added.
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 centers and robotics, the company said. These new inventions and new technologies couldn’t have existed without it, it added.
Sathya Moorthi, Managing Director, Carrier Middle East, said: “Carrier has evolved over the years from being a manufacturer of cutting-edge equipment to providing solutions that harness the power of variable frequency drives and IoT, ensuring that business-critical activities run at peak effectiveness, and provide operational efficiencies and insights. This demonstrates our commitment to continuously improving energy efficiency while enhancing the comfort levels of the occupants in the harsh Middle East climate conditions.”
Carrier said that while the fundamental physics of centrifugal technology have not changed in a century, its 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 company added. The AquaEdge 19MV water-cooled chiller offers a wide operating range in a greatly reduced machine size to replace older chillers, the company said, adding that both machines feature its unique EquiDrive two-stage back-to-back compressor technology to dramatically reduce energy consumption.
Kingspan Insulation launches product for external ductwork applications
DUBAI, UAE, 5 January 2021: Kingspan Insulation launched the KDuct, which the company described in a Press release as catering to external ductwork applications.
According to the company, the KDuct incorporates its pre-clad ductwork system, made of thermoset, fibre-free pre-insulated duct board with a heavy-duty outer jacket. The company described the product as ideal for external applications, plantrooms, risers, congested spaces and lightweight specifications. The KDuct, Kingspan claimed, offers high performance, rigid, closed-cell insulation core, manufactured with a blowing agent with zero Ozone Depleting Potential (ODP) and low Global Warming Potential (GWP). At the same time, it said, the panels are faced on both sides with an embossed aluminium foil. The new product line would provide ultra-strength and rigidness; cost-savings over traditional exterior ductwork; extra-low air leakage, which does not allow conditioned air to escape; and high-compressive strength, among several other benefits, the company said.
Sarmad Fakhri, Managing Director, Kingspan Insulation, said, “KDuct Ductwork system would help our customers to save extra cost and time due to its lightweight and single-fix properties.” Unlike the traditional approach to ductwork construction, which requires sections to be lagged with insulation, once installed, the KDuct panels are pre-insulated with a high-performance insulation core, the company said. This single-fix and lightweight design, the company added, reduces installation time and transfers the cost benefits to the building owners.
