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 100^th 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.

New global study supports healthy buildings as a critical public health strategy

PALM BEACH GARDENS, Florida, 9 September 2021: For the first time on a global scale, new research has found that healthy buildings with enhanced ventilation can improve the cognitive function and health of occupants, suggesting that ventilation and filtration are pre-eminent healthy building strategies, Carrier Global Corporation said through a Press release. Primary support for the study came from Carrier.

The study, COGfx Study 3: Global Buildings, was led by researchers from the Harvard T.H. Chan School of Public Health as part of the renowned COGfx Study series, which examines the impact of indoor air quality on how people think and feel, Carrier said.

The latest study supports the prior studies’ lab and US findings and further supports that indoor air quality is not only good for people’s health and safety, it’s good for the bottom line, as well – through increased productivity, fewer sick days and better cognitive function, Carrier said.

“As more people move toward returning to offices, schools and recreational activities, the health, safety and intelligence of indoor environments have come into greater focus,” said Dave Gitlin, Chairman & CEO, Carrier. “The COGfx Study continues to demonstrate that proper ventilation and filtration of indoor environments plays an important role across the globe in fostering a proactive health strategy. At Carrier, we are focused on delivering innovative solutions and services that positively impact the health, productivity and cognitive performance of occupants of all buildings.”

The COGfx Study 3: Global Buildings examined the impact of indoor air quality on the cognitive function of office workers across six countries – China, India, Mexico, Thailand, the United Kingdom and the United States. The research found that cognitive function declines as the levels of fine particulate matter (PM_2.5) and carbon dioxide (CO₂) increase, Carrier said, referencing the study. Higher CO₂ can be an indicator of poor ventilation in buildings, the company added.

Importantly, mechanical ventilation, such as an HVAC system with efficient filtration, can help to protect building occupants from the negative cognitive effects of PM_2.5 and CO₂, Carrier said. In addition to acute impacts on cognitive function, reducing exposure to PM_2.5 is associated with many other health benefits, including reductions in cardiovascular disease, asthma attacks and premature death.

While the research focused on office employees in commercial buildings, the takeaways are applicable for all indoor environments, Carrier said, adding that as a company it offers numerous products and services that optimize indoor air quality, including a suite of advanced solutions through Carrier’s Healthy Buildings Program that serves key verticals including, healthcare, hospitality, education, retail and marine.

This latest research builds on previous COGfx studies that demonstrated better thinking and better health can be found inside healthier buildings. The first study found cognitive function test scores doubled when study participants were in simulated green building environments with enhanced ventilation as opposed to conventional building environments. The COGfx Study 2 examined real-world building environments in the United Stayes and showed that employees in green-certified buildings showed 26% higher cognitive function test scores and 30% fewer sick building symptoms versus buildings that were not green-certified.
