In June 1920, Willis Haviland Carrier prepared a memo that described a novel machine and refrigerant that might significantly advance the art and science of air conditioning.
Already celebrated for his 1911 “Rational Psychrometric Formulae,” Carrier imagined a “centrifugal chiller” and new refrigerant that would not only enhance process cooling in factories around the world, but reliably and affordably deliver “comfort air” to the public in theaters, stores, restaurants, sports venues, ships, hospitals and office buildings.
The electrification of heating presents a significant opportunity to achieve decarbonization goals by reducing or eliminating the use of fossil fuels in traditional building systems such as boilers. The current geopolitical scenario has caused commodity prices to quickly rise and forced businesses, cities and countries to rethink their future dependance on fossil fuels and accelerate the conversion to sustainable alternatives.
An Illinois protective packaging manufacturer was able to reduce their cooling costs by over 60% while also saving around $100,000 each year on system maintenance by replacing their old system with high-efficiency equipment and a streamlined hydronic design. Helped by ComEd efficiency incentives, the plant captured these benefits through an under 2.4 year payback system upgrade project.
With the approaching HFC phasedown, the demand for environmentally friendly cooling systems is driving chiller manufacturers to innovate. Washington-based Pro-Refrigeration, Inc., a leading manufacturer and supplier of chillers for the industrial and beverage processing market, including the dairy, beer and wine industries, recognized an opportunity with CO2 chillers.
